As a longtime leader in innovative solutions for the restoration of building facades, Sto Corp. serves as a partner by emphasizing preservation-driven systems that integrate modern performance upgrades without compromising architectural character.

Preservation with Purpose

Facade restoration is a great opportunity to replicate historical aesthetics and optimize long-term performance. Visible deterioration on a structure such as cracking, spalling, or fading can be a symptom of underlying issues related to the building envelope. Retaining architectural character in restoration projects is essential. But historical integrity and modern wall science are not mutually exclusive. Facade restoration best practices require respecting the building’s original proportions, materials, and detailing while upgrading the science behind the wall.

Understanding the Condition Before Choosing the Solution

Jumping to a solution without a diagnosis leads to cycles of patching and failing. That’s why a comprehensive evaluation of a restoration project by a skilled, experienced consultant or contractor is a critical first step to success.

Diagnosing existing conditions before restoration involves aspects such as:

• Evaluating Substrate Integrity: Determining if the substrate (concrete, CMU, wood or steel frame) is compromised and needs repair, or if it can support a new cladding if that is being considered.
• Identifying Moisture Intrusion: Pinpointing where moisture intrusion occurred, the impact of the moisture intrusion, and assessing the impact of hydrostatic pressure.
• Defining Scope: Using a data-driven “decision matrix” to choose between surface repair, partial replacement, or high-performance overclad or recladding.

To support this phase, Sto provides more than just materials; we act as a technical partner. Sto maintains an expert support team that can assist in providing project specific solutions and guidance from the early stages of a project through completion. Support may include plan reviews or onsite visits to help evaluate the current state of a building envelope and troubleshoot issues.

Once the initial condition is understood, Sto offers a suite of design tools – such as StoStudio^® or StoInspire^® for color rendering as well as texture and finish samples – to help visualize how a completed restoration project will look, ensuring that the technical solution also meets the aesthetic requirements.

Sto also offers the Sto Wall Selector, System Finder and Documentation Center, which allow professionals to match their diagnostic findings with a fully engineered system rather than just a patch fix.

Strategic Decision-Making in Restoration Projects

The value proposition of facade restoration hinges on a delicate balance: honoring the architectural legacy of the past while complying with modern demands. A building’s heritage value makes it worth saving, but that value is lost if the structure continues to deteriorate.

Moving from patch-and-paint repair to system-based restoration avoids the pitfalls of increased maintenance cycles. By utilizing Sto solutions, project teams ensure long-term effectiveness by mitigating future risk and extending a building’s service life.

A “cheap” repair often becomes more expensive than a full recladding when labor, structural reinforcement, and logistics are factored in. Heavy traditional materials often require the building’s frame to be reinforced which can be an immense hidden cost. Lightweight solutions like StoTherm^® ci EIFS systems, StoCast^® finishes, and pre-fabricated StoPanel^® systems address these needs by reducing structural dead load and minimizing disruption to occupants through faster installation. Choosing integrated systems also ensures compatibility across all materials.

StoCast products are flexible, prefabricated resin cast shapes that can replicate historic textures like brick or wood while offering significant functional advantages. For example, StoCast Wood provides a warm, UV-resistant aesthetic without the downsides (like potential to rot) or maintenance associated with natural wood. Similarly, StoCast Brick is ideal for matching historic masonry without adding massive structural loads; remarkably, one truck of StoCast Brick replaces 15 trucks of traditional masonry. Because these systems are applied with adhesive, they eliminate fasteners that could create thermal bridges or points for moisture entry.

StoPanel systems reduce dead load by using light-weight components – eliminating the need for structural reinforcements, and circumventing fastener stress (since they are a fully adhered system). Because StoPanel is manufactured off-site, it also minimizes disruption to occupied buildings via faster speed of installation, reduced scaffolding and staging, and producing less noise and debris.

Incorporating Future-Ready Performance

Oftentimes, major facade restorations trigger requirements to meet updated energy codes and safety standards. Instead of viewing these as hurdles, restoration best practices suggest using them as opportunities to improve a building’s long-term resiliency and durability.

A good strategic decision is the addition of continuous insulation during the recladding process. High-performance systems, such as StoTherm ci, eliminate the thermal bridges that drain energy and compromise indoor comfort. Pair this with a seamless air and water-resistive barrier like Sto Gold Coat^®, and the restored facade will provide superior air and moisture management, protecting the structural integrity of the building for decades to come.

Enhancing durability after a restoration does not have to compromise architectural expression. Modern wall science, backed by system-based solutions like the kind that Sto offers, allows for both standards to be met and exceeded.

Restoration is a unique process that requires a specialized partner.

Modern building envelopes are increasingly complex due to higher performance demands, tighter codes and layered assemblies. Complexity alone does not create risk, but uncoordinated systems do.

This blog post explores how uncoordinated systems can compromise an envelope and why a single-source envelope system is a better, more strategic decision.

Where Envelope Risk Typically Begins

So, what exactly is an “uncoordinated system”? An uncoordinated system is an envelope comprised of products and solutions from different manufacturers, pieced together in an attempt to create a unified system. The problem is that those products and solutions weren’t designed to work together. Even in a best-case scenario, there will be gaps in your envelope.

Gaps at transitions are only one potential issue. These piecemeal solutions often increase coordination challenges and liability. Other common failure points in multi-manufacturer assemblies include:

• Incompatible materials
• Unclear responsibility for transitions
• Conflicting installation requirements
• Warranty gaps

So, what’s the solution? Simplicity via single-source envelope systems.

What “Single-Source” Really Means

A single-source system is a system where components have been engineered to work together, and there is verified compatibility across all control layers. Integrated components reduce coordination challenges, improve performance reliability and limit long-term risk. At the highest level, single-source envelope systems are a practical risk-reduction strategy. And if anything goes wrong, there is zero confusion about which product manufacturer is responsible.

Many may think there must be drawbacks, such as sacrificing design flexibility. But there really aren’t any drawbacks. Single-source envelope systems simplify design (and can even enhance design freedom), reduce risk and improve long-term performance.

Sto’s Unified Envelope System Approach

Sto’s integrated approach includes proven technology such as StoGuard^® air and water-resistive barriers (AWRBs) and StoVentec^® rainscreen systems, and EIFS continuous insulation solutions with StoTherm^® ci, including noncombustible options. Plus, we offer field applied and prefabricated solutions, all with system harmony across all air, water, thermal and durability control layers.

These systems simplify design and specification with:

• Specification development
• Detail coordination
• Submittal review
• Reduced need for field-level problem solving due to tested assemblies

Benefits for contractors and installers include:

• Fewer incompatible materials onsite
• Clear sequencing and installation guidance
• Reduced rework and schedule disruption
• Trained application and consistent system execution

And for architects and designers, Sto provides flexibility without fragmentation. Our systems support multiple cladding types within a single envelope strategy and deliver design-driven aesthetics with consistent performance.

Why Simplicity Matters More as Codes Get Stricter

The simplicity of a unified system ensures continuity across transitions and penetrations, improving durability and long-term performance. But simplicity is important for other reasons as well. As building codes get stricter, simplicity will be key. Here’s why:

• Increasing performance and fire code requirements raise the stakes
• Simpler, tested systems reduce compliance risk
• Early collaboration ensures performance goals are achieved without overcomplication
• Simplicity is easier to maintain and adapt as requirements change

Simplicity as a Strategy

Clearly, simplicity is a strategic advantage in envelope design. Single-source envelope systems reduce risk, clarify responsibility and make high-performance buildings easier to design, build and maintain.

Sto has been a longtime champion of the system approach. We encourage you to prioritize coordination and accountability from the start and discover the power of simplicity.

We invite you to engage Sto early to simplify envelope design and reduce project risk. To learn more or request a project-specific consultation, explore our Wall Selector, contact us online or call 800-221-2397.

While most manufacturers point you to product literature or their website, Sto gets in the trenches with you. To strategize. To solve. And to create.

Early Engagement is the Key to Success

So, when should you engage Sto on a project? The earlier, the better. We have a wide portfolio of systems to choose from—from EIFS and stucco to rainscreens and prefabricated panels—so there are many possibilities. By understanding the client’s goals, the project challenges and your vision, we can help you zero in on the products and systems that will work best for your project. After all, every successful building envelope begins with understanding the project’s performance priorities, lifecycle goals and environmental context.

Those are just a few of the initial considerations. There are plenty more, and we’re here to help you sort through them.

Key Factors to Selecting the Right System

Sto has numerous advanced tools to help architects. There’s the Sto Wall Selector, the Aesthetic+Product Selector and our Documentation Center, to name a few. These tools simplify the exploration process. Our technical team often points to the Sto Wall Selector as the starting point, as it outlines essential factors every architect should assess when selecting materials and systems for their project. These are a few of those factors.

Timeline

• Project schedules often dictate system choice—prefabrication (Sto Panel) or fast-installing systems (StoPowerwall, StoVentec) can accelerate timelines.
• Early coordination with Sto Representatives ensures constructability reviews and compatible detailing are resolved before construction.

Budget

• Sto systems provide scalable solutions to meet budget constraints without compromising quality.
• Prefabricated Sto Panel Technology reduces onsite labor costs and weather delays.
• StoGuard integrated AWRB systems cut rework costs by simplifying moisture protection across multiple trades.

Performance Requirements

The Secret to Minimizing Disruption: Prefabrication

The problem with traditional construction is the banging, and the sawing, and the cutting, and the mess from it all. With prefabrication, panels are manufactured off-site in climate-controlled facilities, resulting in a more consistent, higher-quality product. Panels arrive ready to install, reducing installation time and allowing facilities to remain operational during the expansion or renovation, reducing disruption to operations.

The benefits of prefabrication include:

• Controlled environment results in more consistent quality
• Less work on the jobsite means less disruption to operations
• Reduced weather-related delays ensure more predictable schedules and tighter budgets

But not all prefabricated panel solutions are created equal. One solution delivers performance, safety and sustainability, while offering virtually unlimited design freedom. That solution is Sto Panel Technology.

Sto Panel Technology – A Trusted Solution from a Trusted Partner

• Prefabrication limits operational downtime, reducing revenue loss during construction phases

Sto Panel Technology: Case Studies

Sto Panel Technology sounds too good to be true, right? But it is true! And we have the real-world stories to prove it. These are just a couple of recent examples of how Sto Panel Technology can make a huge impact on new builds, renovations and expansions.

Banner Desert Medical Center

Location: Mesa, Arizona
Building Type: Healthcare
Construction Type: New

Banner Health’s Desert Mesa Campus established the need for a 58,550 sq ft expansion of the Women’s Tower and provided an opportunity for a multi-level addition. As the project required the construction of a new hospital wing above and adjacent to the existing hospital, with minimal disruption to the day-to-day operations of the existing facility, the need for prefabrication was obvious, and the entire project team adopted a panelized approach from day one.

MKB Construction used a wide variety of prefabricated exterior wall panels to achieve the multi-aesthetic facade, including StoPanel Classic NExT ci, StoPanel Metal ci and StoPanel Back-up with a masonry veneer. Composed of just over 135 panels, the facade for this project was installed in 4 weeks’ time.

Centennial Hills Hospital Medical Center

Location: Las Vegas, NV
Building Type: Healthcare
Construction Type: New

Like most projects, the Centennial Hills Medical Center project originally called for panels to be built onsite. However, an aggressive 40-day installation and the hospital’s location in a residential neighborhood, which made debris containment especially concerning, forced the construction team to reconsider that option.

To address these challenges, they moved fabrication of the 57,092 sq. ft. of StoPanel^® Classic ci panels from the jobsite to their facility, shortening the field schedule by 3 months. By moving to their facility, they were also better able to contain construction debris.

HCA Westside Regional Medical Center

Location: Plantation, FL
Building Type: Healthcare
Construction Type: Expansion

Due to the frequency and threat of extreme weather in the area, South Florida has strict building
code requirements for High Velocity Hurricane Zone (HVHZ) areas and for essential structures such as healthcare facilities. This new addition to the HCA Westside Regional Center had to adhere to the strict Florida Building Code and Notice of Acceptance (NOA) standards, especially for wind-load design and impact resistance requirements. As with most healthcare facilities, meeting or beating the schedule was also of utmost importance.

The StoPanel^® Impact ci assembly allowed FLC Off-Site Construction to incorporate design
requirements and specifications meeting the Florida Building Code and Notice of Acceptance
(NOA) criteria directly into the design and fabrication process. Plus, they were able to install 22,000 square feet of panels in just 14 days.

One Bala Place

Location: Bala Cynwyd, PA
Building Type: Office
Construction Type: Renovation

Built in 1965, One Bala Plaza was an aging, poorly insulated office building. Its restoration included 40,000 sq. ft. of custom-engineered StoPanel^® Classic NExT ci panels installed over the existing facade, delivering a fresh look and vastly improved thermal performance.

The team decided to build a completely new exterior facade right over the existing structure.
Steel angles were bolted along the entire perimeter of the building, then the StoPanel^® system and the new double-glazed ribbon windows were mounted in between. To avoid disturbing tenants, Jersey Panel limited installation to third shift and Saturdays. And by fabricating at Jersey Panel’s offsite facility, installation was complete in only 3 months, further minimizing disruptions.

Maybe not.

While most of these buildings have outlived their useful lives and underperform in virtually every area – energy efficiency, aesthetically, building codes – the bones are usually solid. And that presents the opportunity for another solution: recladding.

The Benefits of Recladding

When you have an older structure, there are pressures from all sides to renovate. The regulatory bodies want it to be brought up to current code. Management wants higher energy standards. Tenants and the community want a more modern aesthetic. Fortunately, recladding can modernize even the oldest dinosaur, enhancing sustainability, lowering costs, and improving performance. Let’s explore each of these benefits a little further.

Sustainability

Obviously, sustainability is a priority whether it’s a renovation or a rebuild. And believe it or not, it is possible to turn an antiquated structure into a sustainable one. In fact, that is one of recladding’s strengths. Here are a few other sustainability benefits of recladding:

• Extends the life of existing building stock
• Avoids embodied carbon from demolition debris and new materials
• Supports climate goals with improved envelope performance

Cost Efficiency

Cost is always an important factor and can, at times, be the determining factor. The cost to demolish and rebuild is not cheap. By choosing to reclad, you can realize there is the potential for some significant cost efficiencies, including:

• Lower upfront costs compared to full rebuild
• Faster schedules minimize revenue loss for occupied buildings
• Reduced permitting and disruption

Design and Performance

One might believe that only rebuilding gives architects and designers the freedom to create a one-of-a-kind marvel of modern science. But you don’t have to rebuild to achieve design freedom. Recladding delivers the ability to:

• Completely transform aesthetics
• Upgrade thermal and moisture performance with modern rainscreen and ci systems
• Improve tenant comfort, acoustic control, and property value

As you can see, recladding offers several benefits and may even prove cost-effective in the long term. Let’s talk recladding specifics by reviewing Sto’s proven recladding solutions.

Sto Recladding Solutions: Proof Positive

Sto is the innovative world leader in building envelope solutions, including wall cladding systems, air barriers, coatings, and restoration systems.

These systems are comprised of a high-performance, energy-efficient wall cladding that integrates StoGuard^® air and water-resistive barrier, GPS, EPS, XPS or mineral wool insulation, and drainage. The nearly limitless aesthetic appearances that can be achieved using Sto textured finishes, Sto Specialty Finishes, or StoCast Brick or Wood custom prefabricated shapes allow for complete design freedom.

Sto offers a few other solutions to aid in your reclad project as well. These include:

• Cladding versatility – Sto’s systemized approach allows for you to select the system most appropriate for your project. Choices of cladding include StoTherm ci systems, StoVentec Rainscreen systems or one of Sto’s other engineered and tested systems.
• Variety of aesthetic options – The vast range of materials, finishes, and design options, include fiber cement, glass, traditional textured finishes, finishes that mimic stone, concrete, metal, masonry veneer, or Sto’s lightweight, custom resin-cast shapes, StoCast Brick and StoCast Wood.
• StoPanel^® Systems – Offering a wide range of aesthetics and finishes to meet your design vision without compromise, StoPanel^® Systems save time with pre-assembled panels ready to install on-site, reducing labor, material waste, and weather-related delays.
• The A.R.T. of reStore^® – For complete facade renewal strategies (aesthetics, repair, transformation), Sto’s reStore program has a program level specific to your restoration needs, offering a single source for materials and services to meet all your maintenance and restoration requirements.

You’ve heard the benefits. You’ve learned a little about our recladding solutions. Now, it’s time to show you what these systems are truly capable of by sharing some of our most recent case studies.

Sounds Compelling, Looks Incredible: Recladding Transformations

The two featured projects below could have easily been total rebuilds. But the owners discovered that they could achieve all their sustainability, performance and design goals with the help of Sto.

Cafesjian Art Trust

Location: Shoreview, MN
Building Type: Entertainment and Cultural
Construction Type: Renovation

A renowned Minnesota businessman and philanthropist, Gerald Cafesjian established the Cafesjian Art Trust to share his collection of modern art with the public. When the trust prepared for a change of address, they realized that the building was well past its prime. Instead of a total rebuild, they opted to reclad and upgrade the facade to better reflect the museum’s mission and artwork.

StoVentec Glass enabled architects to create a customized, visually compelling building facade that could be installed over the existing ribbed concrete and brick exterior walls. The non-combustible continuous exterior insulation and continuous air and water-resistive barrier with StoVentro sub-construction produces an advanced high-performance wall assembly. Additionally, the architect’s vision of a brilliant, colorful building exterior was brought to life with varying shades of blue StoVentec Glass.

The Heritage

Location: New York, NY
Building Type: Multi-Family
Construction Type: Renovation

Rising 35 stories above Fifth Avenue and overlooking Central Park, The Heritage is part of the Empire Building Challenge, an innovative partnership between the New York State Energy Research and Development Authority (NYSERDA) and the private sector, setting out to demonstrate the feasibility of retrofitting tall buildings to comply with low-carbon standards.

To answer the Empire Building Challenge and bring these iconic residential towers into the age of efficiency, the architectural firm employed StoTherm ci, the benefits of which went beyond the great looks and exceptional efficiency. According to King Contracting president Brett Steinberg. “StoTherm ci was the most cost-efficient option for the developer, as metal panels would be almost double the cost, and to rip the facade off and redo it with a brick veneer would be almost triple.”

The result has been a success for everyone involved. The building owner was able to retrofit its aging property, bringing it up to and beyond modern efficiency standards, and the residents now enjoy lower utility costs and a more comfortable living environment.

Decision Point: Reclad or Demolish?

So, when should you reclad versus demolish and rebuild? It’s the million-dollar question. There are certain scenarios where recladding provides clear advantages. A few examples of these scenarios are:

• Structurally sound buildings needing envelope performance upgrades
• Projects constrained by budget or schedule
• Sites with historic or community value worth preserving
• Desire to minimize disruption to building occupants (tenants, patients, etc.)

Recladding: A Sustainable Path Forward

It may seem easier to just wipe out an old building and start over. But a complete rebuild is expensive and can lead to an extended out-of-use time. Our innovative recladding solutions can transform those old dinosaurs into a modern structure in virtually every sense of the term. Increased sustainability. Lower long-term cost.

This blog post aims to answer this question from a technical and building science perspective. But first, let’s discuss some of the variables that make some climates more challenging for exterior claddings.

Climate-Specific Performance Considerations

Everyone in our industry is familiar with the climate zone map. The map exists because different zones present different challenges for construction materials and the construction process itself. Some of the primary challenges include:

• Thermal cycling (freeze-thaw, heat gain)
• Persistent moisture (coastal, tropical, or mixed-humid zones)
• Wind pressures (tall structures, open exposure zones, hurricane-prone areas)
• Combustibility requirements (code compliance in WUI and multi-story)

Those are the primary challenges of some of these zones. But let’s dig a little deeper. What are some of the specific challenges that may be encountered by zone or hazard? We’re glad you asked.

Examples of Challenges by Zone/Hazard Include:

• Hot/Dry – A hot, dry climate significantly impacts UV stability and requires thermal insulation to reduce cooling loads
• Mixed-Humid or Marine – An area that has high humidity and/or is coastal usually battles moisture management via cavity drainage
• Cold – Those zones to the far north that experience long, cold winters encounter thermal breaches that require freeze-thaw durability and continuous insulation
• High Wind/Hurricane – Zones that encounter hurricanes or high seasonal winds test structural strength that can be addressed by mechanical fastening and reinforced sub-framing options.
• WUI/Fire-Prone – Areas that are at risk of wildfires obviously require fire resistance and non-combustible materials

Some of these hazards occur in multiple zones. And every zone has challenges. Now that we have reviewed what some of those hazards are, it’s time to get to our question: can fiber cement perform in all these climate zones and stand up to these hazards?

Fiber Cement: Resilient by Design

The short answer to the question is yes, fiber cement is resilient enough to be used in all these climates. But we’re going to put an asterisk by that statement because there are a couple of important considerations.

First, the fiber cement must be specified for performance in more challenging climates and not just chosen for appearance. This may be obvious, but it’s imperative to prioritize functionality in harsh climates. If the balance tips too far to the design side, you risk exposure to the elements and compromise the structure.

Second: extreme weather has a way of finding the weakest point in your envelope. The way to prevent that is to shift your thinking away from material selection to engineered integration. What we mean by that is you need a system-based approach. By choosing a system over a bunch of random components that may or may not work well together, you’re implementing a systemized enclosure strategy designed to create as tight an envelope as possible.

A system approach provides the best defense against the elements for building owners, but there are other benefits as well. Warranty cohesion is a big one. By having one warranty that covers the entire system, you have single-source responsibility, which means no finger-pointing and the manufacturer has nowhere to hide. Also, when you invest in an integrated system as opposed to individual products, you get performance-tested compatibility. Each component in that system is designed to work cohesively and has been tested to ensure that it does.

There are two general types of cracking: structural and surface. Surface cracking, also known as hairline cracks, are generally 1/16” wide or less; structural cracking is typically wider and deeper. What are some of the causes of cracking and what can be done to prevent them? This blog post is going to crack this topic wide open and provide answers to these questions and more. Let’s begin by looking at the root causes of cracks in commercial buildings.

Common Causes of Facade Cracking

Cracks in a facade can be caused by a wide range of things. The source of the crack can be rooted in environmental impacts. Cracks can also stem from problems inside a building. Here is a short list of the most common causes of facade cracking.

Environmental stressors may include:

• Thermal expansion and contraction – As a building heats and cools, its exterior components expand and shrink, creating stress.
• Freeze/thaw cycles – In colder climates, winter can exact a heavy toll on a building with repeated freeze/thaw events.
• Wind-driven rain and UV degradation – Environmental elements are the most frequent stressors, pounding the exterior of buildings day in and day out.

Structural and substrate-related causes may include:

• Building movement or settlement – Buildings settle over time creating stress points that lead to cracks and while buildings are designed for movement, years of movement or extreme movement outside of normal parameters can increase stress.
• Inadequate substrate preparation – Surface level protection offers one level of defense; if the substrate is left unprotected, surface cracks can penetrate deeper, faster.
• Incompatibility between facade materials – Different materials from different manufacturers don’t always work well together, sometimes leaving weak spots in a building’s envelope.

But how much damage can a crack cause? It can’t be that bad, can it? The consequences of these problems can be very real and very damaging.

The Short- and Long-Term Consequences of Cracks

Surface cracks are more than just cosmetic flaws. They can lead to serious performance issues and costly repairs. Obviously, cracks create an opportunity for moisture intrusion, which can lead to the growth of mold and mildew. Air leakage into the walls can compromise energy efficiency.

Long-term consequences may include material degradation. The constant intrusion of both water and air can damage components found within the wall cavity. The degradation of these systems can lead to more significant water intrusion and compromised climate control for the occupants. In worst-case scenarios, these failures can lead to liability and warranty issues.

But there are ways to address hairline cracks in stucco claddings that help prevent future breaches, extend the facade life, reduce lifecycle costs, and preserve aesthetics. One solution proven to proactively prevent cracks is Sto Crack Defense.

Sto Crack Defense: Engineered for Performance

Sto’s crack prevention technologies protect your investment from the start. Sto Crack Defense, in particular, enhances the durability and longevity of stucco and other facade systems.

Fortunately, Sto Corp. is a company obsessed with color. We love providing architects and designers with the tools they need to bring their creative visions to life. We help them balance aesthetic ambition with long-term performance through innovative materials science. We refer to it as performative aesthetics. And it means beautiful, long-lasting facades. Pigments are, of course, an important part of that equation. But what exactly is a pigment?

Pigments 101: The Basics

Pigments are not the same as dyes. Dyes are soluble colorants known for their ability to produce vibrant, intense colors. However, they are generally less resistant to fading when exposed to light, especially UV rays, compared to pigments.

Pigments, on the other hand, are finely ground, insoluble particles that produce color by scattering light. They are mixed with a liquid medium, known as a binder, to form colorant; the pigment solution used to color coatings and finishes. Colorants provide color and functional qualities, and impact UV resistance, chemical stability, and maintenance of the product.

There are two main categories of colorant: organic and inorganic. There are several differences between the two. Let’s begin with organic colorants.

The Natural Brilliance of Organic Pigments

As the name implies, organic colorants are comprised of carbon-based compounds. Organic colorants are typically made with pigments, solvents, resins (binders), and other additives, including driers, hardeners, stabilizers, surfactants, and dispersants. Resins, typically dissolved in solvents, play a crucial role in forming a protective barrier against corrosion and oxidation. The color, opacity, mechanical properties, and barrier properties of the coating or finish depend on the chemical makeup of the dispersed pigments and the pigment volume concentration (PVC).

What is PVC? Pigment volume concentration (PVC) influences how likely the coating will chalk. PVC refers to the ratio of the volume of pigment particles to the total volume of the pigment and binder in the coating. Essentially, it tells you the percentage of pigment in the polymer pigment matrix. Lower PVC coatings are less prone to chalking.

Organic pigments can create brilliant colors and bold hues, such as red, teal, and magenta. The tradeoff for the brilliant colors achieved is lower UV (ultraviolet light) and heat resistance, which makes the coating prone to fading over time. Additionally, coatings with organic pigments are often more transparent in deeper bases, requiring more coats for full coverage and sealers to minimize fade resistance.

These disadvantages aside, organic pigments are the only way to achieve some vibrant and brilliant colors. Using them wisely can reduce the ongoing maintenance of your building. They are perfect for accents and for use in areas that are smaller in scope. They are less suitable for large facade areas, especially in areas prone to harsh climate conditions.

The Proven Performance of Inorganic Pigments

Inorganic pigments differ from organic pigments because they rely on minerals such as silica, alumina, and titanium dioxide, rather than carbon-based compounds. These minerals are often combined with other additives to improve adhesion, flexibility, and other performance characteristics.

Yielding more muted colors, inorganic pigments are an effective solution to environments threatened by heat, chemicals, and UV radiation. Benefits of inorganic pigments include:

• Durable, long-lasting finish
• Perfect for earth tones, whites, and muted shades
• Exceptional UV and chemical resistance
• High opacity and coverage efficiency
• Heat resistant, ideal for full facades and high-exposure environments
• Environmentally friendly

Our Approach: Integrally Colored Finishes Engineered to Perform

It may seem as if the advantages and disadvantages of organic and inorganic pigments paint a black and white picture, so to speak. But there is an easier way to navigate color selection. At Sto, we believe full system integration ensures color longevity, and innovation enables architects and designers to marry design and performance goals.

Sto offers engineered solutions that provide UV-stable coatings, such as StoColor Dryonic^®, and StoColor Acryl Plus, which enable better performance with darker colors.

Our Best Advice for Specifying Color:

• Choose colors that utilize inorganic pigments for low-maintenance, long-term performance
• If organic pigments are required, consider using Sto Clear Coat Sealer as a topcoat to extend the life of your coating
• Factor in LRV (light reflectance value) and climate considerations
• Use Sto primers to protect pigments and improve opacity and coverage
• Lean on Sto’s technical support for optimized color choices and product recommendations that extend durability and enhance performance
• Consult the manufacturer for product recommendations when utilizing dark, bold colors

Parting Thoughts on Pigment

Pigments are critical to color performance in coatings. By understanding the advantages and disadvantages of organic and inorganic pigments and knowing that there are advanced coatings technical support available, you can ensure you get the aesthetic and performance you’re seeking. As part of our commitment to creative freedom, Sto has developed industry-leading tools to help create stunning facades that are durable, sustainable, and versatile.

In recent years, there has been a growing demand for deep, bold colors in modern architecture. Dark colors add depth and dimension, creating a sense of sophistication, luxury, and exclusivity that can be appealing to high-end clients. Dark colors can also help create a unique brand identity. Standing out is difficult today. Using darker colors can help create a one-of-a-kind aesthetic with a strong visual impact.

Before you go to the dark side, however, there are a few things to be aware of. Let’s start with performance.

Considerations for Dark Colors

We all know that lighter colors reflect more light. For darker colors, the opposite is true: they absorb more light. This exposes the exterior facade to more ultraviolet radiation, which can result in faster fading and the breakdown of organic pigments. Depending on your geography, UV exposure may or may not be a concern. After all, places like Las Vegas have greater UV intensity than places like Toronto.

If darker colors absorb more light, they also, by extension, absorb more heat. In geographies with wide temperature fluctuations, expansion and contraction due to heat and cold cycles can lead to cracking, creating maintenance challenges. Certain systems or materials may also recommend against the use of dark colors. Some wall systems, such as EIFS, that use foam plastic insulation as the continuous insulation can experience deformation when the surface reaches a temperature higher than 167°F. Therefore, it is recommended to use colors with an LRV above 20. An EIFS system using mineral wool is a viable solution when wanting to use EIFS with a dark color, as mineral wool insulation isn’t impacted by the higher surface temperature. (See Tech Hotline 1294 Restrictions on the Use of Dark Colors on EIFS systems).

Also, darker exterior colors tend to exacerbate moisture retention. So, while areas with high humidity or consistent rainfall exposure create ideal conditions for mold and mildew growth on any color coating, darker colors are especially vulnerable.

How LRV Factors Into the Equation

Light Reflectance Value (LRV) also plays a role here. LRV is the total amount of visible and usable light reflected by a surface in all directions when illuminated by a light source. This is measured as a percentage between 0 and 100, with absolute black having an LRV of 0 and white having an LRV of 100. Lighter colors typically have higher numbers than darker colors. The more light is reflected by a color, the higher the LRV; the more light is absorbed by a color, the lower the LRV.

In short, a lower LRV – typically associated with darker colors – absorbs more heat, which contributes to greater overall material stress, potentially shortening the product’s lifespan, fading colors, or impacting other materials in the building envelope, like the insulation.

The Science behind Pigment/Binder Choices for Finishes and Coatings

Inorganic pigments are less affected by light because they are more stable, resisting UV fade for longer periods. Organic pigments, on the other hand, allow for bold, custom hues but tend to fade faster.

Pigment Volume Concentration (PVC) refers to the ratio of pigment volume to the volume of solids in the paint film after drying. It’s a key factor influencing paint performance and properties, such as durability, gloss, and permeability. A higher PVC indicates that the paint has been formulated with more pigment and less binder. Because dark colors require more pigment, chalking is more visible. The aggregate volume in finishes drives the High PVC, making it impossible to fully encapsulate with polymer, and therefore, breaking down the coating or finish quicker.

The Basics of Bases

It is imperative to use the correct base when tinting a coating. TSW (Tint Station White) is not recommended as the base for all colors, especially dark or bold colors. Deep, dark bases are specifically designed to produce darker colors when tinted. Manufacturers often create bases designed for use with bold or dark colors. Just defaulting to what’s in stock can offer a “quick solution,” but is likely not the best solution for long-term performance. Using the manufacturer’s recommended base ensures that the final color is rich and vibrant without the need to add excessive amounts of colorant.

Now for the Good News

Sure, lighter colors perform better. But all is not lost. There are performance enhancers that address many of these issues. Building design alone can help. Roof overhangs and other shading design elements can greatly reduce UV and moisture exposure. Additionally, today’s coatings are becoming increasingly advanced. For example, coatings with fungal resistance can help mitigate the issues of mold and mildew commonly found in humid climates.

One of the easiest ways to extend durability and enhance performance when using dark colors is to use Sto^® Clear Coat Sealer and to specify colors that do not contain organic pigments, as these pigments are less affected by light.

Benefits of Sto Clear Coat Sealer include:

• Maximum Fade Resistance: 8-12+ years (dark organic colors)
• Improved dirt pick-up resistance (easy to clean)
• Improved Mar Resistance
• Improved Fungal and Algal Resistance
• Can be used over standard finishes
• Significantly extends service life vs standard finish

Another great solution is to use StoColor^® Acryl Plus, an acrylic-based, high-performance coating that protects against weather, salts, and environmental pollutants.

StoColor Acryl Plus (Eggshell and Flat) benefits include:

• Excellent Fade Resistance: 6-10 years (dark organic colors)
• Improved dirt pick-up resistance
• Improved Mar Resistance
• Improved Fungal and Algal Resistance
• Can be used over standard and textured finishes for a textured look with a dark color
• More forgiving application than CCS
• Offers much longer service life vs standard finish

Welcome to the Dark Side

Like many others, you’ve heard the call of the dark. Now, you’re aware of the drawbacks and the solutions to those drawbacks, so you’re able to thoughtfully integrate darker colors into your design. In other words, you’re no longer in the dark about darker colors. Welcome to the dark side.

Sto’s core strategy centers on pioneering building solutions that merge scientific innovation with sustainable practices. Our goal is to provide durable, eco-friendly materials that lead the industry in performance and longevity. And that begins with a vigorous and innovative research and development process.

Research, Research, Research, Then Development

At Sto, we believe in exhaustive research. That’s because we are on the hunt for breakthrough innovation that will lead to extraordinary products that push the construction industry forward. There are, after all, enough companies that settle for me-too products. We want to remain the industry leader tomorrow and well into the future.

That requires diving fearlessly into material science. Our research team doesn’t just look at the natural evolution of products within our field, it looks to other industries and even to nature to find innovation that we can learn from and adapt for use in our industry.

Between the natural evolution of a product and the innovation opportunities we discover, we move to development. The priority is always the same: environmental resilience and longevity. While it takes big thinking to pull in out-of-the-box ideas and innovation, sometimes the development part of the process requires getting down to the microscopic level.

Molecular-Level Technology

Often, Sto’s materials are engineered on a molecular scale to enhance properties like water resistance, and algae and mildew resistance. One example of this molecular-level development is with our StoColor Lotusan coating, which borrows properties from the lotus leaf.

Our product development engineers had become a little obsessed with the lotus leaf. It had remarkable properties, like resisting water and dirt, even in extremely wet climates. When they magnified the lotus leaf by 7,000 times, the nanoscopic photograph revealed the plant’s secret. The microstructure of the plant’s unusual surface minimized the contact area for water and dirt. As the surface is also highly water-repellent, the result is water immediately forms droplets and flows off, taking dirt particles with it.

That was the AHA! moment for our engineers. They got to work modeling our new coating’s microstructure after the lotus plant. Like the lotus leaf, StoColor Lotusan minimizes the contact area for water and dirt. Sto’s development engineers also enhanced the surface’s hydrophobic properties. After years of testing, the beauty of Lotus-Effect^® Technology was born. Like the lotus leaf, dirt on StoColor Lotusan facades is consequently carried away immediately by the water that falls on the surface, reducing the likelihood of algae, mold, and mildew.

The Benefits of Sto’s Obsession with Innovation

The Lotusan story is just one example of our obsession with innovation. Our R&D has led to breakthroughs in other areas as well, such as UV resistance, longevity, and ease of maintenance, contributing to a building’s overall lifespan and aesthetic quality.

As we said earlier, our goal is to provide durable, eco-friendly materials that lead the industry in performance and longevity. Other benefits include enhanced building value, extended building life, and advancing building comfort—all with the goal of helping to build a better world.

New Standards of Energy Efficiency

Obviously, we’re always striving to create more energy-efficient buildings as well, enhancing performance for the building owners and comfort for occupants. Our insulated wall solutions systems are either bonded or mechanically fixed to a suitable load-bearing substrate, either on new buildings or for thermal upgrading of existing buildings. These systems lower heating and cooling costs and overall energy consumption.

The integration of air and water-resistive barriers (AWRBs) in these advanced wall systems AWRBs also enhances energy efficiency. By preventing air leakage, a major source of heat loss in buildings, AWRBs help a building operate as efficiently as possible, even in extreme weather conditions.

Sustainability and Environmental Impact

And we’ve learned that colors can affect mood. Red conveys passion and can inspire action and enthusiasm. Orange can create soothing, friendly spaces that spark optimism. Yellow is cheerful and can bring out creativity, intelligence, and wisdom. Blue is confident and secure and has been shown to boost productivity.

According to Arch Daily: “When choosing or recommending a finish for a project, a designer must take into account several variables. How will it shape perceptions? How will it last over time? How will it respond to the lighting conditions of its location at different times of day and night? How will its texture and reflectivity impact the surrounding buildings? This is a decision that will have a significant impact on how the building is perceived and will shape its relationship with its surroundings.”

The Importance of Light

Light is probably the most important consideration when choosing a color. Light affects how we perceive color. According to Metal Architecture, “How light or dark a color appears is determined by how much light the color reflects. Light reflectance value (LRV) is the total amount of visible and usable light reflected by a surface in all directions when illuminated by a light source. LRV is measured as a percentage between 0 and 100, with absolute black being 0% and perfect white 100%.”

Light and color play fundamental roles in architecture. They increase the aesthetic value and determine how we experience architecture. Since these two elements are highly correlated, you cannot simply focus on one without looking at the other.

A Company Obsessed with Color

Sto is committed to providing creative freedom for architects and designers. Our focus on color and its value, continuity, and consistency contribute to the goals we share with the design and building community. Whether providing industry-leading delivery of quality color formulas and samples, a Sto Studio rendering, or assisting in decision-making processes, we will always strive to exceed our customers’ expectations.

Choosing colors is one of the most important decisions that a designer can make. Fortunately, Sto offers advanced color solutions to help choose colors that balance aesthetics and performance.

Excellent patient care doesn’t happen by accident. It occurs as a result of attentiveness, precision, and expertise. No one is surprised they would expect the same from their construction projects.

Unfortunately, the construction industry must be more flexible, as it often struggles with variables beyond its control, such as weather and logistical challenges. However, there are ways to improve the quality and precision of the final product and make scheduling more predictable. One method is pre-fabrication.

Pre-Fabrication Explained

There are two types of prefab construction: modular and panel built. Sto’s prefabrication solution, Sto Panel Technology^®, features prefabricated finished exterior wall panels. The StoPanel^® system panels consist of cold-formed metal framing and all other components in a specified wall assembly, including glass mat sheathing, air and water-resistive barrier, continuous insulation (ci), sub-framing (if applicable), and the facade surface. StoPanel systems deliver what stand-alone components cannot: higher quality and dependability, fortified by third-party testing and code compliance.

The Benefits of Prefabrication

Prefabrication is a trend in healthcare for a reason. Actually, for many reasons. The benefits range from faster construction timelines to improved quality control and potential cost savings by minimizing on-site labor needs and waste. These are crucial factors in a sensitive environment like a hospital or other medical facility where continuous operations are critical.

These benefits sound great, but is there really a difference? Let’s examine some more closely, starting with faster construction timelines.

Construction with Fewer Disruptions

Prefabricated panels are manufactured in a controlled environment with all the various elements built in. As a result, there is greater quality and precision than traditional site-installed components. Because most of the construction is completed off-site, there will be less disturbance at your medical facility and reduced construction risks for workers and hospital operations.

Another point worth mentioning is that prefabricated panels are designed to be installed faster. On average, approximately 15,000 square feet of a building’s exterior surface can be installed per week or approximately 60,000 square feet/month when utilizing a Sto Panel Technology^® system. This is just another way prefabrication enhances schedule certainty.

Potential Cost Savings

The truth is prefabricated panels aren’t the low-cost construction choice. However, they have the potential to unlock massive savings when it comes to a project’s schedule. As mentioned above, fewer workers are needed on-site, and the panels are designed to be installed faster. So, the man-hours for labor are dramatically reduced. Plus, prefabrication projects usually result in fewer RFI’s and change orders and less material waste. All of which could result in significant savings.

Engineered for a Precision Fit

Every prefabricated panel is fully engineered and includes connections for its unique configuration, position, and the structural frame to which it must attach. Typically, the panels are held about one inch off the edge of the slab and connected at every stud with custom-designed steel plates, angles, or other prefabricated connection components as required to carry the design loads and handle the expected movement of the building frame.

With traditional field-installed projects, you’re counting on the engineering of the individual components and that those components will be installed properly to perform well as a unit. With multiple contractors involved and the variability of weather, it’s easy to imagine where some inconsistencies can occur. Inconsistencies create weak spots in a building envelope that can and do affect performance.

Customization for Healthcare Aesthetics

Not only does Sto Panel Technology^® deliver all the benefits of a prefabricated solution, it also offers design freedom. Architects and designers can choose from a wide variety of solutions to achieve a project’s desired aesthetic, such as 3D-printed facades, masonry veneers, resin-cast brick and wood, metal panels, fiber cement panels, and plaster finishes.

StoCreativ^® Granite and StoSignature are two incredible finish options that can help healthcare organizations create the exact look they’re after. StoCreativ Granite is an acrylic-based interior and exterior wall finish formulated for durability and low maintenance that gives the appearance of cut or polished granite. StoSignature is a virtually endless blend of color, texture, profiles, and effects utilizing Sto products that create customizable finished surfaces.

Whether you need to meet facility aesthetic and operational requirements or want to accentuate your brand, Sto Panel Technology makes it possible.

Give That Building a Jacket

This may be stating the obvious but older buildings often lack the thermal efficiency of newer buildings. So, chances are, your retrofit could use a new jacket. Humans adapt their clothing to environmental conditions. Our personal attire is dynamic, or at least that’s a good reason for a diverse wardrobe. Windbreakers, rain jackets, wool overcoats, and insulated, puffy jackets perform different roles for us, providing performance for certain conditions. Some jackets are multipurpose, keeping us warm and dry yet ventilated in adverse weather conditions. Exterior wall assemblies are much like these multi-tasking performance jackets, enduring longer lifespans while protecting against changing weather conditions, safeguarding interior environments, and promoting occupant health and well-being.

But sometimes, a building needs a new jacket, and retrofitting for an aesthetic refresh also provides an opportunity to enhance the wall assembly’s performance. Critical components include proper continuous air sealing and water-resistive barriers, thermal insulation, and a rainscreen ventilation cavity. As we’ll cover in greater detail in this article, these elements collectively form a high-performance exterior wall assembly.

A Modern Rainscreen System: The Perfect Jacket

When retrofitting an old building with a new jacket, air sealing is essential. A continuous air seal is best achieved with careful detailing of the air barrier, particularly at openings and corners and transitions to the roof and foundation. The addition of a rainscreen system then protects inner walls from weather exposure and prevents water and moisture from penetrating the building envelope. The benefits of a modern rainscreen system include:

• Energy efficiency: Rainscreen cladding improves thermal performance, reducing heating and air conditioning costs by up to 40% annually.
• Insulation: When done correctly, an added insulation layer enhances thermal efficiency and limits condensation.
• Protection: The cladding protects the building’s exterior from wind, rain, and snow, extending its lifespan and reducing maintenance costs.
• Structural stability: The air cavity in the rainscreen mitigates temperature variations, reducing structural movements and the risk of cracks.
• Acoustic insulation: An additional insulation layer helps block outside noise, which is beneficial in urban environments.
• Design freedom: With a rainscreen system, you get an exoskeletal system that supports a variety of architectural finishes, such as Sto’s StoCast resin cast shapes that replicate textures found in nature, and StoVentec Glass, a glass-faced composite panel that can be used in StoVentec Glass Rainscreen systems, as well as other beautiful finishes that allow you to create a smooth, textured, or patterned surface.

Components of a Modern Rainscreen System

A rainscreen is made up of several key structural components that work together to manage airflow and moisture effectively; these components usually include:

• Outer cladding material: The cladding is your building’s first line of defense. Depending on the climate zone and local environment of the building, you’ll want to choose the cladding type–fiber cement, metal panel, HPL, specialized render systems, etc.–based on the desired aesthetic, hazards present, and the level of protection that is needed.
• Air gap or cavity: A ventilated space behind the cladding that helps manage moisture. A modern rainscreen system incorporates a more significant air gap than traditional drainscreens to promote drainage and drying of wall assemblies.
• Air and water-resistive barrier (AWRB): This is attached directly to the building’s frame and is the last line of defense against air leakage and moisture intrusion. The AWRB may be permeable or impermeable to water vapor, depending on the climate.
• Exterior Insulation (a building’s overcoat): This outer insulation layer can handle moisture and drying without degrading or reducing its R-value. Depending on the building owner’s thermal requirements and targets, this layer may be supplemented. Also, energy codes require different degrees of exterior wall thermal performance.
• Venting Profiles: Several ventilation options are available to help direct moisture away from the wall surfaces and keep out pests.

Beware the Frankenstein System

As noted above, the fewer manufacturers you have to deal with, the better. Ideally, you’ll have one manufacturer that offers all the components required for your rainscreen system. It is a system, after all. A Frankenstein system is the total opposite. Often, one manufacturer is hired for the aesthetics, another for the air and moisture barrier, and another for sub-construction. A Frankenstein system sets you up for failure in the long term. If something goes wrong, all the manufacturers will point at each other, and you’ll be stuck in the middle. Keep it simple. Find one manufacturer that can provide you with a total solution from the sheathing out because that way, there’s no question about who to contact for questions during design, installation, or after completion of the project.

Seeing is Believing

When sourced and installed correctly, a rainscreen system can be transformative. It functions beautifully, saving you money starting on day one. But what does a modern rainscreen system look like? Something that functional must be ugly, right? Quite the opposite. The right rainscreen system gives your architect the freedom to achieve virtually any look. But don’t take our word for it; see for yourself. Here are a few real-world examples of the possibilities. Keep in mind every one of these examples is a retrofit. It makes the finished product even more incredible.

Cafesjian Art Trust

A renowned Minnesota businessman and philanthropist, Gerald Cafesjian established the Cafesjian Art Trust in greater Minneapolis to share his collection of modern art with the public. Cafesjian had a particular passion for the medium of glass, inspiring him to assemble an extensive collection of contemporary glass sculptures from artists such as Victor Vasarely, Georges Braque, Joan Miro, Arshile Gorky, and more. When the trust prepared for a change of address, they realized that the building’s facade needed a substantial upgrade to reflect the museum’s mission and artwork better. Mohagen Hansen Architectural Group envisioned a brilliant, colorful building exterior brought to life with varying shades of blue StoVentec Glass.

In three shades of blue–Dienes Sari, Lemanus Blue, and Sapphire Splash–StoVentec Glass allowed architects to deliver a customized, visually compelling building facade that could be installed over the previous exterior walls, which comprised ribbed concrete and brick. StoVentec Glass is an open-joint drained, back-ventilated rainscreen wall system that combines superior air and weather tightness with thermal performance. The non-combustible continuous exterior insulation and continuous air and water-resistive barrier with StoVentro sub-construction produces an advanced high-performance wall assembly. StoVentec Glass panels are manufactured by fusing colors directly into the glass before toughening to create a permanent color that will not wear, scratch, fade, or incur water damage.

As a retrofit project, the StoVentro subconstruction is attached to the existing sound substrate with bracket connections, enabling the 1,700 square feet of StoVentec Glass panels to connect to a flat plate.

StoVentro sub-construction is an adjustable, thermally efficient structural system of brackets, rails, fasteners, and accessories for rainscreen wall cladding assemblies. The sub-construction absorbs wind and dead loads on the facade and incorporates corrosion resistance.

“The solutions from Sto enabled us to keep the exterior envelope intact, so we avoided energy and water intrusion concerns. We were able to dress up the exterior without being invasive or labor-intensive. The grid system allowed the freedom to choose sizes and colors to create our vision with a unique pattern.”

Innovation Outpost

Innovation drives progress. And in Amarillo, TX, there is a new hub for innovation on the campus of Amarillo College. It is called Innovation Outpost, and the building’s renovation nods to the past with an eye on the future. The structure, which was the former site of Amarillo High School, holds significant meaning in the community, and it has now been rehabbed with innovative, high-performance, industry-leading products that illustrate the purpose of the new space.

The project needed to be a “large box” with no windows, tailored initially to meet the needs of the proposed first tenants that would utilize the space as a visual effects studio with 360° cameras. Natural light from window openings would have disrupted such an atmosphere. There was also interest from local film studios, but the building ultimately served as a performance space, similar to a Ted Talk environment.

The architect specified a StoVentec^® Glass Rainscreen facade with a Stopsol mirrored glass finish. This allowed them to flawlessly execute their design vision–priority number one–while providing ease of installation and long-term performance. The result is an advanced, high-performance wall assembly incorporating all the necessary control layers, sub-construction, insulation, and exterior cladding from a single source: Sto. For the project team and installers, this means one supplier, warranty, and point of contact for the exterior facade. This translates to time, labor, cost savings, and valuable peace of mind.

Innovation Outpost mirrors what Amarillo College wanted in a building representative of innovation. With the help of Sto, the structure is a campus standout, catching the eye of onlookers while reflecting Amarillo’s surrounding built environment, including the Sante Fe Building and the vivid neon sign bearing its name.

Sheen: A Closer Look

The appearance of a coating’s sheen is influenced by several key factors: light interaction, surface texture, material composition, and environmental conditions. The fundamental principle behind the sheen is the reflection and absorption of light. When light hits a surface, some is reflected while some is absorbed, which determines the appearance of the sheen. Glossy surfaces reflect more light, creating a shiny appearance, whereas matte surfaces absorb more light, resulting in a subdued finish.

Surface roughness and texture also play a crucial role in the perception of sheen. Smooth surfaces tend to reflect light more uniformly, enhancing the gloss effect, while rough or textured surfaces scatter light in multiple directions, reducing the gloss and creating a matte appearance. The formulation of the coating itself is another vital factor. The coating’s composition of binders, pigments, and additives affects how light interacts with the surface. Higher binder content typically produces a glossier finish, while higher pigment concentration can create a more matte effect by scattering light.

The angle of incidence, or the angle at which light strikes the surface, can change the perceived sheen. For instance, a surface may appear glossier when viewed from a certain angle compared to when viewed head-on. Environmental factors, such as humidity and temperature, can also impact the final appearance of the sheen. These conditions can affect the coating’s drying process and final texture, influencing its reflective properties.

The Different Sheen Levels

Finishes may go by different names depending on the coating, but there are essentially three standard types: flat/matte, eggshell/satin, and semigloss/high-gloss. Here’s a recap of the pros and cons of each:

• Flat/Matte – Provides a smooth appearance that doesn’t reflect light directly, making imperfections less noticeable.
• Eggshell/Satin – Offers more durability and a slightly higher reflection than matte.
• Semigloss/High-Gloss – Resistant to mildew, dirt, and stains, semigloss is bright and shiny and, as a result, reveals imperfections.

Balancing these factors with aesthetics goals, the building’s location and surface type helps ensure a beautiful finish.

The Importance of the Coating

Sheen is important–it’s the finishing detail! But the right coating will help you tell the story. Sto’s high-performance architectural coatings not only enhance the beauty of your building but also provide superior protection against the elements.

• StoTique^® – an exterior and interior coating that achieves an “antique” mottled effect or other custom decorative effects. Use it over existing EIFS, stucco, previously painted wall surfaces, or any Sto textured or smooth finish coating.
• StoColor^® Texture – an acrylic-based textured coating used over prepared vertical concrete, stucco, existing EIFS, tilt-up, or masonry surfaces.

Projects that Showcase the Impact of the Right Coating and the Right Sheen

The right architectural coating with the right sheen makes all the difference. Here are a couple of case studies that prove the point.

Sheen in Action: Houston House

Project: Houston House
Location: East Village, New York
Construction Type: New
Systems and Products: StoTherm^® ci, Stolit^® Milano

Houston House, located in New York City’s East Village, is an excellent example of how sheen can achieve a modern, stylish look while maintaining practicality. The project utilized innovative techniques to replicate the appearance of sleek metal panels, driven by the need for a high-end, contemporary aesthetic that resonates with the vibrant neighborhood.

The building’s finish is designed to mimic the sheen and texture of metal panels. This finish provides a smooth, reflective surface that captures light beautifully, creating an eye-catching facade. The ability to reflect light in a controlled manner gives the building a polished, upscale look, enhancing its visual appeal in the bustling urban environment.

The application process was crucial in achieving the desired metal-like sheen. Skilled applicators meticulously applied the finish in multiple coats, sanding each layer to perfection. The final coat was troweled to create deep grooves, imitating the joints of metal panels. This attention to detail ensured a uniform, glossy finish that convincingly replicates the look of metal.

One of the significant advantages of using a specialized finish over actual metal panels is its superior thermal performance. The system provides continuous insulation, which helps regulate the building’s temperature and reduces energy consumption. Additionally, the finish offers excellent durability and weather resistance, crucial for withstanding New York City’s harsh winters and hot summers.

Moreover, this innovative finish is more cost-effective than traditional metal panels. It delivers the same high-end appearance without the associated expenses, making it a practical choice for developers looking to balance aesthetics and budget. This approach enhances the building’s exterior and contributes to its sustainability and energy efficiency.

In conclusion, the Houston House project demonstrates how modern coating technologies can effectively use sheen to achieve a sophisticated, metal-like appearance. The finish provides a durable, energy-efficient solution that meets aesthetic and practical requirements, setting a new standard for urban residential design.

Coating Can-Do: Steamboat Grande

Project: Steamboat Grande
Location: Steamboat Springs, CO
Construction Type: Renovation
Systems and Products: StoColor^® Lotusan^®

Located a few steps from the base of the Steamboat Ski area, the Steamboat Grand Resort is a popular luxury resort in Steamboat Springs, Colorado. At an altitude of 6,900 feet, the exterior facade is exposed to 300+ days of sunshine per year and some of the highest snowfall totals in the state. The exterior of this 12-year-old ski resort hotel needed a facelift, and the owners were looking for a solution that would help retain the resort’s curb appeal. It was the perfect project for StoColor^® Lotusan^®, the super hydrophobic exterior coating that produces a finish with self-cleaning properties using Sto’s Lotus-Effect^® technology.

StoColor Lotusan is a flat exterior wall coating modeled on the microstructure of the lotus leaf. The lotus-effect technology, engineered by Sto, imparts super-hydrophobic properties to the coating, which, along with superior self-cleaning properties, resists soiling, mold, mildew, and algae. It also has excellent weather and UV fade resistance.

Michael Lomas, vice president and general manager of The Steamboat Grand, was pleased with the outcome. “Sto did an excellent job matching the paint colors, and the StoColor Lotusan looks excellent.”

Fortunately, there’s a comprehensive, proven solution that delivers on these fronts and others. It’s called a Rainscreen System.

A complete Rainscreen System is comprised of several key structural components that work together to manage airflow and moisture effectively; these components include:

• Outer cladding material: The cladding is your building’s first line of defense. Depending on the building’s climate zone and local environment, you’ll want to choose the cladding type–fiber cement, metal panel, HPL, specialized render systems, etc.–based on the hazards present and the level of protection needed.
• Sub-construction: a structural system of brackets, rails, fasteners, and accessories that serves as the framework for the outer cladding material. This system absorbs both the wind and dead loads on the facade and is adjustable, accommodating uneven substrates and various facade cladding materials.
• Air gap or cavity: A ventilated space behind the cladding that helps manage moisture. A modern rainscreen system incorporates a larger air gap to promote drainage and drying of wall assemblies.
• Exterior insulation: This outer layer of insulation is capable of handling some moisture and drying without degrading or reducing its R-value. Depending on the thermal requirements and targets, this layer may be supplemented. Also, Energy codes require different degrees of exterior wall thermal performance.
• Air and water-resistive barrier (AWRB): This is attached directly to the building’s substrate and is the last line of defense against air leakage and moisture intrusion. Depending on the climate, the AWRB may be permeable or impermeable to water vapor.
• Venting profiles: There are several ventilation options available to help direct moisture away from the wall surfaces and to keep out pests.

Today’s rainscreens are nothing short of marvels of modern science. If you’re considering installing one, you’ll want to be aware of building codes that have impacted the implementation of these systems.

An Evolving Building Code

In recent years, we’ve seen a wave of new building codes. Many of these provide specifications that impact the implementation of a rainscreen system. Below are a couple of examples.

2021 Building Code Changes for Water-Resistive Barriers

Evolving building codes aim to create more resilient buildings. The 2021 International Building Code (IBC) and International Energy Conservation Code (IECC) made several changes to air and water-resistive barriers (WRBs) and air leakage, including:

• WRB compliance methods can include materials other than #15 felt.
• Registered design professionals or approved agencies must verify and commission air barriers when not testing
• Air barrier and air sealing details must be included on project drawings
• Air leakage testing requirements now include residential and non-residential buildings
• Performance verification is now required for buildings that are not tested
• Requirements to seal basements, slabs, and unvented crawlspaces at any penetration in the foundation or slab

Section BC 718.2.6

This New York City Building Code outlined the requirements for fireblocking within concealed spaces of exterior wall coverings, including the conditions and locations where fireblocking is required. Fireblocking must be installed within exterior wall assemblies that contain combustible components even when the wall assembly has previously passed the NFPA 285.

Assembly testing is becoming more and more critical in these new fire codes. Buildings must have a cohesive assembly designed to minimize fire risk, such as StoVentec, which is a fully tested assembly. Multiple wall claddings from various suppliers will be more heavily scrutinized in the years ahead.

The Importance of Proactive Moisture Management

Moisture accumulation within a building structure can cause problems such as water stains, ice damage, peeling paint, wood deterioration, mold, and mildew. Liquid water forms when water vapor in the building meets a surface with a temperature lower than the dew point of the air.

Whether or not the building is air and weather-tight can considerably affect thermal performance. A drafty, leaky building will undermine efforts to insulate, as heat will escape through the gaps that cause drafts and leaks.

For all these reasons and considering that water intrusion is a growing problem, the industry is pushing building owners to be more proactive in controlling moisture.

According to the E.P.A., a building’s design must include three features to control moisture. These features are:

• Controls bulk liquid water from snow, rain, etc.
• Stops a buildup of indoor humidity and water vapor migration by diffusion and airflow to minimize condensation and moisture absorption into cool surfaces and materials
• Made with moisture-resistant building materials

These features can be found in a modern rainscreen system like StoVentec^® Rainscreen^® Systems. Qualitative and quantitatively measured for rainscreen performance via AAMA 509 which tests wall assemblies against both static and dynamic air pressure with water spray simulating severe weather conditions and rates each system with classifications for water and ventilation.

An Innovative Solution that Meets Expectations and Standards

StoVentec^® Rainscreen^® Systems aim to exceed building code requirements by providing superior moisture management and resilience against severe weather, ensuring long-term building performance and durability.

StoVentec Systems are a complete, fully-tested, and code-approved high-performance ventilated Rainscreen system. This includes a best-in-class air and water-resistive barrier, robust mineral wool continuous insulation, the most installer-friendly, adjustable sub-framing system available, and StoVentec Rainscreen cladding.

Benefits of StoVentec Rainscreen include:

• High-quality air and water-resistive barriers
• Non-combustible insulation
• Adjustable sub-framing
• Accommodates a wide variety of finishes and aesthetics

System Versus Component Approach

A system approach is when you specify a complete system from one manufacturer, and the components are all designed to work together. Sto offers a complete Rainscreen System with comprehensive testing, third-party code compliance evaluations, Florida Approvals and Miami-Dade NoAs. For example, Intertek Code Compliance Research Report 0454 evaluates the StoVentec Render and Masonry Veneer Facades systems for physical properties, weather resistance, wind resistance, surface burning characteristics, fire-resistance-rated construction, and use in Types I, II, III, and IV construction against the IBC, IRC, Florida Building Codes, and California Building Codes. The report also references and incorporates the independent evaluations dedicated specifically to the various Sto air and water-resistive barrier options, the all-important last line of defense in rainscreen wall systems. Further, the evaluation is built on a quality assurance program with independent random audits of production facilities which verifies the StoVentec system components are manufactured according to strict quality controls.

Other manufacturers only offer wall components, e.g., a single element in the system, such as cladding or insulation, leaving it up to architects and contractors to determine how these various bits and pieces should all come together. The component approach presents a range of challenges.

Challenges with the Component Approach

• Components aren’t always designed to work together, resulting in design collisions
• Many materials, players, and warranties often result in no party accepting full ownership of a problem
• Achieving aesthetic goals while meeting code requirements can strain a budget
• Misalignment of metal panels due to incompatibility/improper use of facade layer with sub-structure layer

Benefits of the System Approach

• Seamlessly connects design and construction
• Fewer products and subcontractors
• Improved constructability and project delivery
• One warranty – single supplier
• Compatibility of components
• Fully tested assemblies
• Weathertight transitions due to a single AWRB

When you select a complete Rainscreen System, you should receive details from the manufacturer defining:

• Air & water-resistive barrier
• Support structure, including attachment to the substrate
• Exterior insulation
• System ventilation
• Finish cladding
• Testing & warranty information

Real-World Applications and Compliance

It’s a harsh world out there, and StoVentec is up to the challenge. Here are some highlights from a couple of projects that demonstrate the possibilities.

Zislis Residence

Location: Manhattan Beach, California, USA
Building Type: Residential
Construction Type: New

When Michael Zislis, a successful entrepreneur, hotelier and restaurateur, was ready to build a home on the California coast for his young family, he wanted the exterior to be bold. When he learned about the enhanced aesthetic value and advanced performance properties of StoVentec Glass, Zislis was immediately intrigued.

With the home’s beachside location, StoVentec Glass was the ideal product. The multiple-sized panels of StoVentec Glass in varying shades of blue provide a unique appearance for a residential home. Because the product is tempered glass, it maintains reflective properties for a dazzling, durable exterior finish. The glass-faced panels integrate with thermal insulation and an air and moisture barrier to create one complete system that delivers stunning curb appeal and optimal performance characteristics.

Kalamazoo Justice Center

Location: Kalamazoo, Michigan USA
Building Type: Institutional
Construction Type: New

Located in downtown Kalamazoo, MI, the Kalamazoo Justice Center appeared to be a construction challenge. The building design featured a large glass expanse on the south side of the building, a curtainwall that would maximize natural lighting for the interior spaces. That same south-facing side of the building was to include a ground-floor pre-screening lobby. For the fascia of the one-story lobby space, the architects needed a product that visually extended the aesthetic of the modern glass curtainwall.

StoVentec Glass was the perfect fit since it is an insulated glass panel rainscreen system without visible hardware, so the fascia doesn’t feel like a framed curtainwall with hardware on the top, bottom, and sides. The fascia band on the lobby entrance area features nearly 700 square feet of StoVentec^® Glass in an Ad Weiss Optiwhite Glass (9001W) color.

StoVentec^® provides the striking visual effect the architects desired with the added bonus of delivering on performance and durability.

Municipalities nationwide are scrutinizing fire regulations, especially for combustible exterior wall assemblies. In 2022, New York City introduced the NYC Building Code (BC), section BC 718.2.6, for constructing exterior wall assemblies containing combustible components. New York City authorities enacted these changes because of the density of high-rise structures in the city and their belief that current NFPA 285 testing did not address all concerns regarding the spread of fire where foam plastic and other combustible materials are used in exterior wall assemblies. Additional municipalities are likely to follow the New York Code, which requires non-combustible fireblocking to be incorporated into EIFS, MCM, HPL, FRP, and any other cladding with foam plastic insulation.

A Fireblocking Breakthrough Engineered by Sto

Driven by a commitment to innovation and safety, Sto Corp. developed a fireblocking solution to meet the latest rigorous fireblocking requirements for combustible exterior wall assemblies.

Sto Fireblocking is a unique, patent-pending solution that incorporates the use of Sto Lamellas, a non-combustible mineral wool product. Sto Lamellas are 48 inches long and 4 inches tall, precision cut and available in various thicknesses to accommodate R-value requirements. The product is adhered and, therefore, does not create any thermal bridging. It seamlessly integrates into StoTherm ci GPS/EPS, StoPowerwall ci, and StoVentec Rainscreen systems, offering a complete fireblocking solution for a wide range of applications.

Sto’s fireblocking solution is fully compliant with the new 2022 New York City Building Code (BC), section BC 718.2.6).

Fully Tested and Trusted Technology

To develop this innovative fireblocking solution, Sto leveraged over two decades of proven technology already utilized overseas. Lamellas have been fully tested and trusted across Europe for over two decades. Sto Lamella allows architects to design an energy-efficient building with lightweight cladding that is adhered to the substrate and, therefore, penetration-free. Plus, with Sto’s innovative solutions, virtually any aesthetic can be achieved, and as always with Sto, the systems include a complete air and water-resistive barrier.

Wall Systems that Meet the Most Stringent Fireblocking Requirements

These new building codes impact all exterior wall assemblies with wall coverings or claddings composed of other combustible materials, such as Metal Composite Materials (MCM), High-Pressure Laminates (HPL), Fiber-reinforced Plastic (FRP). When incorporated into StoTherm ci systems, StoPowerwall ci, or StoVentec Rainscreen systems, Sto Lamella provides a 2022 NYC BC code-compliant building envelope, tested in accordance with NFPA 285. Sto Fireblocking gives architects, contractors, and owners the confidence and ability to use wall systems that offer innovative design, are highly efficient, and meet the most rigorous building codes for fireblocking.

Engineered by Sto Corp. Approved by NYC.

The way in which the fireblocking layer in Sto Lamella is engineered using lamellas represents a significant advancement in fire safety technology. It is, quite literally, where safety meets innovation.

While it was engineered by Sto, the innovative world leader in claddings, air barriers, coatings, and restoration systems, this fireblocking breakthrough has been approved by New York City, the city with the most stringent building codes in the world.

It wasn’t so long ago that we believed insulation alone could protect a building from all the damaging elements outside. But after decades of costly repairs due to water intrusion, mold and mildew, and corroded structural component repairs, along with advances in building science, we learned there’s more to effective thermal and moisture control—a lot more.

Thermal and moisture control are so important that they are two of the five planes of control needed for buildings to be energy-efficient, durable, safe, and sustainable while still providing aesthetic appeal. The five planes of control working in unison comprise The Perfect Wall.

Knowing how important these control layers are, let’s tackle them one at a time, starting with moisture control.

Moisture Control 101

Moisture accumulation within a building structure can cause problems such as water stains, ice damage, peeling paint, wood deterioration, mold, and mildew. Liquid water forms when water vapor in the building meets a surface with a temperature lower than the dew point of the air.

Whether or not the building is air and weather-tight can considerably affect thermal performance. A drafty, leaky building will undermine efforts to insulate, as heat will escape through the gaps that cause drafts and leaks.

In recent years, moisture management has become a focus of building owners and manufacturers due to growing awareness of its impact, higher expectations for building performance, and more stringent building codes and regulations. At Sto, we are proud to be a leader in innovative, sustainable building solutions that enhance aesthetic value, durability, and energy efficiency, addressing the evolving needs of modern construction. The StoGuard® System is one such innovative system.

Seamless Control Over Air and Moisture

Unlike building wrap barriers that are penetrated by staples and fasteners for their

attachment, the StoGuard® System provides seamless control over air and moisture to improve building performance and occupant comfort. Fully tested and compliant with the most stringent green construction codes, StoGuard systems are an ideal choice for design professionals who wish to employ one continuous, fully compatible air and water-resistive barrier system for all exterior walls on multi-cladding buildings. Benefits of StoGuard systems include:

• A fluid-applied system that forms a seamless air and water-resistive barrier
• Protects against moisture intrusion and unwanted air movement
• Variety of air and water-resistive barrier (AWRB) membrane products to choose from, depending on project requirements
• All Sto systems incorporate an AWRB, vital for maintaining the integrity of the building envelope and preventing moisture-related issues like mold and rot
• Accessories designed for use with Sto fluid-applied membranes at movement joints, substrate transitions, penetrations and rough openings are available
• A fully tested and proven system
• One supplier for all components means one warranty covers everything

The Importance of Continuous Insulation

Now that we have moisture control covered, let’s talk about thermal control. Heat loss can significantly affect the cost of operating a building and the comfort of those inside. In most climate zones, energy codes prescriptively require continuous insulation in wall assemblies for commercial and residential construction. Sto has more than 40 years of experience and practical application of insulated wall systems, so you can rely on us to provide the right solution for your needs. Thermally insulating the exterior of the wall structure with continuous insulation makes sound technical sense on several levels.

• The building is effectively wrapped in a thick, well-insulated and protective blanket
• The effects of thermal bridging are minimized, and the ability to achieve high thermal performance is simplified
• When combined with high-performance finishes, the insulation layer keeps the wall structure warm and dry
• Maintains the temperature of the building wall structure above the dew point, reducing the risks for condensation caused by water vapor diffusion

One of the most advanced continuous insulation wall systems available is StoTherm® ci.

More Than Insulation, A Complete System

StoTherm® ci is a decorative cladding with continuous insulation and StoGuard Air and Water-resistive Barrier combined with Sto high-performance finishes. This advanced exterior insulation and finish system provides superior energy efficiency by combining insulation with aesthetic and protective layers, which is crucial for managing thermal bridges and enhancing overall thermal performance.

When it comes to complying with the rapid changes in energy standards, StoTherm ci systems consistently offer more than most other wall systems. The seamless cladding systems provide optimal performance that meets or exceeds ASHRAE design standard 90.1-2019, the 2018 IECC energy code requirements for continuous insulation, and Title 24 requirements for energy efficiency.

Combining innovative design and high-level performance, StoTherm ci offers a unique approach to wall system design. Choose from a wide range of colors and textures for every exterior, giving you the freedom to create truly unique features. No matter the look or looks of the building, StoTherm ci systems offer unprecedented flexibility to your building’s design. The possibilities are virtually limitless, from architectural shapes and eye-catching finishes to high-performance coatings.

Based on testing in compliance with NFPA 285 and NFPA 268, all StoTherm ci systems are suitable for use on noncombustible construction. With the Sto Fireblocking option, Sto also offers a unique patent-pending solution to comply with the 2022 New York City Building Code (NYC BC), which requires fireblocking for exterior wall assemblies that contain combustible components such as foam plastic insulation, as stated in BC 718.2.6.

A Historic Building Gets an Energizing Facelift: A Case Study

Modern technology is rescuing old buildings from their thermal and moisture challenges every day. The Lido Beach Towers Condominium in Long Island, New York, is the perfect real-world example of how the right system can make an old building new again.

With over 100 leaks in 140 units, the Lido Beach Towers had fallen far from its glory days as an upscale beachfront hotel on the Atlantic Ocean in the early 1900s when it was known as The Pink Lady. The deterioration accelerated in the years following its conversion to a condominium property in the 1980s.

Fortunately, the building owners recognized that it was time to address the problems at their core and add layers of protection to restore some of this storied building’s former glory. Read the case study and watch the transformation on video.

Sto is proud to be a leader in sustainable building practices that reduce maintenance costs and enhance indoor air quality. Our innovative solutions, which provide greater thermal and moisture control for building owners, have been proven and trusted for decades. We invite you to learn more about StoTherm ci, StoGuard, and our complete offering of wall systems. For more information about Sto Corp, visit Stocorp.com.

The post Thermal + Moisture Control in Modern Construction appeared first on Sto Corp..

A significant development in the evolution of building protection occurred in the 19th century during the Industrial Revolution. Construction became recognized as separate from design. Physics, mathematics, chemistry and thermodynamics were all being developed and applied to create building science as a discipline. At the same time, architecture, engineering and construction were all becoming more defined. Suddenly building protection was about much more than insulation.

A Highrise Changes the Game

Often referred to as the world’s first skyscraper, the Home Insurance Building in Chicago was erected in 1885 and stood until 1931. The building was designed by William Le Baron Jenney and weighed as much as one-third of typical masonry buildings, which concerned city officials.

According to History.com, “His revolutionary design utilized an inner skeleton of vertical columns and horizontal beams made out of steel. This was in stark contrast to earlier structures, which were supported by heavy masonry walls. Steel was not only lighter than brick, but it could carry more weight. With this new method of construction, lighter masonry walls could be “hung,” a bit like curtains, from the steel frame. As a result, the walls of the building didn’t have to be as thick, and the structure could be much higher without collapsing under its own weight. Buildings with this type of frame could also have more windows, as the steel frame supported the building’s weight and the stone or brick exterior merely acted as a “skin” to protect against weather.”

The emergence of building science led to this project, marking the building envelope’s beginning.

Science Fills in the Insulation Gaps

While insulation had improved since the days of mud and fur, it was still built on the idea that the Greeks had developed hundreds of years before. Fortunately, science and technology would also benefit this necessary building material.

One of the most significant developments was the widespread use of fiberglass insulation in the 1930s. More recently, it was the increased use of polyurethane foams for filling the cavities between walls. These more advanced products helped our homes and buildings achieve greater comfort while improving energy efficiency.

Insulation That Achieves More with Less

At Sto Corp., sustainable construction is ingrained in our company’s DNA. This commitment guides us in our decision-making and product development. Our GPS insulation is the perfect example of our continuous pursuit of greener products, representing the future of insulation. GPS (graphite polystyrene) is a rigid, graphite-enhanced, 100% closed-cell expanded polystyrene insulation board. We use graphite because it is the most stable form of carbon – safe and chemically inert. Plus, it reduces thermal conductivity and increases the R-value by as much as 25%.

The primary difference between GPS and traditional insulation products is that GPS insulating boards are thinner. In fact, they are up to 20% thinner than other rigid insulation boards. That means less material is required to achieve the same R-value. And the product itself is recyclable, making it more environmentally friendly.

For additional information on the various types of insulation offered by Sto and to compare the features and benefits of each, visit our insulation comparison web page.

Advancement in Material Science and Engineering

With each passing year, breakthroughs in materials science and technology push the boundaries of what’s possible, leading to stronger, more sustainable and more resilient buildings. Nanotechnology is enhancing construction materials with improved strength, durability and thermal conductivity. The result is layer upon layer of building protection that is more advanced than ever.

Smarter, Longer-Lasting Coatings and Finishes

At Sto^®, we have a long, proven history of developing innovative coating technologies. Now, we’ve developed a group of architectural coatings that provide more value by providing more functionality. Sto Intelligent Technology + Design (iQ Technology) interweaves innovation with design to offer high-performance coatings with unique attributes based on biomimicry principles that enhance aesthetics and improve occupant comfort.

The functionality behind StoColor^® Dryonic^® and StoColor^® Lotusan^® is inspired by nature and designed to address the true needs of a building, not just the standards. Because these coatings deliver improved function through optimized product attributes, property owners will realize greater durability and lower lifecycle costs. This technology is also available in StoLit Lotusan, a textured finish that captures the look of traditional plaster, brick, or limestone with self-cleaning properties.

State-of-the-Art Rainscreens

Today’s rainscreens are nothing short of marvels of modern science. They are comprised of several key structural components that work together to manage airflow and moisture effectively; these components include:

• Outer cladding material: The cladding is your building’s first line of defense. Depending on the building’s climate zone and local environment, you’ll want to choose the cladding type–fiber cement, metal panel, HPL, specialized render systems, etc.–based on the hazards present and the level of protection needed.
• Air gap or cavity: A ventilated space behind the cladding that helps manage moisture. A modern rainscreen system incorporates a larger air gap to promote drainage and drying of wall assemblies.
• Air and water-resistive barrier (AWRB): This is attached directly to the building’s frame and is the last line of defense against air leakage and moisture intrusion. The AWRB may be permeable or impermeable to water vapor, depending on the climate.
• Exterior Insulation: This outer layer of insulation is capable of handling some moisture and drying without degrading or reducing its R-value. Depending on the building owner’s thermal requirements and targets, this layer may be supplemented. Also, Energy codes require different degrees of exterior wall thermal performance.
• Venting Profiles: There are several ventilation options available to help direct moisture away from the wall surfaces and to keep out pests.

The Perfect Wall

Technology advancements have also allowed modern construction to achieve the perfect wall, a complete, engineered system that performs better and saves money over the long term. The perfect wall contains all four building enclosure control layers:

• Air Control Layer – To limit the uncontrolled flow of air through the wall assembly, reducing condensation and energy loss.
• Water Penetration Control Layer – Barrier inbound of the cladding, flashed to the exterior, designed and installed to prevent liquid water from entering the wall cavity.
• Vapor Control Layer – Vapor permeable or impermeable per designer specification, controls the flow of water vapor from areas of high to low pressure, minimizing condensation.
• Thermal Control Layer – Insulation to significantly reduce thermal bridging.

Sto offers a wide range of wall systems, from prefabricated wall panels to EIFS with drainage, plus many more. From superior performance and sustainability to inspired aesthetics, your perfect wall is just a few clicks away with the Sto^® Wall Selector.

Material Science: The Next Generation of Building Products

The pace at which material science is advancing is ever-accelerating. Lightweight cladding is the next big thing for the construction industry. With lightweight cladding, it’s no longer necessary to use heavy materials such as masonry, concrete, metal panels, precast, porcelain, or even fiber cement to achieve the look of brick, wood, concrete, or metal. The benefits of lightweight cladding include:

• Smaller carbon footprint
• On-the-wall energy performance
• Authentic aesthetics
• Simpler and safer for construction crews
• Lower energy bills
• Near limitless design freedom for architects

StoCast, one of our most exciting and popular new products, is an example of this innovative new cladding. StoCast Wood is a resin cast product that can be applied to a variety of Sto wall systems to deliver a real wood aesthetic. StoCast Brick replicates the look of traditional brick and is available in 30 standard bricks or project-specific colors, patterns and textures.

The Future of Building Protection is Here

Building protection has come a long way since the days of mud and fur. At Sto, we are proud to be a leader in innovative, sustainable building solutions that enhance aesthetic value, durability and energy efficiency, addressing the evolving needs of modern construction.

As part of a comprehensive rainscreen system, StoVentec Render is tested, proven, and trusted from a single source supplier.

Finally, A Complete Rainscreen System

There are so many components to a rainscreen system that it can feel complex. But it doesn’t have to be overwhelming. StoVentec Render is unlike most rainscreen solutions. In addition to being one of the most advanced, thoroughly tested systems on the market, it can simplify life for the architect, the applicator, the general contractor, and the building owner.

The most apparent difference between StoVentec Render and other solutions is that StoVentec^® is a complete system, with all the components – including the air and water-resistive barrier, thermal insulation, sub-construction, carrier board, and a wide variety of architectural finishes, textures, shapes, and colors.

Since Sto manufactures all these components, coordination and construction are easier. After all, you are dealing with one company instead of four or five different suppliers. Plus, StoVentec Render is covered by a single 10-year system warranty.

StoVentec Render: An Ideal Blend of Art, Economics and Performance

StoVentec Render combines rainscreen technology with Sto’s well-known, tested, and trusted line of architectural finishes, including StoCast resin cast shapes and unique StoSignature options. Our beautiful finishes allow you to create a smooth, textured, or patterned surface.

These finishes, which also have waterproofing and fire-rating qualities, are applied directly onto the StoVentec Carrier Board- a lightweight, flexible, and impact-resistant glass composite board that can span up to 82 feet without architectural breaks.

The combination of the StoVentec Carrier Board and StoVentro sub-construction allows for the creation of unique curved surfaces, removing the barriers to the artistry of form and shape.

Designing your entire facade is easy with StoColor. The StoColor System is a unique planning tool for using color in architecture. It can be used with StoVentec to create customizable aesthetics. By integrating StoColor finishes and StoCast, you can make a one-of-a-kind exterior design.

To explore the possibilities, see the StoVentec Render Design Guide.

StoCast Looks So Real, It’s Unreal

Another design possibility is StoCast. The StoCast products are flexible, prefabricated resin-cast shapes that celebrate traditional facade textures while integrating enhanced performance functionality.

StoCast Wood features resin-cast wood grain planks that create an authentic wood appearance. Achieving the desired finish is easy when using any of the 25 standard colors available in StoColor Wood Stain.

Free of both dust and silica, StoCast Brick offers 30 standard bricks or project-specific colors, patterns, and textures. StoCast Brick is ideal when the project calls for a traditional or customized “classic” brick look.

Both products are more lightweight and durable than their traditional counterparts, minimizing time and energy in transportation and installation and allowing for greater conservation of natural material resources.

A Durable, Sustainable Solution

StoVentec Render is a high-quality system designed for durability. All system components working together will improve building performance significantly, saving short-term and long-term energy. StoVentec Render Rainscreen walls perform well because they effectively manage moisture by preventing most precipitation from entering the wall and allowing convective air movement within the air gap to promote drying.

All of this depends on an effective air barrier to keep outdoor air out and indoor air in. Sto AirSeal fluid-applied water-resistive barrier is vapor permeable, offers 500% elongation, meets the requirements of ASTM C1305 Low-Temperature Crack Bridging Test, and provides building code compliance confirmed by ICC-ESR 1233. It is suitable for all substrates, from porous lightweight CMU to gypsum and wood-based sheathing.

Insulation is also a critical component. StoVentec Render uses mineral wool, an effective, noncombustible insulation that can reduce sound by up to 10db.

Tested and Proven

Since the early 2000s, millions of square feet of StoVentec Rainscreen wall systems have been installed on countless buildings across Europe. What’s more, StoVentec Render is tested and proven. This outstanding system meets or exceeds all the following building codes and requirements:

• NFP285 (fire testing)

Buildings are imperfect. Whether it’s new construction or an existing building, they have crooked exterior walls/substrates or are smothered in layers of coating from previous renovations. While new buildings have the potential to have straight exterior walls, the requirements of those walls in the future are uncertain. How is the future uncertain? There are shifting weather patterns and more extreme weather events that buildings must endure. Building codes also evolve. New design trends can impact exterior walls as well. These things can force cladding changes that must be installed over the sub-construction. And that’s a few reasons why an adjustable sub-construction is a smart decision. We’ll get to the others, but first, let’s talk about what this future-friendly system looks like.

How Does an Adjustable Sub-Construction System Work

Imagine a comprehensive system of brackets, rails, fasteners, and other accessories that work together to create a framing system that can be adjusted as needed to make a perfectly flat, square surface to install the facade cladding. At Sto, that system is StoVentro. Part of our innovative StoVentec®Rainscreen® System, StoVentro absorbs both the wind loads and dead loads present on the facade. Alongside structural suitability, the design of the sub-construction incorporates corrosion resistance and a reduction in thermal bridging while also being quick and easy to install.

Installation Made Simple

The good news for general contractors: StoVentro is easy to install in three straightforward steps.

Align Brackets

First, you’ll want to align brackets to proper (loading design-specific) horizontal and vertical spacings. Anchor to structure with substrate-appropriate fasteners.

Align Vertical Profiles (T’s and L’s)

If cutting the rails, be sure to deburr the edges. Use clamps to temporarily secure vertical rails to the brackets. Install the first and last profiles on each facade plane, then use a horizontal reference line to align the remaining profiles. Or use a laser or spirit level to align the exterior axes (front flanges of the T and L profiles).

Fasten Profiles

Use StoVentro sub-construction screws to fasten the profiles to the brackets. Utilize oblong fastener slots on the small brackets for sliding point fastening and the circular holes on the large brackets for fixed point fastening. This allows the profiles to thermally expand and contract.

Now that the sub-construction is in (wow, that was easy!), let’s talk about the cladding.

Adaptable to Different Material Types and Thicknesses

We’ve mentioned how an adjustable sub-construction can turn imperfect walls into perfectly square walls. But what about the cladding that will, inevitably, sit atop this sub-construction? That system of brackets, rails, and fasteners all make for a very adaptable, flexible system. That means no matter what external cladding materials you use and how thick they may be, the sub-construction can accommodate it. That’s one of the primary purposes of the system. Who knows what future building design will look like? With an adaptable sub-construction system, you will be ready for what’s next.

Built for Design Flexibility and Originality

If you are building over an old wall without a sub-construction system, your cladding options are limited. But with a modern sub-construction system, the possibilities are unlimited. The StoVentro system serves as the foundation for all StoVentec systems, allowing for the use of glass, a wide variety of Sto architectural finishes, and masonry veneer. It is so adaptable that you can use virtually any cladding system, even one made by other manufacturers. The design possibilities are endless!

Improved Building Performance

We’ve covered several benefits of a sub-construction system, but there are a few significant benefits we haven’t yet covered. One critical benefit to building performance is that the StoVentro system allows for ventilation and drainage. Another advantage of an adjustable sub-construction system is that it can improve the thermal and acoustic performance of the building envelope. By incorporating an adjustable system, you can address any issues quickly and efficiently, minimizing “downtime” and ensuring consistent, maximum performance. Plus, the combination of the rainscreen and cladding systems used on top of the StoVentro system can help maximize energy efficiency by making space for exterior thermal insulation.

A Leader in Innovative, Sustainable Building Solutions

At Sto, we are focused on addressing the evolving needs of modern construction. We are committed to creating solutions that perform at the highest level and are sustainable. The StoVentro system is one of our most innovative systems. It is an easily installed, adjustable sub-construction that can compensate for existing walls or substrates that aren’t straight and make using multiple materials on the facade easier.

At Sto Corp., we admit we are a little obsessed with impact-resistant building materials. After all, the world can be a tough place—heat domes, drought, flash flooding, and woodpeckers. These persistent birds often cause unnecessary damage by pecking at the exterior of buildings.

Introducing Sto Strike Defense, an ultra-high impact resistance solution designed to protect EIFS (Exterior Insulation and Finish Systems) from blunt or sharp objects and mitigate damage caused by woodpeckers. We tapped (get it?) deep into our industry-leading innovation to develop a solution that’s easy to install and lives up to the promise of advanced protection. Sorry, woodpeckers.

Deterring Woodpeckers is Just the Beginning

Woodpeckers aren’t the only cause of blunt-force impacts. Punctures from vandalism and blunt and sharp objects are also a problem. Entryways, staircases, and lower sections are most susceptible to accidental impacts and punctures. Such damages can lead to water infiltration and system failures. Sto Strike Defense provides an additional layer of defense, preserving the look of the building and protecting the systems behind the cladding.

The Technology Behind the Product

Sto Strike Defense is a fortification option specifically engineered to offer outstanding impact and puncture resistance to new and existing EIFS. The key component of Sto Strike Defense is StoArmat Classic Plus, a patent-pending, organic, high-build acrylic plaster. This cement-free product means additional benefits of no efflorescence, less maintenance, and a smaller carbon footprint.

In restoration applications, fortification is achieved by embedding Sto Mesh in StoArmat Classic Plus over the existing EIFS. For new construction, the StoArmor Mat must be embedded in the basecoat along with the fortification layer.

Intelligent Solutions from an Industry Leader

Sto Corp. is the world’s leading innovator in claddings, air barriers, coatings, and restoration systems. So, it’s no surprise that we are developing impact-resistant solutions like Sto Strike Defense that help to improve building performance by reducing repairs and maintenance costs. But impact-resistant systems are only the beginning. Our portfolio includes special wall assemblies engineered to meet very particular design and performance requirements of the building enclosure and the ability to achieve a wide variety of aesthetic appearances using Sto textured finishes, Sto Specialty finishes, or StoCast prefabricated resin cast shapes.

Insulation Evolved

So, what exactly is GPS? GPS (graphite polystyrene) is a rigid thermal insulation material. The primary difference between GPS and traditional insulation products is that GPS insulating boards are thinner. In fact, they are up to 20% thinner than other rigid insulation boards. That means less material is required to achieve the same results. And the product itself is recyclable, making it more environmentally friendly.

What Makes the Sto GPS Insulation Unique?

It’s all about the graphite. Sto GPS Board is a rigid, graphite-enhanced, 100% closed-cell expanded polystyrene insulation board. We use graphite because it is the most stable form of carbon – safe and chemically inert. Plus, it reduces thermal conductivity and increases the R-value by as much as 25%.

Technically Speaking

So, how does the use of graphite and closed-cell construction impact performance? We’re glad you asked. It provides R4.7 per inch of thermal resistance at 75°F. In other words, our GPS Board enables you to achieve a higher R-value in thinner walls without the use of fluorocarbon blowing agents. Sto GPS Board complies with ASHRAE 90.1-2019 prescriptive continuous insulation requirements.

“Fluorocarbon Blowing Agents?”

It’s how some traditional polyurethane foam insulation panels are made. And some blowing agents are harmful to the environment. Sto GPS (and EPS) do not use blowing agents to achieve their thermal performance. As a result, the R-value is more stable than insulation that uses blowing agents, and they are better for the environment with no off gassing.

How Does a Thinner Board Affect Design?

Achieving a higher R-value in a thinner product gives design professionals new options for exterior wall configurations. Walls can be made thinner with equal thermal resistance, creating a larger interior for a given building footprint. Or wall thickness can remain the same, and thermal resistance can be substantially increased.

Another Sto Difference: Board Size

Sto GPS Board is available in larger sizes than most traditional panels and in various thicknesses. That means you’ll use fewer boards, and the boards are easier to work with. Plus, Sto GPS Board is installed using Sto TurboStick or Sto TurboStick Mini, so there are no mechanical fasteners, which means faster, easier installation and no thermal bridging.

Excels in Extreme Climates

The thermal resistance of the Sto GPS Board gets better as temperatures drop. It is rated at R4.7 per inch at 75°F per ASTM C578; at 40°F, it attains R4.9 per inch. In addition, the closed-cell design is moisture vapor semi-permeable. This allows a board in contact with water to dry out, helping preserve high insulation performance and facilitating moisture egress from wall systems.

Better for the Environment

As a result of the manufacturing method and the slimmer size of the panels, Sto GPS Board has excellent long-term R-value stability. With Sto GPS Board, very little additional material is needed, and the cost difference is negligible. The payoff is reduced building energy consumption, better building operating economics, and reduced emission of greenhouse gases. Did we mention that it’s also recyclable? Sto GPS insulation can be reused to make other products, so it never has to end up in a landfill.

Compatible with Sto’s Advanced Wall Systems

StoGPS Board is an integral part of our perfect wall, but it’s only the beginning. Sto GPS Board can be used as part of StoTherm^® ci GPS, StoTherm^® ci MVES, StoPowerwall^® ci, and StoPanel GPS ci.

Innovation, Inside and Out

We’ve talked about the innovation inside the walls, but what about the cladding and finishes on the outside? Sto GPS insulation works beautifully with StoCast Wood and StoCast Brick, which creates an authentic look while reducing costs, installation time, and the impact on our environment.

Where possible, having one comprehensive system from a single manufacturer surrounding the entire structure eliminates the risk of gaps and, as a result, exposure to the elements. Any perceived benefits from the multi-system approach aren’t worth the risk of potential wind and water damage. But what about all those components that need to work together? Sto has you covered.

The Components of the Building Envelope

Building envelope systems form the primary thermal barrier between the interior and exterior environments and include all the components of a building’s outer shell. A high-performing building envelope design should prevent air leaks and moisture intrusion through an exterior wall by applying continuous air and water-resistive barriers to manage water infiltration and accumulation. The building envelope includes all of the following:

• Above-grade exterior walls: structural and nonstructural
• Below-grade walls
• Fenestration: windows, doors, and metal/glass curtain walls
• Roofs
• Atria

The Benefits of a High-Quality Building Envelope

Successful application of a building envelope provides many benefits to a building:

• Moisture Control: Stops moisture infiltration by preventing condensation in the wall system to resist structurally damaging mildew and mold.
• Energy Efficiency: Prevents air infiltration through the wall, reducing energy use and costs
• Indoor Environmental Quality (IEQ): Creates comfortable, mold-free buildings, enhancing overall indoor air quality.
• Durability: Manages moisture and air infiltration in a building’s wall system to lower the risk of corrosion and decay and significantly reduce costly maintenance and repairs.
• Safety: Controls airborne pollutants, solar radiation, and the spread of smoke and fire.

The Climate Mobilization Act – Local Law 97 (LL97) was passed by the New York City Council and went into effect on November 15, 2019 as part of New York City’s Green New Deal. This legislation sets limits on greenhouse gas (GHG) emissions for nearly 50,000 of New York City’s largest buildings. At the same time, the Department of Buildings created the Office of Building Energy and Emissions Performance (OBEEP) to oversee the implementation and compliance of the NYC Local Law 97.

Building Emission Limits

In December 2022, the NYC Department of Buildings (DOB) set building emissions limits (carbon ft2) based on property type, size, and compliance year. Beginning in 2024, the law assigns emissions limits that reflect the variation in energy use between 60 different property types from the ENERGY STAR Portfolio Manager. The limits take effect over four compliance periods, from 2024 to 2049, with stricter requirements as time goes by and allows for a gradual reduction in a building’s carbon emissions.

Why NYC Adopted Local Law 97

Buildings generate over two-thirds of New York’s greenhouse gas emissions. Reducing greenhouse emissions will improve air quality, benefit human health and prevent economic losses due to lower agricultural yields, reduced labor productivity, and decreased industrial output.

By focusing LL97 on the city’s most prominent buildings, the Climate Mobilization Act predicts the following outcomes in New York City by 2030:

• Reduction in New York City’s overall emissions by 10 percent
• Lessening of the city’s dependency on fossil fuels
• Saving building owners money by reducing energy bills
• Removal of 6 million tons of greenhouse gas emissions is equivalent to taking 1.3 million cars off the road yearly
• Creation of 26,700 green jobs
• Lessening of the community’s exposure to harmful air pollution that causes respiratory illnesses
• Preventing 50 to 130 premature deaths annually
• Eliminating 150 hospital visits annually

Which Buildings Must Comply with Local Law 97?

Local Law 97 aims to reduce emissions produced by New York City’s buildings by 40 percent by 2030, and 80 percent by 2050. Local Law 97 applies to the following covered buildings, with some exceptions:

• Buildings with more than 25,000 gross ft2
• Two or more buildings on the same tax lot that together surpass 50,000 ft2
• Two or more buildings governed by the same condo association board of managers and together exceed 50,000 ft2. 

Buildings Exempt from NYC’s LL97

Local law exempts the following buildings from carbon emission limits:

• Industrial facility primarily used to generate electric power or steam
• Multi-family dwellings of 3 stories or lower, with no central HVAC or hot water system
• City buildings
• Non-profit hospitals and healthcare facilities
• New York Housing Authority’s housing developments or land
• Buildings classified as a group A-3 religious house of worship
• Rent regulated housing
• Real estate owned by a housing development fund company and organized by Article 11 of the private housing finance law and the business corporation law 
• Properties that participate in a project-based federal housing program

Affordable Housing Pathways

LL97 mandates that covered buildings with rent-regulated and/or affordable units should follow one of three pathways. The pathway depends on several factors, primarily based on the percentage of units in the building subject to rent regulation and if the units participate in a federal project-based housing program:

1. Prescriptive Pathway (Article 321): The pathway for buildings with 35 percent or more rent-regulated units or one or more units participating in a federal project-based housing program.

The Prescriptive Pathway (Article 321) mandates that by 2024, the buildings must achieve emissions below the applicable 2030 limits or prove full implementation of relevant Prescriptive Energy Conservation Measures. In addition, building owners must file a one-time report by May 2025.

2. 2026 Compliance Pathway: The pathway for buildings with between one and 35 percent rent-regulated units.

The 2026 Compliance Pathway mandates that by 2026, buildings must meet emission limits or face penalties. In addition, building owners must file annual reports starting May 2027.

3. 2035 Compliance Pathway: The pathway for Mitchell-Lama buildings with no federal project-based housing program or rent-regulated units. The building can have one plus income-restricted units through certain loans, grants, and real property tax benefits.

The 2035 Compliance Pathway mandates that buildings must meet emission limits starting in 2035 or face penalties. Building owners must file annual reports beginning May 2036.

Impact of LL97

The cost to upgrade a building’s energy efficiency in compliance with LL97 may challenge some building owners. However, the law will improve energy management and provide many long-lasting advantages for businesses, properties, and tenants:

• Enhances tenant satisfaction and lessens turnover by improving comfort and keeping rents affordable
• Increases the marketability and value of properties by installing high-performance equipment
• Lowers the building’s carbon footprint and contributes to a healthier, cleaner community
• Improves the building’s bottom line by lessening operating expenses

When Does Compliance to LL97 Start?

Starting January 1, 2024, building owners for the 60 different covered building types must comply with the first round of carbon emission limits. Compliance with emission standards will change over time until it reaches zero in 2050.

In addition, beginning May 1, 2025, building owners must file an annual report with the Office of Building Energy and Emissions Performance (OBEEP) detailing their yearly greenhouse gas emissions. A Registered Design Professional, like a professional engineer or registered architect, must submit the report.

Penalties for Non-Compliance to LL97

Building owners not complying with emission limits and reporting can face civil penalties and fines: 

• If a building exceeds its annual emission limit, the fine can amount to the difference between the building emissions limit and the LL97 emission limit, multiplied by $268.
• Not submitting your building’s annual emissions report can result in a civil penalty of $0.50 per gross ft2/month.
• Making a false statement can result in a Misdemeanor with a fine of up to $500K and prison for up to 30 days.

As with most extensive legislation, the NYC Department of Buildings has continued to clarify and define requirements to be in compliance with Local Law 97, including the newest packaging of rules from December 18, 2023.​

Timeline and Targets For LL97

Carbon emissions caps will become stricter over a series of compliance periods: 2024-2029, 2030-2034, 2035-2039, 2040-2049, and 2050 – outward.

December 31, 2024: The Prescriptive Pathway for regulated and affordable units mandates that building owners take specific energy conservation measures like upgrading lighting, weatherization, and air sealing or demonstrate compliance with 2030 emissions limits.

January 2024: Limited annual emissions for covered buildings for 2024 to 2029 begins. However, types of affordable housing and buildings (under the law’s Article 321 prescriptive path) have altered or delayed requirements. 

May 1, 2025: Building owners must submit their first detailed, compliance buildings emission report.

June 2025: City-owned buildings must achieve an emissions reduction target of 40 percent below fiscal year 2006.

January 1, 2026: OBEEP must submit the first annual compliance report on covered buildings to the mayor. Buildings with at least one, but no more than 35 percent rent-regulated units must begin complying with carbon emission limits. 

January 2030: Covered buildings must comply with new stricter emissions limits for calendar years 2030 – 2034. Also, after 2030, a building must lower its carbon associated with electricity use. In addition, the NYCHA must reduce greenhouse gas emissions by 40 percent below 2005 levels.

June 2030: City-owned buildings must achieve an emissions reduction target of 50 percent below fiscal year 2006.

January 2035: Three significant mandates begin in 2035:

1. Covered buildings must comply with new stricter emissions limits for calendar years 2035 – 2039.
2. A building must lower its carbon associated with electricity use in line with projected renewable energy deployment in NYS after 2035.
3. Income-restricted housing, like Mitchell Lama rentals, must begin complying with carbon emissions limits.

January 2050: All covered buildings must show compliance with an emission factor of 0.00. In addition, NYCHA must attempt to lower greenhouse gas emissions 80 percent below 2005 levels.

How To Prepare for Local Law 97

Ensuring that your building will meet carbon emission limits in 2024 requires evaluating your building’s status, improving its energy efficiency by applying new sustainable technologies, and educating yourself on carbon emissions.

Determine Your Building Current Energy Usage and Carbon Emissions

Determining your building’s current emissions compared to the 2024 carbon emission limits will help identify areas of improvement and prepare for meeting LL97 targets.

Building owners can measure and track greenhouse emissions as well as energy and water consumption using the ENERGY STAR Portfolio Manager® online tool, with just your energy bills and basic information about your building. 

A design professional (energy auditor) can help evaluate your building’s energy consumption, suggest ways to improve its energy efficiency, and navigate the complex reporting requirements of Local Law 97.

Begin Reducing Your Building Energy Use

Lessening your building’s energy use within can help prepare for LL97:

Install Sensors

Installing sensors can optimize a room’s lights based on occupancy and more efficiently control building comfort by enabling improved HVAC zone controls.

Replace Windows and Doors 

Installing ENERGY STAR-storm skylights, windows, and doors can lessen heat loss by 25 to 50 percent. In addition, automatically darkening windows can control glare and brightness from direct sunlight. Shades and louvers can block out the summer’s heat, but can let the warmth in during the cold months.

Energy-Efficient Lighting

Lighting contributes up to ten percent of a building’s annual electricity costs. Installing controls like dimmers, timers, or photocells that turn unused lights off and energy-efficient lighting, like halogen incandescent, light-emitting diodes (LEDs), and compact fluorescent lamps (CFLs) will lessen energy use.

High-Efficiency Ventilation Systems and HVAC 

A building’s heating and cooling system accounts for 34 percent of the structure’s energy use; therefore, consider replacing an old, inefficient HVAC system with a properly installed high-efficiency heating and cooling system. In addition, an energy recovery ventilation system can also manage ventilation and lower energy loss by transferring energy from outgoing conditioned, polluted air to fresh incoming air. 

Upgrade the Building Envelope

Upgrading the building envelope to include continuous insulation, an air and water-resistive barrier, and a durable, protective facade will create an energy-efficient, code-compliant, durable, and attractive commercial building that can contribute significantly towards achieving LL97 carbon emission limits.

Sto Corp. offers a variety of energy-efficient, code-compliant building envelope solutions that include continuous insulation and air and water-resistive barriers applicable for renovation projects and new construction.

Vapor-permeable or impermeable liquid-applied AWRB materials form a membrane upon drying and curing that bonds to the exterior sheathing without fasteners. Liquid-applied AWRB membranes can be used behind any cladding, including: exterior insulation and finish systems (EIFS), glass panels (opaque), fiber cement, brick, stone, stucco, and metal panels. Liquid -applied materials can be used as wall membranes as well as flashings around rough openings, penetrations, etc.

AWRB Performance Requirements

Building codes mandate the performance requirements for AWRB products. They specify that AWRB materials must comply with the 2021 International Building Code (IBC 1402.2) requirements for water resistance and vapor permeability and the 2018 International Residential Code for water resistance (IRC R703.1.1). 

Applicators can choose from several qualifying AWRB materials, including self-adhered membranes, concrete, spray foam, building wraps, integrated sheathings, sheet goods, thermal insulation boards, and liquid-applied membranes. Crucial components of a high-quality AWRB include high tear strength, durability, ultraviolet resistance, and straightforward installation.

In addition, accessory materials (reinforcing mesh, tapes, sealants, sheet goods, elastomeric materials, self-adhered membranes, and foam products) can be used in conjunction with liquid-applied AWRB to provide continuity of air or water resistance. 

Contact the professionals at Sto today for guidance and assistance in choosing the best liquid AWRB and the right accessories to integrate to achieve a tight building envelope. 

Benefits of Liquid-Applied AWRB Membranes

Liquid-applied air and water-resistive barriers provide many advantages that save time and money and help preserve the health and integrity of a building:

Quick Application

A qualified installer can quickly roll or spray the air and water-resistive barrier membrane on the wall to save both time and money. In addition, a spray-applied vapor barrier does not need a primer, which further saves time.

Durable

A liquid-applied AWRB barrier will not lose its integrity when exposed to outside elements during and after construction. Check with the manufacturer’s recommendation for length of exposure.

Permits Complex Detailing

A liquid-applied AWRB efficiently adheres to and waterproofs various wall conditions (e.g., detailed wall openings, penetrations, fasteners, and repair locations), conforms to uneven substrates, and adapts to complex architectural substrate geometry and is the ideal choice when waterproofing critical details.

In contrast, sheet-applied air and moisture barriers need cutting, folding, lapping, and sealing.

Moisture Barrier

When applied at the proper thickness, a liquid-applied vapor barrier produces a seamless moisture barrier by limiting installation errors that can cause lap joints, tears, and holes.

Air Barrier

A liquid-applied AWRB stops air leakage, reduces energy costs and condensation, and improves occupant comfort.

Rainwater Barrier

Liquid-applied barriers for pressure-equalized or pressure-moderated wall design will lower the risk of rainwater penetration through the wall system.

Wind Barrier

A liquid-applied AWRB provides structural and full adherence for rigidity and stability against extreme wind events.

Reduces Repairs

A liquid-applied AWRB membrane protects the sheathing and rough openings from weather damage during and after construction, which reduces repair and replacement costs.

Safe

Safe to use, V.O.C.-compliant AWRB offers easy cleanup.

A tight building envelope relies on keeping it air and weather-tight. The use of a quality sealant should be used as perimeter weather seal around windows, doors, and other through wall penetrations, thermal expansion and contraction joints, and control joints to prevent air and moisture infiltration. Sto’s sealant, StoSeal STPE Sealant provides a high-movement, low-odor, non-sag sealant for use in new construction or renovation projects from a single manufacturer.

Why Are Sealants Needed?

EIFS systems, like all wall claddings, require sealants around doors, windows, service openings, and between dissimilar materials to help ensure a water-resistant and airtight building envelope. Sealants also absorb thermal expansion and contraction.

Sealant Issues with EIFS Cladding

Inadequate application or missing sealants to EIFS or any claddings will provide a path for unwanted air and moisture into EIFS cladding that can lead to premature deterioration and failure of the EIFS finish coat, which typically is not covered by manufacturers’ warranties.

Failures commonly occur when the sealant is applied to the finish coat instead of the mesh-reinforced base coat, the sealant is not regularly inspected after reaching its life expectancy, commonly five to ten years, if the sealant was applied over a dirty substrate, the wrong modulus was used, and more.

Properly Sealing EIFS Projects

The airtightness of the EIFS system’s joints depends on the sealant’s adhesion, durability, and compatibility with the EIFS. Therefore, when constructing an EIFS system, it is vital to use a high-quality sealant, like StoSeal STPE Sealant. In addition, applicators must follow the manufacturer’s application instructions to achieve the EIFS project’s performance requirements and avoid sealant failure. 

Why Use STPE Sealants for EIFS Projects

High-performing EIFS sealants offer flexibility, durability, sustainability, and ease of application. The building industry utilizes several sealants, including polyurethane, silicone, and Silyl Terminated Polyether (STPE).

Polyurethane and silicone lack characteristics that impact their effectiveness and durability: 

• Polyurethane sealants lack adequate weather resistance.
• Silicone’s bonding properties may fail under strong shear forces.
• Non-sustainable, non-recyclable polyurethane and silicone break into unhealthy chemicals if heated past their maximum operating temperatures. 

Fortunately, sustainable and fast-curing STPE sealants combine silicone’s weather resistance and polyurethane’s strength to produce a long-lasting sealant with superior adhesion, strength, and flexibility. Fast-curing STPE sealants also maintain their color by minimizing exposure to debris and dust, which can cling to the sealant.

Silyl Terminated Polyether (STPE) Sealants for EIFS Projects

A tight building envelope keeps outside elements (e.g. air and moisture) from infiltrating a structure. Correctly applying a high-performing STPE joint sealant is a vital step towards weatherproofing an EIFS building’s exterior and protecting its health and integrity. 

Silyl Terminated Polyether (STPE) sealant technology provides several superior high-performance features that will contribute to a long-lasting, energy-efficient EIFS system:

Durable and long-lasting STPE sealants for EIFS

• Durable and Weather Resistant: STPE sealants perform well in most weather conditions and at low temperatures (unlike polyurethane sealants) with little adhesion failures, cracking, splitting, or discoloration.
• Flexibility: STPE sealants’ elongation characteristics can endure structural movement and withstand substrate vibrations or oscillations more effectively than silicone sealants.
• UV Resistant: STPE sealants will not crack or yellow after extended periods of UV-light exposure, unlike polyurethane sealants.
• Non-Reactive: STPE sealants will not corrode or oxidize metals.
• Storage Stability: STPE sealants have an excellent shelf life when not exposed to moisture.
• Cold Resistant: STPE sealants retain their properties to -50°F (-45°C).
• Adhesion: STPE sealants have excellent cohesive strength that adheres more effectively to many substrates, like metals, concrete, wood, plastics, and ceramics, compared to polyurethane and silicone sealants.

STPE sealants for EIFS Ease of Application

STPE sealants may not require priming on most substrates and can create a continuous smooth surface. In addition, you can paint STPE sealants after 24 hours. 

Environmentally-Friendly

Recyclable STPE products contain extremely low or no VOCs, unlike other sealants prone to off-gassing, like polyurethane and silicone, which will break into unhealthy chemicals if heated past their maximum operating temperatures. 

StoSeal STPE High-Quality, Versatile Adhesive Sealant

StoSeal STPE Sealant from Sto® Corp. is a high-performing, low-odor, isocyanate-free, one-part hybrid sealant with a VOC content of 8 grams per liter. It is a durable, flexible, low-modulus, non-sag sealant with excellent moisture and weathering resistance.

combines polyurethane’s strength and silicone’s weather resistance to provide an all-in-one solution for above-grade, vertical building restoration (and new opaque wall) applications. StoSeal STPE Sealant will contribute significantly to the long-term weather resistance of the building envelope.

Building Restoration

Designing a code-complaint building restoration project with an airtight building envelope requires correctly applying a quality sealant. A high-performing, elastomeric, flexible sealant prevents the passage of liquids, light, or gasses between two materials despite movement between those components.

It’s important to know that the quality of the sealant you choose for a building restoration project can affect its service life and, ultimately, the long-term airtightness and weatherproofing performance of the building’s envelope.

Building Restoration Sealant 

Sealant is used to seal, block or close gaps between building materials to prevent fluids, air and other substances from passing through. Building restoration projects often require the removal and replacement of sealant. Builders can use it for numerous applications, including:

• Expansion joints to allow for thermal movement of the building
• Air seals at interior or exterior joints and seams to provide air barrier continuity
• Panel-to-panel joints between precast, metal frame, and other prefabricated wall construction
• Control joints
• Deflection joints sealant at floor lines
• As a bedding sealant for flashing, flanged windows, and related applications
• Perimeter weather seals around doors, windows, scuppers, and other through-wall penetrations
• Perimeter weather seals around fixture attachments

Specifying the proper sealant will ensure the sealant performs as intended and reaches its maximum service life.  Proper design and installation of the sealant will maximize the building envelope’s service life and limit the potential need for costly repairs which could result from water intrusion. A properly performing sealant also prevents excessive air movement which affects occupant comfort and contributes to energy costs during the building’s service life.

StoSeal STPE Sealant: Your All-in-One Solution for Building Restoration

Applying a high-performing sealant for building restoration, like StoSeal STPE (silyl terminated polyether) sealant, will maintain a positive seal between the joint opening’s substrates, and provide long-term resistance against the passage of heat, light, sound, air, rain, snow, wind, odor, dust, and chemical and biological contaminants. It will also protect against the damaging effects of UV rays, thermal cycles, moisture, and structural movement.

StoSeal STPE Sealant combines the strength of polyurethane and the weather resistance of silicone to create a long-lasting weatherproofing sealant with superior adhesion, strength, and flexibility. StoSeal STPE Sealant bonds to most construction materials (cement, stucco, masonry, stone, concrete, wood, common metals and fiber cement). 

StoSeal STPE Sealant’s superior adhesive properties work effectively with StoVentec®, StoTherm® ci, StoPowerwall®, and StoQuik® exterior wall systems and with StoGuard® air- and water-resistive barrier systems for above-grade, vertical building restoration (and new opaque wall) applications.

• Quality-built and installed EIFS, like StoTherm® ci Wall Systems, contain continuous insulation that minimizes thermal bridging and a fluid-applied moisture and water-resistive barrier to create higher-performing buildings with less energy consumption, and also contains a drainage plane.
• Durable EIFS also complies with NFPA 285 (referenced in 2021 IBC Section 1403.5) to minimize fire spread, vertically and horizontally.
• EIFS offers numerous aesthetic choices and design flexibility.

Outdated ideas about EIFS, however, make some in the building community question the validity of modern EIFS systems as trusted and proven building products. These outdated attitudes may also affect the ability of building owners and contractors to get EIFS insurance.

Myths About EIFS Systems and Understanding Modern Systems

Misconceptions about EIFS primarily stem from issues that occurred over 30 years ago when EIFS systems were called Barrier EIFS. Modern (drainable) EIFS has proven to be a moisture-resistant, low-maintenance, lightweight, inexpensive, durable, and energy-efficient exterior wall cladding system. 

NOTE: The long-term success of an EIFS system requires an experienced, qualified installer who follows the manufacturer’s instructions. As with any wall system, correct design, detailing and installation is critical to the longevity of an external cladding solution.

Myth 1: EIFS does not drain water, which leads to moisture issues – False.

Barrier EIFS

Early EIFS was face-sealed (barrier) EIFS, with an insulation board fastened to the structural wall surface, typically made of gypsum. Unfortunately, barrier EIFS did not include the capability to drain water that may get into the wall system. The lack of drainage and the use of moisture-sensitive sheathing (such as wood-based) made buildings and homes built with barrier EIFS more prone to rot, mold, and insect problems. 

Development of Drainage EIFS

By the mid-1990s, in response to these problems, the International Conference of Building Officials (ICBO) and EIFS Industry Members Association (EIMA) implemented tighter requirements to stop moisture issues in EIFS. The requirements led to the development of drainable EIFS. 

Drainable EIFS has a secondary moisture barrier and a drainage plane that allows water to escape, created by the ribbons of adhesive used to adhere the insulation. This drainage plane significantly reduces the moisture issues with EIFS. Furthermore, the EIFS insulation thickness should prevent the interior air from reaching the dew point, to minimize condensation within the wall system.

The International Building Code (IBC) recognizes drainable EIFS as an allowable building material and also mandates the application of a water-resistive barrier to EIFS. The IBC mandates the application of a water-resistive barrier to EIFS, like Sto’s StoGuard family of products.  In addition, drainage EIFS creates an energy-efficient wall system that meets the requirements of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers ASHRAE 90.1.

Myth 2: EIFS isn’t as good as traditional stucco – False.

Grand Concourse Academy, Bronx, New York, USA

Traditional stucco and EIFS both create an aesthetically pleasing, long-lasting exterior facade. Both also offer about 70 percent ROI.

• Traditional stucco assemblies are mechanically fastened and include natural ingredients, such as Portland cement, lime and sand basecoats (called Scratch & Brown coats) with acrylic or cementitious finishes. These assemblies also use metal laths and weigh between 10-12 lbs/ft2.
• Drainable EIFS includes an air and water-resistive barrier, adhesive, continuous insulation, fiberglass mesh, basecoat, primer and finish. EIFS is approximately eighty percent lighter than traditional stucco at about 2 lbs/ft2 and is adhered to the substrate in the majority of cases.
• EIFS includes synthetic materials that are applied in coats over rigid foam insulation, a fiberglass mesh, and an acrylic finish, which creates a product 80 percent lighter than traditional stucco.

EIFS vs. Traditional Stucco

• Lightweight EIFS offers more flexibility, durability, and energy efficiency (R-value between 4 and 5.6) compared to traditional stucco. 
• Low-maintenance EIFS only requires regular cleaning, while traditional stucco often needs patching, caulking, and repainting.
• EIFS resists cracking, while traditional stucco being cement-based typically will have hairline cracks.

Myth 3: Builders only use EIFS on low-cost projects – False.

Lido Beach Towers, Long Island, NY, USA

Modern, drainable EIFS can accommodate all aesthetic and performance needs for new and retrofit construction, to help achieve superior design performance, flexibility, and sustainability levels. Architects and builders can use drainable EIFS for institutional buildings, distinctive hospitality structures, and homes – from high-end to low-cost projects.

Myth 4: EIFS is high maintenance and lacks durability – False

Fairfax City Net Zero Home

EIFS offers several low-maintenance and durable features:

• Simple to clean, EIFS requires only a low-pressure wash and a manufacturer-approved detergent.
• Advanced technology in finishes has allowed for the creation of self-cleaning finishes like Stolit Lotusan , making a more sustainable and longer-lasting facade.
• Durable EIFS resists cracks and crumbling resulting from shifting foundations, thermal expansion, or freeze/thaw cycles. 
• The design and use of a high-impact mesh with EIFS creates a durable, high-impact facade.
• Drainable EIFS allows water to escape, to prevent structurally damaging mold growth.

Myth 5: EIFS is combustible – False

Because EIFS most commonly uses combustible foam plastic insulation, the systems are subjected and pass industry mandated standard test for ignitability, fire resistance, intermediate multi-story, and flame spread tests

• Fire-resistant EIFS passes major tests required by building codes for:
• Ignitability (NFPA 268)
• Fire resistance (ASTM E119)
• Intermediate multi-story fire test (NFPA 285)
• Full-scale multi-story, corner test (ANSI FM 4880). 

Myth 6: EIFS lacks aesthetic appeal – False

The Greenhouse Dispensary – Skokie, Illinois, USA

EIFS comes in nearly any color, texture or aesthetic including brick, wood, granite, stone, concrete, stucco and more. In addition, the use of an EIFS system easily allows for the use of multiple aesthetics without concern for transition between materials.

Understanding the features and benefits of each of the different insulations will help you choose the best high-performing product for your building project.

Graphite Polystyrene Insulation

Manufacturers produce graphite polystyrene insulation (GPS) like EPS, but with the infusion of high-purity graphite particles into the polystyrene beads, which creates Neopor beads. Neopor gives GPS insulation a dark gray appearance and a greater R-value (4.7) than traditional EPS insulation products. Builders can use GPS insulation on wood or steel frame construction.

Benefits and Features of GPS Insulation

• Increased Thermal Resistance: The graphite particles reflect and absorb radiant energy, which slows heat transfer and produces 18 percent more insulation capacity than EPS. 
• Increased Board Strength and Flexibility: Manufacturers laminate the foam with a reflective film, which increases its strength and flexibility.
• Moisture Resistance: The reflective, micro-perforated laminated surfaces give the panel a high water vapor permeance (perm rating of up to 5.0), which reduces the chance of trapped moisture. 
• Improved Job Site Efficiency: The larger panels and laminated film enhance job site efficiency and lessen labor costs.
• Design Flexibility: Manufacturers can form GP into many different shapes during manufacturing.

Sto GPS Board

Builders and architects can use Sto GPS Board in StoTherm® ci GPS and StoPowerwall® ci systems. It offers the following benefits and features:

• Energy Efficiency: Sto GPS Board provides continuous exterior insulation for reduced energy consumption and cost. The higher R-value than standard EPS allows for thinner wall sections.
• Sustainable: Sto GPS has lower global warming and zero ozone depletion potential due to their manufacturing process not using fluorocarbon-blowing agents (HFC, HCFC, or CFC). Recyclable GPS boards limit their environmental impact.
• Moisture Resistance: The water vapor semi-permeable of Sto GPS Board aids in drying water in walls.

Extruded Polystyrene (XPS) Insulation

Extruded polystyrene offers closed-cell insulation for interior and exterior walls for new construction and remodeling. The manufacturing of XPS insulation involves combining polystyrene crystals with additives and a gas-blowing agent. An extruding machine then mixes and melts the mixture into a thick liquid before processing it through a die. The die expands the liquid into foam, then shapes and trims it into rectangular or standard square boards. 

Benefits and Features of XPS Insulation

XPS High Compressive Resistance

The high compressive strength (15-100 psi) of XPS insulation can withstand high pressure, so that it is able to withstand 6,144 lbs ft2 with a maximum deformation of 10 percent. 

Sustainable

• Recyclable: 100-percent recyclable, which allows manufacturers to melt and reform the thermoplastic polystyrene resin into new XPS foam insulation.
• Energy-Efficient: XPS closed cell insulation gives it a high thermal resistance value to provide an R-value of 4.6 and 5.0, depending on their density, which makes it extremely energy efficient, to save energy in buildings and reduce CO2 emissions. 

Moisture-Resistant

• Moisture-resistant XPS has an absorption rate of 0.3 percent to resist moisture infiltration during and after application. XPS insulation offers freeze-thaw resistance to protect the insulation’s thermal performance and to prevent damaging and unhealthy mold. The low permeability makes it perfect for laundry rooms and other high-moisture spaces. 

Straightforward to Install 

Simple to apply, lightweight XPS insulation does not irritate the worker’s skin.

StoTherm® ci XPS

Builders and architects can use StoTherm® ci XPS in residential or commercial wall construction where energy efficiency, superior aesthetics, and air and moisture control are essential in the climate extremes of North America. StoTherm® ci XPS is an EIFS with drainage and continuous insulation wall system that integrates the StoGuard® air and water-resistive barrier, XPS insulation, and drainage to produce the following benefits and features:

• Energy-Efficiency: StoTherm®ci XPS continuous exterior insulation achieves R-5 per inch with no mechanical fasteners to lower cooling and heating costs.
• Fast Installation: StoTherm®ci XPS provides quick-set adhesive, with no mechanical fasteners, decreasing thermal bridging.
• Moisture Resistance: StoTherm®ci XPS’s continuous air and water-resistive barrier protects against mold and moisture issues.
• Code Compliance: Fully tested building code compliant StoTherm®ci XPS assembly is ICC-ES listed and evaluated.

Expanded Polystyrene (EPS) Insulation 

Lightweight expanded polystyrene (EPS) foam is a rigid, closed-cell wall insulation. EPS manufacturing involves expanding raw polystyrene beads with steam up to 50 times their volume. The beads go into a mold where steam and pentane further expand them to form a rectangular block. 

Benefits and Features of EPS Insulation

High Compressive Strength

The compressive strength of EPS insulation ranges between 10 – 60 psi that increases with density. 

The high compressive strength provides:

• Thickness recovery after excessive construction load exposures.
• Absorption of substrate irregularities.
• Absorption of the substrate and facing movement due to structural deflections and temperature changes.
• Sufficient subgrade reaction for effective load distribution.

Sustainable

• EPS does not contain toxic ozone chemicals like formaldehyde, hydrochlorofluorocarbon (HCFC), hydrofluorocarbon (HFC), and chlorofluorocarbon (CFC). 
• EPS has a thermal resistant R-value of 3.6 to 4.2, which saves energy and money.
• You can recycle EPS.  

Moisture-Resistant

• EPS boards are available in several densities to meet specific project needs, from 0.75 to 2.0 psi. 
• The tightly packed cells stop voids, contributing to EPS’s moisture resistance and making it suitable for wet environments. 

Installation Benefits

• EPS provides installation versatility by cutting quickly and accommodating unfinished interior and exterior walls for new construction and retrofits. 
• EPS is lightweight and simple to apply.

Sto EPS Insulation Board

Builders can use StoTherm® ci in residential or commercial wall construction where energy efficiency, superior aesthetics, and moisture and air control are crucial.

Rigid cellular Sto EPS Insulation Board offers several benefits and features for use in StoTherm® ci Wall Systems, an EIFS with drainage continuous insulation wall system.

•  Aesthetic Flexibility: Workers can easily cut, score, shape, and rasp lightweight Sto EPS insulation board.

• Long Lasting: Fully tested for fire exposure and durability in StoTherm® ci Systems.
• Code Compliance: Made by licensed Sto EPS Insulation Board molders per ASTM E2430 and ASTM C578 requirements for Type 1 EPS. 

Mineral Wool Insulation 

Mineral wool continuous insulation contributes to energy-efficient building design and non-combustible construction. Manufacturers typically use steel by-products (blast furnace slag) made of spent iron ore and limestone to make mineral wool. 

Manufacturers melt slag and rock in cupola furnaces at over 2,600℉ (1426°C), then spin the molten lava into fibers using high-speed spinning wheels and compressed air. The manufacturing process produces mineral wool fibers that can withstand high temperatures, which gives them excellent fire-resistant properties. Builders can apply mineral wool continuous insulation behind non-combustible and combustible cladding types ranging from glass panels (opaque), EIFS, masonry veneer, resin cast shapes, metal panels, and fiber cement.

Benefits and Features of Mineral Wool

• Non-Combustible: Mineral wool insulation will not burn or release hot gasses and harmful smoke during a fire, which makes it a superior choice for multistory construction. Mineral wool in cavity walls and open-joint facade systems can significantly minimize fire spread across a building’s exterior wall surfaces.

The ASTM E119 test determines the fire performance of building materials based on fire temperature and time. It illustrates that mineral wool remains intact after five hours and temperatures over 2,000℉ (1093°C). 

• Energy Efficient: Mineral wool insulation, with an R-value of 4.3 per inch, easily meets the specified R-value requirements of the ASHRAE 90.1 to prevent thermal bridging and create an effective R-value in a wall system. In addition, moisture exposure will not diminish mineral wool’s R-value, and declining temperatures cause mineral wool’s thermal conductivity to decrease, which enhances its R-value. 

• Moisture Resistance: The engineering of mineral wool repels and drains moisture in continuous insulation applications. The design of mineral wool can handle driving rain, condensation, and other moisture on the wall system. 

• Permeable: Air and vapor-permeable mineral wool CI (perm of 50) permits condensation/moisture/water within the wall cavity to dry towards the outside.

• Sustainable: Using slag allows mineral wool to achieve one of the industry’s highest recycled contents, which minimizes its environmental impact. After one month of use, one pound of mineral wool insulation saves the amount of energy used in its manufacturing.

• Sound Attenuation: Mineral wool products provide sound attenuation by absorbing and blocking sound between partition walls and floor/ceiling applications to enhance the indoor environmental quality for the structure’s occupants.

• Durability: Durable mineral wool repels water and resists UV rays, ice, rain, sleet, snow, and other weather-related events. 

StoTherm® ci Mineral Wool Insulation

StoTherm® ci Mineral incorporates a high density non-combustible continuous exterior insulation and a continuous air and water-resistive barrier with Sto high-performance finishes to produce an advanced wall cladding system.

The post Insulation Comparison Features and Benefits: A Comprehensive Look at GPS, XPS, EPS and Mineral Wool in Exterior Facades appeared first on Sto Corp..

In 2000, the International Code Council (ICC) developed the International Energy Conservation Code (IECC). The purpose of the IECC is to establish the minimum design and construction energy efficiency requirements for renovated and new buildings. Between 2006 and 2021, the IECC increased its efficiency requirements by about 40 percent – an average of 8 percent per cycle.

The IECC uses ASHRAE 90.1 (the minimum requirements for energy-efficient buildings, except for low-rise residential buildings) as the ICC referenced standard for energy-efficiency. The ICC Referenced Standards Guide is an industry agreement of the level of performance in the designing, manufacturing, testing, and installing of materials, products, or assemblies. ICC Referenced Standards only become law once a jurisdiction references them in an I-Code.

Local and State Authorities Mandate Regional Building Codes

Local and state jurisdictions set energy building codes for their regions; however, most refer to and adopt the codes set by the commercial and residential IECC. States and municipalities depend on the IECC because of the cost and complexity of developing building codes and standards. All states and the District of Columbia have adopted the IECC, and adapted them to fit their local construction practices, climate, and geography.

IECC Commercial and Residential Air Barrier Building Codes

The ICC updates the IECC every three years. The newest version was published in 2021 and includes air barrier standards for commercial and residential buildings.

Testing and Performance Requirements for Air Barriers

Air barrier materials must achieve air permeance (air that permeates a material) no more than 0.02 L/(s·m²) at a pressure difference of 75 Pa (0.004 cfm/ft2 at a pressure difference of 1.56 lb/ft2 ) when tested, following ASTM E2178.

Air Barrier Application to Commercial Buildings

Section C402.5.1 of the 2021 IBC states, “A continuous air barrier shall be provided through the building thermal envelope. The continuous air barriers shall be located on the inside or outside of the building thermal envelope, located within the assemblies composing the building thermal envelope, or any combination thereof.” There is one exception: air barriers are not required in buildings located in Climate Zone 2B.

https://basc.pnnl.gov/images/iecc-climate-zone-map

Additionally, the air barrier must comply with Sections C402.5.1.1 and C402.5.1.2:

Section 402.5.1.1

The continuous air barrier shall be constructed to comply with the following:

• The air barrier shall be continuous for all assemblies that are the thermal envelope of the building and across the joints and assemblies.

• Air barrier joints and seams shall be sealed, including sealing transitions in places and changes in materials. The joints and seals shall be securely installed in or on the joint for its entire length so as not to dislodge, loose or otherwise impair it’s ability to resist positive and negative pressure from wind, stack effect and mechanical ventilation. 

• Penetrations of the air barrier shall be caulked, gasket or otherwise sealed in a manner compatible with the construction materials and location. Sealing shall allow for expansion, contraction and mechanical vibration. Joints and seams associated with penetrations shall be sealed in the same manner or taped. Sealing materials shall be securely installed around the penetration so as not to dislodge, loose or otherwise impair the penetrations’ ability to resist positive and negative pressure from wind, stack effect and mechanical ventilation. Sealing of concealed fire sprinklers, where required, shall be in a manner that is recommended by the manufacturer. Caulking or other adhesive sealants shall not be used to fill voids between fire sprinkler cover plates and walls or ceilings.

• Recessed lighting fixtures shall comply with Section C402.5.10. Where similar objects are installed that penetrate the air barrier, provisions shall be made to maintain the integrity of the air barrier.

Section 402.5.1.2

A continuous air barrier for the opaque building envelope shall comply with the following:

1. Buildings or portions of buildings, including Group R and I occupancies, shall meet the provisions of Sections C402.5.2.

Exception: Buildings in Climate Zones 2B, 3C and 5C 

2. Buildings or portions of buildings other than Group R and I occupancies shall meet the provisions of Section C402.5.3

Exceptions: 1. Buildings in Climate Zones 2B, 3B, 3C, and 5C. 2. Buildings larger than 5000 square feet (464.5 m2) floor area in Climate Zones 0B, 1, 2A, 4B, and 4C. 3. Buildings between 5,000 square feet (464.5 m2) and 50,000 square feet (4645 m2) floor area in Climate Zones OA, 3A and 5B.

3. Buildings or portions of buildings that do not complete air barrier testing shall meet the provisions of Section C402.5.1.3 or C402.5.1.4 in addition to Section C402.5.1.5.

Residential Structures

The 2021 IRC (Table R402.4.1.1) mandates sealing breaks for joints in the air barrier and a continuous air barrier in the building envelope. IRCs apply to detached one-and-two-family townhouses and dwellings not exceeding three stories above grade plane height. They must also provide a separate means of egress with accessory structures not exceeding three stories above grade in height.

2024 IECC Proposed Changes

Development of the 2024 national model energy codes by the ICC is well on its way. In previous years, the final decisions rested on the votes of government officials. For 2024, two consensus committees (commercial and residential) that represent various stakeholders, will make the decisions. 

The 2024 IECC proposed changes aim to improve overall energy performance compared to the 2021 IECC, with 250 + proposed changes to the commercial energy code and 200 proposed changes to the residential energy code.

The Importance of Certification and Compliance

The current energy codes take cost-effectiveness into account in the latest building science and technology. States and municipalities that routinely adopt the updated codes, along with contractors and architects complying with the codes, can achieve the cost, climate, health, and safety benefits of the IECC International Codes (I-Codes). 

 The I-Codes address air barriers, insulation, HVAC equipment, windows, and other components that enhance occupant health and comfort, lower emissions, and ensure durability. The U.S. Department of Energy predicts that between 2010 and 2040, building energy codes will save the U.S. $138 billion, reduce CO2 emissions by 900 MMT, and lower energy use by 13.5 quads.

Comparing Construction Sealants

High-performing construction sealants offer durability, flexibility, ease of application, and sustainability. The building industry utilizes sealants with several different base chemistries including silicone, polyurethane, and polyether. 

 All types of sealant materials have positive attributes, but they also have limitations that result from the inherent chemical makeup of the products.

Silicone sealants may require solvent-based primers for certain substrates. The primers are often high VOC products which may require specific handling and application safeguards.  The primers are typically not environmentally friendly and can be a concern during use, storage, disposal, or in the case of accidental spillage.  Silicones cannot be coated with water-based products, which affects the cost of recoating a building with common architectural coatings. Silicones have a relatively sticky or tacky surface which tends to collect atmospheric dirt during its service life and can negatively impact the appearance of a building.

Polyurethane sealants have less UV durability than silicone or polyether sealants.  They are susceptible to embrittlement, cracking, and fading when exposed to sunlight. Polyurethane sealants also may require a primer with the same negative aspects as primers used for silicone sealants. 

Both silicone and polyurethane sealants break down into harmful chemicals if heated above their maximum operating temperatures and cannot be recycled.

Polyether-based sealants, like StoSeal STPESealant, are fast curing and sustainable. They combine the strength of polyurethane and the weather resistance of silicone to create a long-lasting sealant with excellent strength, adhesion, and flexibility. 

Polyether-based sealants maintain their color and appearance by natural UV resistance and by having a cured surface with high dirt-pickup resistance.

StoSeal STPESealant bonds to most building materials (masonry, concrete, wood, stone, fiber cement, vinyl, stucco) and can seal gaps and joints around floor lines, wall penetrations, fixtures, etc., for a tight building envelope.

Comparing Silicone, Polyurethane, and Polyether Sealants 

Silicone, polyurethane, and polyether-based sealants offer contractors readily available, easy-to-apply sealants. However, the right sealant depends on the environmental conditions and the project’s strength, aesthetics, and sustainability needs.

Silicone-Based Sealants

Silicone sealants’ soft and flexible nature conforms well to joints and provides high tensile strength. Silicone sealants also resist moisture, weather, UV rays, and high temperatures. However, they cannot be painted.

Pros of Silicone Sealants

• Abrasion and vibration resistance
• Good tensile strength
• Weather, temperature, and UV resistance
• Moisture resistance
• Broad applicability and can bond between most building materials
• Long-lasting
• No bubbles during curing
• Noncombustible silicone makes it applicable for fire-rated assemblies 
• USDA-compliant silicone sealants allow its use inside food-processing facilities
• Pumpable silicone sealant offers easy application and cleanup 

Cons of Silicone Sealant

• May require solvent primers for certain substrates
• Unpaintable
• Relatively high-cost

Polyurethane-Based Sealants

Flexible and paintable polyurethane sealant provides high cohesive strength that creates strong bonds and adherence to substrates and conforms well to joints. However, polyurethane sealants lack sufficient weather resistance and may break down when exposed to high temperatures and UV rays. 

Polyurethane sealants are pumpable, and gun-grade. Polyurethane sealants are available in a wide range of hardnesses from Shore 35 A to Shore 70 D.

Two types of polyurethane sealants are available: one-component and two-component.

• One-component polyurethane sealant cures by exposure to moisture in the atmosphere. One-component polyurethane cures relatively slowly. These products are ready-to-use with conventional tools which is convenient for construction.
• Two-component polyurethane sealants offer faster curing and good performance. However, two-component products must be mixed in the field during use which requires special equipment, experience, and attention to detail.  Field mixing also increases the opportunity for quality control problems and inconsistency of performance within the overall project.

Pros of Polyurethane Sealant

• Excellent cohesive and tensile strength and abrasion resistance
• High stability, wide adjustable range of performance
• Good adhesion, good strength, and tear resistance
• Good elasticity, excellent recovery, suitable for dynamic joints
• Excellent oil resistance
• Moderately priced
• Good flexibility under low-temperature conditions 
• Will not freeze and crack in a cold environment
• Wide bonding range

Cons of Polyurethane Sealant

• UV exposure will cause the polyurethane sealant to crack and bubble.
• In elevated temperatures (above 80°C (176°F)), polyurethane will chemically break down, which diminishes its mechanical properties, like hardness and abrasion resistance.
• Polyurethane sealant may require priming. 
• Polyurethane sealants lack sufficient water resistance, especially in alkaline water environments.
• Bubbles may form during curing that can compromise the adhesive bond.
• Two-component products have increased opportunities for problems caused by inconsistent or improper field mixing.

Polyether-based Sealants and Silyl Terminated Polyether (STPE)

Polyether-based sealants provide superior weather resistance, adhesion properties, and cure times by combining many of the benefits of silicone and polyurethane sealants. In addition, sustainable polyether sealants provide flexibility, durability, and tear—as well as temperature—resistance.

Silyl Terminated Polyether (STPE) incorporates silicon to provide advantageous characteristics of silicones attached to a flexible polyether backbone which provides beneficial properties similar to urethane sealants.

Silyl Terminated Polyether (STPE) sealant technology creates sealants with several superior high-performance features compared to polyurethane and silicone sealants:

• Durable and Weather Resistant: STPE sealants perform well in most weather conditions and at low temperatures (unlike polyurethane sealants) with no adhesion failures, cracking, splitting, or discoloration.
• Adhesion: STPE sealants provide superior cohesive strength, by adhering more effectively to many substrates, like concrete, metals, wood, plastics, and ceramics, compared to silicone and polyurethane sealants.
• Simple Application: STPE sealants bond well to most construction materials and may not require priming and can create a continuous smooth surface. In addition, STPE sealants can be painted after 24 hours. 
• UV Resistant: STPE sealants will not crack or yellow after extended periods of UV-light exposure, unlike polyurethane sealants.
• Cold Resistant: STPE sealants retain their properties to -50°F (-45°C).
• Flexibility: STPE sealants’ elongation characteristics can endure structural movement and withstand substrate vibrations or oscillations more effectively than silicone sealants. 
• Environmentally-Friendly: STPE products contain extremely low or no VOCs, unlike other sealants prone to off-gassing, like silicone and polyurethane, which will break down into harmful chemicals if heated past their maximum operating temperatures. STPE products are also recyclable. 
• Non-Reactive: STPE sealants will not corrode or oxidize metals.
• Storage Stability: STPE sealants have an excellent shelf life when not exposed to moisture.
• Cure Rate: STPE sealants have a faster cure and tack-free time over other sealant types

Choosing the Best Sealant – StoSeal STPE Sealant

Selecting a high-performing and long-lasting sealant and applying it according to the manufacturer’s instructions is vital to creating a tight building envelope. 

Sustainable polyether sealants, like StoSeal STPE Sealant, are a better sealant solution for most applications when compared to polyurethane and silicone sealants. It combines polyurethane’s strength and silicone’s weather resistance to produce a long-lasting sealant with excellent strength, UV resistance, adhesion, and flexibility. StoSeal STPE also offers excellent color stability and dirt pickup resistance which helps maintain an aesthetically pleasing building exterior.

Indoor pools, whether at in-ground level, partially in-ground, or a movable above-ground floor, contain a large body of water that creates higher humidity, warm temperatures, and elevated chemical levels within the room’s space. If not controlled, the moisture, heat, and chemicals will damage the room’s structural integrity. It can also create an uncomfortable and unhealthy environment. 

Therefore, the design of an interior pool room, including its soffits, ceilings, and walls, should include moisture, temperature, and chemical-resistant materials in order to help prevent structurally damaging corrosion, mold, and mildew and to protect the pool room’s integrity and air quality. In addition, the indoor pool room should have a dehumidification system to manage the humidity.

Other challenges to interior pool room installation include:

• Space limitation during installation
• Ensuring adequate structural support
• Achieving unique customization: shape, aesthetics, etc. 

Architects and builders can refer to the following standards and guidelines for help to design a long-lasting and healthy indoor pool: 

• Model Aquatic Health Code Section 4.2.2 
• ASHRAE Standard 90.1, Building Envelope Design
• ASHRAE Standard 62.1, Standards for Ventilation and Air Quality
• Aquatic Facility Operator Manual, Chapter 20, “Concepts of Automation and Control,” by the National Recreation and Park Association

Drainable EIFS includes an air and water-resistive barrier and a drainage plane that allows incidental moisture to exit the wall assembly. The drainage cavity is achieved by applying vertical ribbons of adhesive that adheres the insulation to the air and water-resistive barrier, providing an effective exit path for any incidental moisture that penetrates the wall assembly (ASTM E2273).

Not only can EIFS achieve most of the desired aesthetic styles, including brick, wood, stone, granite, stucco, metal and concrete. EIFS also allows for multiple finish options with the compatibility challenges associated with combining different building materials on a facade. Creating and accommodating different sizes, shapes, angles and configurations is another facet of the design flexibility that EIFS offers.

In addition to the cost of the EIFS itself, the lightweight nature of EIFS compared to heavyweight cladding like brick, precast, etc. can also reduce structural requirements, providing additional cost savings for the project.

EIFS systems offer a variety of insulation options – including GPS (graphite-enhanced, expanded polystyrene), mineral wool, EPS (expanded polystyrene), and XPS (extruded polystyrene) to create a high-performing, energy-efficient cladding.

Design of EIFS with Drainage

Unlike original EIFS, modern EIFS with drainage is not a barrier system. EIFS with drainage includes a sustainable cladding assembly with an air and water-resistive barrier, drainage-utilizing adhesive applied in vertical ribbons to create channels that allow for water drainage – and continuous insulation that lessens thermal loads on the building’s exterior wall and contributes towards current energy code goals and compliance. Durable EIFS also complies with NFPA 285 (referenced in 2021 IBC Section 1403.5) to limit vertical and horizontal fire spread.

EIFS Creates Magnificent Curves and Colors 

The Center of Hope Hill Country Community Clinic of Redding, CA, chose a StoTherm ci EIFS system due to its lightweight nature and the ability to design straight and curved walls. In addition, the architect utilized Sto’s tools to integrate their color palettes into his design software, which allowed him to create an accurate color representation of the finished structure.

The clinic and architect were also impressed with Sto’s easy installation and sustainability features, including:

• Durability: Long-lasting exterior enclosure resists damage from hot and cold temperatures, moisture, wind, and other external forces.
• Energy-Efficiency: The continuous insulation of the EIFS system creates an energy-efficient building enclosure in a climate that experiences very warm summers and cool, wet winters.

Create Multiple Aesthetics with EIFS

Sto Products: StoTherm®ci, StoCast Wood, Sto® Essence Finish
Architect: Klingner & Associates, P.C.
Applicator: Burgener Plastering, Inc.
Contractor: Hein Construction Co.

For crafting the new River Bend Food Bank, priority number one was taking the previously uninsulated block building and turning it into a high-performing, sustainable structure. The north and east facades featured brick walls with masonry backup, while the south and west walls were all cement masonry units (CMU). According to architect Melissa Goodwin with Klingner & Associates, the CMU walls were in “pretty bad shape.” The original walls were repaired and repointed to create a suitable substrate for the application of the continuous insulation component of the EIFS system on a previously uninsulated block building. 

The StoTherm ci is finished with 12,000 square feet of Sto’s Essence, an acrylic finish with dirt pick-up resistance in a Medium Sand texture in two colors, Jersey Cream and Superior Bronze. “That is one of the best things about EIFS for remodeling, you can do so much from a visual perspective with these types of systems,” said Chuck Burgener (Burgener Plastering, Inc.). However, the architects designed the building for a different type of cladding for the two main entrances on its northeast corner. Originally searching for a cement board product, architects instead settled on StoCast Wood, which enabled them to deliver this time-honored and desirable aesthetic and something that was available from the same manufacturer.

Sto’s exterior wall systems are equipped with the same control layers behind the cladding materials, all of which are designed to keep buildings dry and thermally efficient. Therefore, with Sto, architects can design high-performing structures with contemporary visual appeal even when numerous cladding materials are required, which is now becoming a mandate in cities across the country. For River Bend Food Bank and FISH of Galesburg, architects were able to specify multiple claddings from a single supplier. This eased the specification process and reduced the number of trades needed on site to install materials, saving both time and money

Stunning Curves 

The Greenhouse Dispensary 

Sto Products: StoTherm® ci and Stolit® Milano
General Contractor: Pacific Construction
Applicator: G & J Services, Inc.
Architect: Camburas & Theodore, Ltd.

To renovate this nearly 70-year-old Greenhouse dispensary, the building team used the StoTherm® ci EIFS system to create stunning, flowing curves, then applied a Stolit® Milano finish to make the building shine. 3D modeling and precision laser cutting of the complicated forms allowed the structure to come together in pieces to produce a unique design. 

StoTherm ci is noted for its enhanced energy efficiency and protection against moisture intrusion. To be sure, it serves those purposes in this project, but that is not what is noteworthy here. What’s groundbreaking was the way the Sto EPS insulation board component of the system was used to create the design’s organic shapes. Traditionally, those shapes would have been rendered by skilled artisans, working tediously with their hands, literally shaving away material until the desired forms emerged. Instead it was done with incredible efficiency and accuracy in the applicator, G & J Services’ facility. Drawings from Camburas Theodore were converted into 3D computer models, and then, using CNC laser cutting technology, G & J shaped the foam, outputting it in two-foot sections which were dutifully numbered and delivered to the jobsite. Once there, it was a simple matter for the applicator to assemble them following the original design. A smooth texture adds to the free-flowing feel of the facade. It was achieved with a Stolit Milano finish in bright white that makes the flowing organic forms pop even more, especially when illuminated at night by white LED lights. The overall effect of the building is soothing and striking.

High-Rise Construction with EIFS

New York’s Hyatt House 32-story hotel construction project presented several challenges, including the building’s irregular concrete substrate and design, which made it necessary to work on one floor at a time. Fortunately, StoTherm® ci Lotusan® with the StoSignature® Stone (and the help of the Sto engineer and distributor) provided a solution to the building’s irregular surface conditions. The expanded polystyrene utilized in the StoTherm ci Lotusan system allowed the construction team to make custom adjustments in the insulation thickness to account for the uneven concrete substrate.

Georgia King Village

L+M Development chose StoTherm® ci Essence to upgrade the nearly 50-year-old, 18-story Georgia King Village affordable housing’s building envelope. The complex was in distress needing various improvements to both individual units and the structural integrity. Rehab priorities included installing a new facade/envelope/exterior to replace the uninsulated precast concrete facade. Heat and cold were leaking through the walls, and a livable temperature could not be properly maintained. As a result, the Georgia King Village residents were suffering. Utilizing a StoTherm ci system helped to create a more efficient, comfortable, and attractive structure with improved structural integrity.

Silyl Terminated Polyether (STPE) sealants are fast-cure sealants that combine the weather resistance of silicone with the strength of polyurethane to create a long-lasting sealant with superior strength, adhesion, and flexibility. Fast-cure sealants also maintain their appearance by limiting adherence of dust and debris, which can be a problem with other types of sealants.

STPE sealant bonds to most construction materials (stone, masonry, concrete, fiber cement, vinyl, stucco, wood) for sealing joints and gaps around wall penetrations, floor lines, fixtures, etc., for a tight building envelope. 

A tight building envelope keeps outside elements (primarily moisture and air) from infiltrating a structure. Correctly applying a high-performing STPE joint sealant, like StoSeal STPE Sealant, is critical to weatherproofing a building’s exterior and protecting its integrity and health.

STPE Sealant Advantages

STPE technology creates sealants with several high-performance features compared to polyurethane and silicone sealants:

• Cure Rate: STPE sealants cure quickly, even at low temperatures.

• Weather Resistant and Durable: STPE sealants perform well at low temperatures and in most weather conditions, from dry to extremely wet and rainy, with no splitting, cracking, discoloration, or adhesion failures.

• Cold Resistant: STPE sealants retain their properties to -50°F (-45°C).

• UV Resistant: STPE sealants will not crack or yellow after extended periods of UV-light exposure, unlike polyurethane sealants. 

• Easy Application: STPE sealants do not require priming (unlike silicone and polyurethane) and can create a continuous smooth surface that can be painted after 24 hours. 

• Flexibility: STPE sealants’ elongation characteristics can endure structural movement and withstand substrate vibrations or oscillations more effectively than silicone sealants. 

• Adhesion: STPE sealants adhere more effectively to various substrates, like concrete, wood, plastics, ceramics, and metals, compared to polyurethane and silicone sealants.

• Environmentally Friendly: STPE products contain extremely low or no VOCs, unlike polyurethane that is prone to off-gassing.

• Non-Reactive: STPE sealants will not corrode or oxidize metals.

• Storage Stability: STPE sealants have an excellent shelf life when properly stored in dry conditions.

Which fabricated glass product, toughened glass or tempered glass, offers the most benefits over annealed (regular) glass? The answer is neither – tempered glass and toughened glass are different in name alone, and they provide homes, businesses, and institutions with the following benefits and features:

Strength

The manufacturing of tempered and toughened glass involves processing glass under controlled thermal or chemical treatments to increase its strength. Heat treatment can make the glass six times stronger and more impact, wind, and weather resistant than untreated glass – for a safer consumer product. In addition, the code of federal regulations (Consumer Product Safety Commission) cites ANSI Z97.1, which crosslinks to ASTM C1048, mandating that fully tempered glass (Kind FT) achieve a surface compression of 10,000 lbs. in2 (psi) or more, which protects it from breakage up to 24,000 psi. In contrast, annealed glass will break at only 6,000 psi.

Safety

Increasing the compressive stresses on the glass’s surface creates tension in the interior. If the glass breaks, the mechanical stresses cause the glass to crumble into small, smoothed-edged granules that are much less dangerous than regular glass that splinters into jagged shards of plate glass.

U.V. Protection

Tempered (toughened) glass blocks nearly all of the sun’s UVB rays; however only a portion of UVA rays. 

Thermal Resistant

Toughened glass can withstand high temperatures or significant temperature differences (thermal shock) without damage compared to regular glass. 

Design Versatility

Designers can use versatile tempered glass for many applications, including:

• Balusters, escalators, handrails, staircases, etc.
• Partition for airports, offices, resorts, homes, etc.
• Sliding doors and windows
• Decorative panels in interior design
• A building’s facade

Will Tempered Glass Break?

Thermal stress can cause tempered (toughened) glass to break during installation. In addition, a chipped edge can develop into a more extensive break.

How to Make Toughened (Tempered) Glass?

Manufacturers transform annealed (conventional) glass into toughened (tempered) glass by heat or chemical treatments.

Heat Treatment

• Before tempering, fabricators cut the annealed glass to the desired size.

NOTE:  Etching or edging tempered glass will reduce its strength, which can potentially lead to product failure. 

• Fabricators examine the glass for imperfections that could lead to breakage during tempering. 
• Next, the glass moves through a tempering oven that heats the regular glass to a uniform temperature of 600 to 700°C (1112 to 1292 °F) – the industry standard is 620 °C (1148 °F).
• After heating, the glass is placed in an annealing lehr (long kiln), where it undergoes a high-pressure cooling procedure (quenching) in which high-pressure air blasts the glass from an array of nozzles in various positions, cooling it to 60 °C (140 °F). Quenching cools the glass’s outer surface faster than its center.
• As the center cools, it pulls away from the outer surface, which creates tension in the center, compresses the outer surface, and strengthens the tempered glass.

Chemical Treatment

Fabricators use various chemical exchange ions on the surface of the glass to create compression. However, this method produces less strength than the heat treatment.  It is also more costly than heat treatments.

Identifying Toughened or Tempered Glass

A stamp in the corner of the sheet of glass identifies the glass as tempered (toughened). The identifier will show the manufacturer’s name and the CPSC (Consumer Product Safety Commission) standards.

To classify as tempered glass, it must achieve a minimum compressive stress on its surface of 69 MPa (10,000 psi). To be considered a safety glass, its compressive stress on its surface must exceed 100 Mpa (15,000 psi), which makes it safe for high-pressure and explosion-proof applications. 

StoVentec® Glass Rainscreen® Systems

The StoVentec® Glass Rainscreen® System is a straightforward-to-install toughened (tempered) glass rainscreen opaque architecture system that helps ensure a successful, long-lasting wall assembly of thermally-efficient insulation that limits damaging condensation and lowers the cost of heating and air-conditioning. At the same time, the tempered glass structural frame improves safety against high impact, wind, and fire.

StoVentec® Glass Rainscreen® System Components

The StoVentec® Glass Rainscreen® System consists of toughened (tempered) glass-faced composite panels (outer layer) to keep the weather out. Mounting brackets between the panels produce a gap that permits air circulation (ventilation), moisture evaporation, and drainage. Thermal insulation is added within the rainscreen cavity, and a Water Resistive Barrier (WRB) is applied on the exterior wall surface.

Decorative Glass Panel

The durable and decorative toughened glass panel can withstand the weather, and it has four to five times more strength than regular glass. If broken, the toughened glass will break into smaller, safer pieces and stay bonded to the backing board.

Support Structure

The aluminum rails and galvanized or stainless steel brackets carry the panel system and resist wind loads. Aluminum provides a greater strength-to-weight ratio (at less cost), while stainless steel enhances thermal performance. The thermal conductivity of stainless steel is 17 W/m K versus aluminum’s 210 W/m K. Combining aluminum rails and galvanized or stainless steel brackets maximizes performance and cost. The number of brackets depends on the wind loads, the system’s depth, and the substrate’s properties. 

Insulation

Insulation (typically made of mineral fibers) insulates the substrate and surrounds the brackets. The insulation minimizes condensation (to eliminate structurally damaging and unhealthy mold), lessens temperature fluctuations, and helps to keep the wall warm.

Continuous Air and Water-Resistive Barrier

A continuous air and water-resistive barrier stops moisture from infiltrating the structural wall. The 2021 IBC mandates a weather-resistant exterior wall envelope for all structures, with a few exceptions like concrete and masonry walls.

However, leaks can occur due to improper installation or deterioration that permits water to flow through tiny openings by gravity, surface tension, capillarity, air pressure differences, and momentum (kinetic energy). A rainscreen cladding system will limit water intrusion by providing a drainage plane.

Improved Safety 

Blast-Tested

The strength and integrity of the StoVentec® Glass Rainscreen® System can pass rigorous blast tests, which makes it suitable for public spaces like airports and railway stations.

Wind Resistance

Properly installed galvanized or stainless-steel wall brackets and aluminum horizontal and vertical rails create the sub-construction that form a solid structural link between the supporting wall construction and the facade. This structural design absorbs dead loads and wind and transfers them to the supportive wall construction.

Fire Breaks

Rainscreen installation must comply with fire-resistance testing mandates, like the ASTM E119 and NFPA 285 standards.

Why Choose StoVentec® Glass Rainscreen® Systems?

Robust StoVentec® Glass Rainscreen® Systems contribute significantly towards energy-efficient, safe, low maintenance, and comfortable buildings with healthy I.E.Q. 

The StoVentec® Glass Rainscreen® consists of toughened (tempered) glass-faced composite panels (outer layer) that can enhance a building’s safety, strength, U.V. protection, thermal resistance, and design versatility.

Unfortunately, the building industry struggles to take advantage of these construction opportunities due to labor shortages and supply chain problems, which can slow, if not stop, construction schedules.

For building companies to benefit from the current hospitality construction market, they must redirect their building practices towards cost-effective building materials and less labor-intensive construction methods, like prefabricated construction.

What is Prefab Construction?

Experienced fabricators manufacture customized, project-specific finished exterior wall panels to specifications that meet requirements for fully-engineered, tested and code compliant systems. The prefab walls include exterior cladding (like stone, wood, stucco, or other material), fenestration, air/water/vapor barrier control systems, insulation, flashing, and structural framing. After transporting the prefabricated wall systems to the job site, a relatively small number of workers can lift and install the prefabricated panels following the architect’s plans.

Sto Panel Technology® Prefabricated Wall Panels

Sto Panel Technology® prefabricated wall panels provide architects and contractors with a superior sustainable solution to many of the challenges of hospitality construction, including labor shortages and supply chain problems, to help ensure that the projects stay within budget and on time, and meet code and safety requirements. Prefabricated construction offers building owners long-lasting and energy-efficient complete building envelope systems with a wide variety of aesthetic facade choices

Why Use Prefab Construction in Hospitality?

Prefab construction for new and renovation projects adds many short and long-term benefits to the hospitality industry to help ensure the financial success of their businesses.

Hastens the Construction Timeline

Prefabrication quickens the completion of the hotel’s exterior, to save money and allow for quicker access to the hotel’s interior. Prefab hospitality construction will enable owners to begin collecting revenues sooner.

Prefabrication quickens construction timelines because:

• Installation takes days or weeks, not months, like conventional construction
• Manufacturing in a controlled manufacturing environment eliminates weather or other field conditions that can delay construction schedules
• Allows workers to complete a vertical expansion of a hotel quickly
• Manufacturing panels in quality-controlled factories allows for building envelope inspection, testing, and checking before installing at the project site

Helps Hospitality Projects Stay on Budget

Choosing prefab construction will help hotel owners save money, which allows them to redirect those savings elsewhere on the project:

• Lightweight panels reduce job site labor, require less specialized trades, limit the use of scaffolding, and lessen structural needs
• Minimizes debris and construction waste and debris, which saves money
• A single-source warranty to give owners added protection

Improves Quality Control

Manufacturing of prefabricated wall panels occurs in a climate-controlled indoor environment by an experienced crew and precise machine equipment. The process ensures uniform quality between the sub-assemblies of the structure and conformity to the building code.

Sustainable, Prefabricated Wall Panels

A sustainable hotel aims to minimize water and energy use, limit carbon emissions, and create long-lasting hospitality buildings – all features that save time and money on repairing or rebuilding. Builders can also quickly retrofit an existing hotel with prefabricated wall panels, an aesthetic, energy-saving, economical, and sustainable alternative to new construction. Sustainable benefits of prefab construction include:

• Manufacturing prefab walls inside a facility can cut job site waste compared to traditional construction. It also allows for the in-house recycling of materials.
• The controlled environment of a prefabricated factory ensures more precise construction, tighter joints, and adequate storage of materials, to enhance the final product’s overall quality and energy efficiency.
• Factory-built construction significantly reduces truck traffic, material suppliers, and equipment around the job site, which minimizes soil disturbance and erosion of the area.

Aesthetic Flexibility of Prefabricated Wall Panels

A well-designed, aesthetically pleasing hotel helps attract visitors and enhance their experience so they will return and recommend your hotel to other travelers.
Prefabrication offers architects several significant aesthetic benefits:

• Design flexibility allows architects to match or complement the aesthetics of the original building.
• Provides a way to quickly rebrand a hotel without completely rebuilding.
• Aesthetic flexibility, from a modern, sleek design to classic metal, brick, and stone.

A tight building envelope keeps outside elements (primarily air and moisture) from infiltrating a structure. Correctly applying a high-performing STPE joint sealant, like StoSeal STPESealant, provides a critical step towards weatherproofing a building’s exterior and protecting its integrity and health.

Why Buildings Need High-Performing Sealants

Achieving a tight building envelope requires strategic air sealing of major gaps. ASHRAE research identified five critical locations that require air sealing based on ACH50 reduction. ACH50 stands for air changes per hour at 50 pascals pressure differential. It represents the number of times the air volume in a building changes per hour at 50Pa of pressure – a significant measure of a building’s energy efficiency.

1. The top plate to attic drywall achieves a potential ACH50 reduction: up to 1.6 exchanges – the greatest impact of all locations.
2. Recessed can lights to the finished surface achieve a potential ACH50 reduction: 0.2+ exchanges.
3. Duct boot to finished surface achieves a potential ACH50 reduction: 0.2+ exchanges.
4. Band joist (top and bottom) achieves a potential ACH50 reduction: 0.4 exchanges.
5. Between the house and garage’s wall achieves a potential ACH50 reduction: 0.2+ exchanges.

The Benefits of STPE Sealants

STPE technology creates sealants that have several high-performance features compared to silicone and polyurethane sealants:

Flexibility: STPE sealants’ elongation characteristics can endure structural movement and withstand substrate vibrations or oscillations more effectively than silicone sealants.
Adhesion: STPE sealants adhere more effectively to various substrates, like concrete, wood, plastics, ceramics, and metals, compared to polyurethane and silicone sealants.

UV Resistant: STPE sealants will not crack or yellow after extended periods of UV-light exposure, unlike polyurethane sealants.

Environmentally Friendly: STPE products contain extremely low or no VOCs, unlike other sealants prone to off-gassing.

Weather Resistant and Durable: STPE sealants perform well at low temperatures and in most weather conditions, from dry to extremely wet and rainy, with no splitting, cracking, discoloration, or adhesion failures.

Easy Application: STPE sealants do not require priming (unlike silicone and polyurethane ) and can create a continuous smooth surface that you can paint after 24 hours.

Cure Rate: STPE sealants cure quickly, even at low temperatures.

Cold Resistant: STPE sealants retain their properties to -50°F (-45°C).

Non-Reactive: STPE sealants will not corrode or oxidize metals.

Storage Stability: When not exposed to moisture, STPE sealants have an excellent shelf life.

StoSeal STPE Versatile, High-Performance Adhesive Sealant

Sto Corp. recently launched StoSeal STPE Sealant – a high-quality, low-odor, isocyanate-free, one-part hybrid sealant with a VOC content of 8 grams per liter. Durable, low-modulus, non-sag, and flexible StoSeal STPE Sealant provides superior moisture and weathering resistance.

StoSeal STPE Sealant’s excellent adhesive properties work effectively with StoTherm® ci, StoPowerwall®, StoQuik®, and StoVentec® exterior wall systems and with StoGuard® air- and water-resistive barrier system for vertical above-grade new opaque wall and building restoration applications. You can use it for panel-to-panel joints in prefabricated construction, interior use, metallic and cementitious substrates, storefront systems, air sealing applications, and concrete repair.

Benefits and features of StoSeal STPE Sealant include:

• High-Movement: Offers +100%/-50% movement – suitable for low and high movement joints
• Simplifies installation
  • Primer-free bonding to most substrates
  • Easy to gun and tool

• Durable, Long-Lasting: StoSeal STPE Sealant offers superior moisture-, UV-, weathering-, aging-, and shrink-resistance
• Environmental-Friendly: StoSeal STPE Sealant lacks Isocyanate-free and contains very low VOC – it will not bubble and releases very little odor
• Storage Stable: When properly stored, the sealant will last 12 months in original, unopened packaging

StoSeal STPE Sealant Compliance Testing

StoSeal STPE Sealant conforms to, or tests according to the:

• ASTM C920: Type S, Grade NS, Use NT, A, M, Class 100/50
• Federal Spec. TT-S-00230C Type II
• AAMA 808.3 (Type1) Exterior Perimeter Sealing
• ASTM C1382 for use with EIFS

Where to Use StoSeal STPE Sealant

StoSeal STPE Sealant bonds to most common construction materials, including masonry, concrete, stone, stucco, fiber cement, aluminum, steel, wood, and vinyl. You can use it for various applications in Sto proprietary wall systems and other wall assemblies. Examples of applications include:

Thermal expansion and contraction joints

• Control joints
• Panel-to-Panel joints between precast, metal frame, and other prefabricated wall construction
• Deflection joint sealant at floor lines
• Air seal at interior or exterior joints and seams for air barrier continuity
• Perimeter weather seal around windows, doors, scuppers, and other through-wall penetrations
• Perimeter weather seal around fixture attachments
• Bedding sealant for flashing, flanged windows, and related applications

Why Choose StoSeal STPE Sealant?

Air sealing the joints, penetrations, and other gaps in a building envelope with high-performing StoSeal STPE Sealant can significantly contribute towards a tight building envelope. A tight building envelope protects a building’s integrity and increases the occupant’s comfort level by preventing moisture, drafts, and unwanted noise from infiltrating the building. In addition, the sealant can also improve indoor air quality by minimizing mold and pollution exposure, and can lessen energy use and save money.

Durable, weather-resistant, flexible, and non-toxic StoSeal STPE Sealant offers superior adhesion when applied to vertical above-grade new opaque walls and building restorations.

Modern Issues with Traditional Building Projects

Weather Delays

In 2021, weather and climate disasters in the U.S. cost over $1 billion, which significantly impacted the construction industry. Yearly, weather delays impact 45 percent of construction projects worldwide, costing billions of dollars. The increasing intensity and frequency of weather events due to climate change continues to threaten to accelerate construction delays.

Labor Shortages

The continuing lack of skilled and unskilled construction workers makes it challenging for building professionals to stay on schedule and budget. According to Associated General Contractors of America’s 2023 Construction Outlook National Survey, 80 percent of building professionals report difficulty filling hourly and salaried positions, with 58 percent predicting this will worsen over the next 12 months. In addition, 72 percent of building professionals indicated an increase in base pay rates between 2021 and 2022 to attract workers.

Supply Chain Issues

Since 2020, the COVID-19 pandemic, transport bottlenecks, and geopolitical uncertainties have created supply chain issues that have impacted the availability of construction materials and created long lead times and volatile prices, which has made it challenging to estimate project costs accurately and stay on schedule.

In 2023, building professionals report the following most significant concerns:

• Material costs (73 percent)
• Project delays due to supply chain issues (63 percent)

Prefab Wall Construction

To combat the challenges of weather, labor shortages, and supply chain issues, builders are increasingly turning to sustainable prefab panelization, like Sto’s prefabrication solution, Sto Panel® Technology, which helps them stay on schedule and budget.

Insulated Metal Wall Panels

Manufacturers make insulated metal panels (MIPs) from copper, aluminum, steel, or zinc. IMPs provide several benefits, including durability, fire resistance (according to NFPA 285 and ASTM E119), and design versatility. However, IMPs are costly, especially those made of copper and zinc. In addition, steel and aluminum IMPs may degrade over time due to corrosion.

Exterior Insulation and Finish Systems

EIFS wraps a building with continuous insulation (R-value between 4 and 5.6 per inch), which lessens thermal bridging, improves air and moisture infiltration, and lowers energy consumption. In addition, EIFS complies with NFPA 285 (referenced in 2021 IBC Section 1403.5) and all other major fire-resistant tests that are required by building codes to limit fire spread horizontally and vertically.

Components of EIFS

EIFS cladding includes several layers over the exterior sheathing that creates superior insulation and moisture protection compared to IMPs. The components (layers) of EIFS typically include:

A water-resistive barrier over the substrate that prevents moisture from infiltrating the wall system
Dual purpose ribbons of adhesive that also provide drainage capability for any moisture
An insulation layer of expanded polystyrene (EPS), mineral wool, graphite polystyrene (GPS) or extruded polystyrene (XPS)
A layer of fiberglass mesh embedded in the base coat that protects against cracks due to thermal expansion, freeze/thaw cycles, and shifting foundations and adds additional durability
A base coat in the glass-fiber reinforcing mesh that is applied on top of the insulation
A finishing coat that gives the exterior surface color, texture, and protection

Structural and Aesthetic Advantages of EIFS

EIFS insulation cladding’s structural and aesthetic appeal makes it a superior choice for new and retrofitted construction. In addition, builders can apply these multilayered cladding systems to wood, concrete, or steel substrates in any climate.

Specific design and structural benefits include:

• Energy-efficient EIFS with drainage and CI meet the mandates of ASHRAE 90.1.
• EIFS resists flames spreading within the combustible component/core of panels from one story to the next. EIFS also limits the lateral spreading of flames from the compartment fire origin to adjacent spaces (NFPA 285).
• Fire-resistant, passes building code requirements for ignitability (NFPA 268) and fire resistance (ASTM E119).
• Low-maintenance EIFS resists structurally unhealthy and damaging mold.
• Aesthetically versatile, EIFS can mimic brick, wood, granite, stone or concrete. There are also EIFS systems for use with thin brick, natural stone, ceramic tile, or cultured stone.

Energy-Efficiency

All EIFS have ci, which lowers energy use, saves money, and satisfies today’s energy codes and customer demands.

Condensation Resistance

EIFS insulation thickness helps prevent the interior air from reaching the dew point (the temperature when water vapor turns to water) to limit, if not eliminate, condensation within the wall system.

Fully-adhered, StoGuard® fluid-applied air and water-resistive barrier’s seamless monolithic exterior wall air and moisture barrier protects against moisture intrusion and unwanted air movement – ideal for all types of construction.

Impact Resistance

The use of high-impact mesh for EIFS installations can add additional impact resistance. EIFS systems meeting the stringent Miami-Dade Notice of Acceptance (NOA) are also available for use in areas where there is risk for tropical storms and hurricanes.

Fire Resistance

Fire-resistant EIFS passes the mandated building code tests for ignitability (NFPA 268), fire resistance (ASTM E119), and intermediate multi-story fire test (NFPA 285). Click here or contact one of our qualified representatives at 1-800-221-2397 for more on NFPA 285 testing of Sto cladding systems.

Quality Sealants

Preventing water intrusion into the wall assembly must include the use of quality sealants, like StoSeal STPE Sealant (link to: https://www.stocorp.com/stoseal-stpe-sealant/) in the following areas:

• Perimeter weather seal around windows, doors, scuppers, and other through wall penetrations
• Perimeter weather seal around fixture attachments

In addition, hydrophobic acrylic coatings and finishes contribute towards ensuring all layers of the building envelope (including the finished surface layer) work to control moisture infiltration and accumulation, which is vital to meeting the demands of today’s building owners and code requirements for healthy, sustainable, and resilient structures.

How to Measure the Hydrophobicity of a Coating or Finish

Manufacturers measure hydrophobicity by setting a water droplet on the product’s surface and watching the angle as the droplet moves – the contact angle. Manufacturers define coatings with a contact angle of 90 degrees or greater as hydrophobic, while coatings with 150 degree or greater contact angles are super-hydrophobic.

Super-hydrophobicity allows more water to roll off the wall, which prompts faster drying and removal of dirt. In addition, super-hydrophobicity protects a building’s exterior and long-term value by resisting mold, water, dirt, staining, extreme temperatures, and UV rays.

The Lotus Effect – Super Hydrophobic

A 7000 magnified lotus leaf microstructure.

StoColor® Lotusan® Mimics the Lotus Leaf

Smooth, super-hydrophobic StoColor® Lotusan® is an above-grade, vertical exterior wall coating with Lotus-Effect® Technology. Builders can use it on stucco, masonry, EIFS, concrete and previously painted wall surfaces.

The Science Behind StoColor® Lotusan® 

Tiny wax pillars (smaller than 100 microns apart) coat the lotus plant’s leaves, which helps to waterproof and clean the plant. The high surface tension of water does not allow it to infiltrate through the pillars and into the leaf, which creates a hydrophobic effect that forces moisture to bead and roll off the leaf. The beads pick up dirt particles as they roll off the leaf, which keeps the lotus leaves clean and dry — the lotus effect.

TowerHouse Condominium in Miami Beach, Florida

The condo association chose StoColor® Lotusan® coating to paint this 50-year-old structure because of the coating’s longevity, waterproofing capacities, and self-cleaning Lotus-Effect® Technology.

Problems with Conventional Exterior Wall Coatings

Conventional exterior coatings lack resistance against many outdoor elements (bulk water, temperature, UV exposure, impact, pollution, and biological organisms), which affects the structure’s integrity and the occupant’s safety and comfort:

• Bulk Water: Rain, dew, snow, humidity, etc., can cause a conventional water-based coating to soften and become sticky, which further attracts dirt.
• Temperature and UV exposure: Hot temperatures and sun rays can degrade coatings on the building’s exterior, which leads to fading after years of exposure.
• Impact: Flying debris, hail, building movement, equipment, etc., can all cause abrasions and compromise exterior cladding paint and coatings.
• Pollution: Nitrogen oxides, smoke, dust, soot, fertilizers, nitrates, etc., can all damage a facade’s coatings.
• Biological Organisms: Fungi and mildew create an unattractive green appearance that can diminish the coating’s effectiveness. In humid climates, fungal growth tightly bonds and leaves a coating on the coating’s surface.

Hydrophobic Coatings and Finishes Repel Water

Hydrophobic coatings and finishes repel water, which helps resist mold, algae, and mildew and reduces maintenance costs by increasing the time between recoats.

Stolit® HDP® Hydrophobic Finish

Builders can use ready-mixed Stolit® HDP® as an exterior and interior decorative textured wall finished (fine, medium, swirl, and freeform textures) on Sto wall systems and over-prepared vertical above-grade masonry, concrete, and stucco substrates.

Stolit® HDP® provides several other significant benefits and features, including:

• Excellent water repellency, which helps maintain clean walls
• The high water vapor permeability allows a substrate to breathe naturally, which provides superior resistance to blistering and peeling.
  Integral Colorants create lasting, uniform color
• Enhanced Polymer Technology spreads and floats easily and provides UV resistance.
• Water-based, and is safe, non-toxic, and cleans up with water
• Low VOC improves a building’s IAQ and protects the environment

Super-Hydrophobic Coatings – The Ultimate Solution for Water Resistance and Moisture Damage Prevention

Super-hydrophobic microstructure coatings repel water by rolling it off the surface, in order to limit an exterior wall’s contact with dirt and water. This process mimics the lotus leaf’s water-repellent surface and self-cleaning abilities.

The Advantages of Super-Hydrophobic Coatings

Super-hydrophobic acrylic coatings for recoating existing buildings and new construction repel water and dry quickly. The process lessens the opportunity for mildew, mold, dirt, and other pollutants to grow or stick on the surface.

Super-hydrophobic coatings also help maintain the building’s exterior aesthetic and benefit the building owners by enhancing the wall’s integrity, lessening costs, and reducing maintenance:

Long-Term Integrity and Appearance Advantages

Hydrophobic coatings resist weather, algae, mold, mildew, and UV, which enhances the exterior wall’s long-term integrity and appearance.

Lessens Long-Term Costs

Hydrophobic coatings create durable exteriors, which can eliminate annual pressure washing and allow for longer periods between recoating, lessening the total cost of ownership. Over two decades, hydrophobic coatings may save nearly 80 percent of the total expense of a standard coating product.

Reduces Maintenance

Hydrophobic coating’s water-shedding properties ensure rapid drying and dirt removal and produce coatings that last up to ten years – conventional coatings only last two to three years. Therefore, hydrophobic coatings have lower long-term maintenance costs.

Hydrophobic acrylic coatings also often include silicone polymer technology, which provides longer fade resistance durability than conventional acrylic coatings.

Super-Hydrophobic StoColor® Lotusan® Coating

Highly water-repellent StoColor® Lotusan® surface coating with LotusEffect® Technology keeps buildings’ facades clean and attractive while also saving money on maintenance and recoating. In addition, easy and seamless to apply StoColor® Lotusan® comes in numerous colors within the StoColor® offerings.

StoColor® Lotusan® provides three significant features: super-hydrophobic, vapor permeability, and UV resistance:

1. Super-hydrophobicity provides:

• Enhanced resistance to mold, mildew, and algae
• Superior water repellency
• Excellent dirt resistance

2. Vapor permeability allows the substrate to breathe naturally to resist blisters caused by trapped water vapor.
3. UV resistance ensures a facade with superior color retention.

Self-Cleaning StoColor® Lotusan®

StoColor® Lotusan® is a superior coating solution for new construction and recoat projects over stucco, concrete, EIFS, fiber cement board, and pre-painted or primed wood substrates. The self-cleaning component of super-hydrophobic StoColor® Lotusan® effectively protects the exterior facade with the following features:

• Excellent weather and chalk resistance
• UV-stable
• High water vapor permeability
• Resists the growth of algae, mold, and mildew
• Smooth matte (flat) surface
• High level of water- and dirt-repellent after the coating dries

Protect Exterior Walls from Water Damage with StoColor Lotusan Super-Hydrophobic Coating and Stolit HDP Hydrophobic Textured Finish

Hydrophobic Stolit HDP textured finish and super-hydrophobic StoColor® Lotusan® coating will both repel water, which helps keep a wall attractive while also saving money on recoating and maintenance.

Super-hydrophobic StoColor® Lotusan® exterior coating (Lotus-Effect® Technology), however, allows dirt and rain to flow off the coating surface like rain droplets falling off a lotus leaf, which helps protect the facade from water damage and keeps it attractive while also saving money on recoating and maintenance.

Adequate moisture management will fortify the structure’s long-term integrity and ensure good indoor air quality.

Rainscreens Control Moisture Within a Wall System

According to the E.P.A., a building’s design must include three features to control moisture. Fortunately, a quality rainscreen system, like StoVentec® Rainscreen® Systems, provides all these features:

1. Controls bulk liquid water from snow, rain, etc.
2. Stops a buildup of indoor humidity and water vapor migration by diffusion and airflow to minimize condensation and moisture absorption into cool surfaces and materials
3. Made with moisture-resistant building materials

Are Rainscreen Systems Appropriate for My Climate?

Building codes may require a rainscreen, especially in regions that experience heavy rain. Designing structures according to current building codes and standards provides some assurance that the building will stand up to severe weather events. However, building code compliance alone does not guarantee protection since the codes are typically based on historical climate and weather data, which may not consider the increasing hazards of recent decades.

Therefore, regardless of the location and code mandates, installing a rainscreen, like StoVentec® Rainscreen® Systems, will provide superior moisture protection to building envelopes, particularly against catastrophic events.

StoVentec® Rainscreen for Render Facades

StoVentec Render proved to be the ideal solution for the facade renovation of the Omaha Henry Doorly Zoo & Aquarium Dome and Theater.

Climate Change Escalating Severe Weather Events

Global temperatures climbed to record levels over the last two decades, intensifying worldwide water-related disasters, including lengthy droughts and severe flooding, according to a study from NASA scientists.

For example, this year, atmospheric rivers in California brought severe-extensive rainfall and snow, which caused significant flooding, mudslides, unusable roads, and collapsed bridges. The same region also experienced extreme drought in the past several years. These combined events put thousands of homes and buildings at high risk of flooding.

To protect against increasingly severe weather events, the building community must provide adequate waterproofing components in all future new and remedial construction.

2021 Building Code Changes for Water-Resistive Barriers

Evolving building codes aim to create more resilient buildings. For instance,
the 2021 International Building Code updated water-resistive barrier requirements for cementitious barriers, like exterior plaster (stucco), that continually get wet and dry throughout its lifespan, and made water drainage vital. The need for a water-resistive barrier typically depends on the project’s climate zone or geographical location.

The 2021 International Building Code (Section 2510.6) updates to water resistive barriers (W.R.B.) section for stucco over wood-based sheathing includes:

For Climate Zones A (Moist) and C (Marine):

• Option 1: 3/16″ (4.8mm) drainage cavity over the W.R.B. when applying stucco on wood-based sheathings like O.S.B. and plywood.
• Option 2: Minimum drainage efficiency of 90 percent as measured by ASTM E2273 or Annex A2 of ASTM E2925

Retrofitting buildings for energy efficiency includes significant upgrades to an existing building:

The design of a green retrofit should include significant building-envelope upgrades of all air-sealing and insulation systems, including the walls, foundation, roofing, doors, windows, and skylights. For example, installing StoTherm® ci Wall Systems Drainable EIFS can contribute tremendously to achieving a tight building envelope and to the goals of a deep energy retrofit.

The deep energy retrofit includes upgrades to heating and cooling systems: duct-system redesign, zoning, thermostat replacement, installation of on-demand heat pumps and water heaters, and use of energy recovery ventilation (ERV) systems.

Installation or upgrading of renewable energy mechanisms: small “hybrid” electric systems, solar photovoltaic (PV) panels, wind systems, or microhydropower.

A Deep Energy Retrofit of the Edgewater Condominiums, North Myrtle Beach, SC

Applying StoTherm® ci stopped water intrusion and improved the energy efficiency of this 260-unit condominium.

Applicator: Premier Exteriors
Architect: Construction Science and Engineering
Distributor: Capitol Materials Coastal
General Contractor: Prime South
Owner‘s Representative: Jason Smith

The entire building team for the green building retrofit of the Edgewater Condominium project worked together to develop the best solution to optimize the structure’s waterproofing and energy efficiency. They decided on the complete StoTherm system with a fluid-applied air and water resistive barrier and an adhered, drainable, continuously insulated system. The air and water resistive barrier serves as the first line of defense to stop moisture intrusion issues. In addition, the lack of fasteners prohibits potential moisture intrusion and thermal bridging.

The project involved the removal of all existing stucco. Applicators then reclad the structures with 250,00 ft2 of StoTherm® ci Lotusan® continuous insulation wall system. Applying the Sto system lowered the condominium’s utility bills and reduced upkeep to maintenance.

The Benefits of Deep Energy Retrofits

Retrofitting existing buildings offer many benefits to property owners and the environment:

Energy Savings

A retrofit home for energy efficiency can reduce energy use by 58 to 79 percent (depending on the home’s age and regional climate). Simple weatherization only cuts energy use by 10 to 20 percent.
Some deep energy retrofits achieve net-zero energy use, with homes and buildings producing as much energy as they use from on-site renewable resources.

Improved Indoor Air Quality

Indoor air contains about 2 to 5 times more pollution than outdoor air, a concerning health issue, considering many spend 90 percent of their time indoors. A home energy retrofit with improved ventilation systems helps control indoor temperature and humidity, both significant factors that affect indoor contaminant levels.

Enhances Indoor Environmental Quality (IEQ)

A deep energy retrofit contributes to excellent indoor environmental quality (IEQ) by creating comfortable, mold-free buildings and homes with controlled acoustics.

Lowers Maintenance Cost

Deep energy retrofits help to manage moisture and air infiltration in a building’s wall system to lessen the risk of corrosion and decay and significantly lower the cost of maintenance and repairs.

Lower Carbon Emissions

A deep energy retrofit can lower carbon emissions by 32 to 56 percent.

Higher Property Values

A deep energy retrofit increases a property’s resale value.

Energy Codes Guide Deep Energy Retrofit Buildings

Building codes help to guide builders, architects, engineers, and energy retrofit companies to design deep energy retrofits.

In the U.S. building teams use the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 90 and the International Energy Conservation Code (IECC) for design guidance of deep energy retrofits. Canadians can refer to the National Building Code of Canada (NBC) and the National Energy Code for Buildings (NECB).

Deep Energy Retrofit Cost

The costs of deep energy retrofit projects depend significantly on the project’s size and objectives. In addition, you can implement deep energy retrofit upgrades all at once or phase them in over several years, depending on your budget.

Planning a Deep Energy Retrofit to Optimize Energy Savings

To ensure financially successful deep energy retrofits, Sto strongly recommends hiring a skilled, experienced energy contractor to perform a professional energy audit and help you develop an innovative, energy-efficiency building retrofit program and solution to achieve your energy-saving goals.

In addition, a deep energy retrofit solution should include the whole-building approach and applying Building Energy Modeling (BEM).

Whole-Building Approach

Successfully retrofitting existing buildings involves a whole-building system approach that strives to use natural resources efficiently, lessen energy use, and enhance the building’s value. The whole-building system approach treats a building as a single energy system, where each component affects the entire building’s efficiency.

The design phase of retrofitting buildings for energy efficiency requires the building team, including the architects, builders, developers, and engineers, to collaborate and participate in all parts of the structure’s design and construction. In addition, they should select construction products and systems that use renewable energy sources and limit energy use.

Building Energy Modeling

Building Energy Modeling helps architects and builders optimize energy savings. BEMs use project-specific features like orientation, window location, weather, building methods and materials, and more. BEMs help to estimate a building’s energy efficiency and to meet energy codes. The BEM can also minimize building costs by identifying required insulation levels to achieve performance goals cost-effectively and offset costly, higher-quality envelope solutions by requiring a smaller HVAC system.

Sto’s All-In-One Continuous Insulation Wall System for Deep Energy Retrofit

A deep energy retrofit should include an application of continuous insulation (CI) in the exterior walls. Fortunately, energy-efficient, code-compliant exterior insulation and finish systems (EIFS), like StoTherm® ci Wall Systems Drainable EIFS, provide an all-in-one CI solution for achieving deep energy retrofit goals.

Restoring old buildings should aim to protect the property’s historical significance and aesthetics by preserving its original materials. However, components that are damaged beyond repair or do not meet current building codes, safety, and sustainability needs will require upgrading or replacement. In these cases, architects and builders should strive, as much as possible, to maintain the original aesthetics and character of the building.

For example, for old building facade replacement or restoration, Sto’s The A.R.T. of reStore® program provides an innovative solution for restoring old buildings’ facades to their original aesthetics. In addition, our products enhance a structure’s sustainability, safety, and occupant comfort level.

Preserving the Past By Old Building Restoration

The restoration of old buildings provides many cultural, economic, and sustainable benefits to a community; however, achieving these benefits successfully often requires the help of an experienced and qualified historic building restoration expert.

NOTE: Contact Sto Studio for design suggestions to help restore your historic old building with a high-performing, sustainable, aesthetically pleasing, and fully engineered cladding system.

Cultural Benefits of Restoring Old Buildings

Restoration of old buildings helps retain a community’s history, culture, aesthetics, and legacy for the current and future generations.

The National Historic Preservation Act (NHPA)

Nearly fifty years ago, the U.S. Congress recognized the cultural, educational, aesthetic, inspirational, sustainable, and economic importance of restoring old buildings to our country’s heritage by enacting the National Historic Preservation Act (NHPA).

After it passed, the Secretary of the Interior instituted the Standards for the Treatment of Historic Properties to direct the restoration of old buildings in America. Furthermore, National Historic Preservation Fund grant-in-aid projects must follow the Standards for the Treatment of Historic Properties, according to 36 CFR 68.

The Standards provide four approaches to treating historic old building properties: preservation, rehabilitation, restoration, and reconstruction. The treatment depends on the building’s historical significance, proposed use, physical condition, and planned interpretation. All approaches permit code-required work to make the old buildings functional, including upgrading mechanical, plumbing, and electrical systems.

Preservation

Preservation involves applying measures necessary to maintain the existing integrity, materials, and form of a historic, old building. The work includes steps to protect and stabilize the building, and focusing on ongoing maintenance and repairs of historic features and materials rather than extensive replacement and new construction and exterior additions.

Rehabilitation

Rehabilitation involves altering, repairing, and adding to an old building while preserving those features which convey its historical, architectural, or cultural values. Rehabilitation allows for replacing deteriorated parts; however, the replacements must match the original design, color, texture, and materials, if possible.

Restoration

Restoration depicts a property’s character, features, and form from a particular time. To achieve this, builders remove old, deteriorated building components, and replace them with new features that match the original design, color, materials, and texture.

Reconstruction

Reconstruction involves designing and building a new structure to match the building’s appearance from a specific historical time.

Economic Benefits of Restoring Old Buildings

• Encourages local businesses to grow and increases real estate values, which helps the economic viability of historic spaces.
• Allows architects and builders to include energy-efficient, durable building materials in the restoration design of old buildings.
• Rehabilitation often costs less than new construction.
• Existing usable space – faster occupancy.

Sustainable Benefits of Restoration of Old Buildings

Recycling of Building Materials

• Lessens the need for new materials to save natural resources
• Reduces landfill waste and construction, demolition, and hazardous material debris

Energy Savings

• Eliminates the use of energy for demolition and new construction
• Allows for reuse of embodied energy in building materials and systems
• Retrofitting allows for more energy-efficient products, like wall systems, windows, doors, etc.
