Sto Corp. Expands StoVentec® Fiber Cement Color Collections with New Mezzo Options

ATLANTA, GA (March 17, 2026): Sto Corp., the innovative world leader in building envelope solutions including wall cladding systems, air barriers, coatings, and restoration systems, announces the expansion of its StoVentec® Fiber Cement Rainscreen® System color palette with the addition the Mezzo collection. The expanded offering now includes three curated color collections and 17 total color options, giving architects and designers greater flexibility when creating distinctive façade designs.

StoVentec Fiber Cement is a complete ventilated rainscreen cladding system engineered by Sto to integrate seamlessly with all exterior wall components, providing enhanced performance, durability, and design versatility.

The three new Mezzo colors introduce subtle tonal variations inspired by natural materials. Ranging from light brown to dark gray, the additions complement contemporary architectural palettes while maintaining the balanced, organic character that defines the Mezzo collection. The panels feature through-body pigmentation, ensuring consistent color throughout the panel for improved durability and long-lasting aesthetics.

With the expanded palette, StoVentec Fiber Cement now offers three distinctive color collections:

  • Primara Line: A grey-bodied panel with an opaque surface finish and a smooth texture with a lightly sanded grain.
  • Mezzo Line: A refined collection blending organic texture with modern simplicity, featuring balanced tones and smooth finishes.
  • Strata Line: Panels with pigmented bodies and ultra-smooth finishes that create a sleek, contemporary aesthetic.

Beyond aesthetics, StoVentec Fiber Cement is designed to deliver high-performance building envelope protection. The rainscreen system integrates noncombustible continuous insulation, a robust air and water-resistive barrier, engineered sub-construction, and high-density fiber cement panels, providing durability and long-term weather resistance.

To accommodate diverse design preferences, StoVentec Fiber Cement panels are available with both concealed and visible fastening options, allowing architects to achieve either clean, uninterrupted panel surfaces or a more expressive façade aesthetic.

Sto also commissioned extensive testing to evaluate the durability of StoVentec Fiber Cement panels. Independent testing assessed indentation resistance, small hard-body impacts, and large soft-body impacts, demonstrating strong performance against everyday building impacts and wear scenarios.

For design professionals seeking streamlined specification and coordination, StoVentec Fiber Cement systems are also available in BIM, enabling architects to integrate the system directly into digital building models for improved project planning and documentation.

“StoVentec Fiber Cement continues to evolve to meet the design and performance expectations of today’s architects,” said Karine Galla, Director of Product Management. “The expanded color collections, combined with flexible fastening options and proven durability, provide architects with a rainscreen solution that delivers both creative freedom and reliable performance.”

Panels are available in standard sizes up to 4’ x 10’ and thicknesses of 8–10 mm and can be installed horizontally or vertically in stacked or staggered layouts to create custom patterns and façade expressions.

]]> Over-engineering. It happens more than you might believe. Often, it’s driven by good intentions, such as ensuring structural integrity and wind load resistance. Unfortunately, it’s all too common in traditional fiber-cement cladding systems. That’s because these older systems typically require 16″ on-center (OC) framing. Inches matter with stud spacing. Closer stud spacing increases material use and labor time. It also adds cost and complexity, especially in large facade applications.

As a leader in rainscreen innovation, efficiency and performance-based engineering, Sto has been actively working on solutions to overengineering, with a focus on fiber-cement applications. StoVentec® Fiber Cement is the result of those efforts.

StoVentec® Fiber Cement: A Smarter Structural Approach

StoVentec® Fiber Cement T-profile sub-framing component designed to support 24-inch on-center lean framing layouts

A forward-thinking solution that helps architects and contractors reduce overdesign and optimize facade performance, StoVentec® Fiber Cement offers unparalleled versatility and design freedom for your projects. As an extension of our trusted Rainscreen® systems, this durable, aesthetically flexible cladding solution empowers architects to create facades as unique as the buildings they design.

One of the design tools available with this system is the StoVentec Fiber Cement Design Guide and Detail Booklet. This powerful guide enables lean framing layouts with 24″ on-center spacing. That’s an 8” difference compared to traditional fiber-cement systems, reducing material requirements by up to one-third! The benefits of this lean framing approach are clear:

  • Material Efficiency: Fewer studs and connection points mean lower material costs and lighter wall assemblies without sacrificing performance or durability

]]> Fiber cement has been a common cladding material on job sites for decades. It has won over building owners with its innate ruggedness and architects with its design flexibility. However, a question has been lurking about fiber cement for quite some time. That question is: Does standard fiber cement cladding meet performance requirements in all climates?

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

Commercial building with sleek white fiber cement rainscreen panels demonstrating modern facade design and durability.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.

Sto’s StoVentec® Fiber Cement

]]> Properly installed liquid-applied air and water-resistive barriers (AWRB) provide all the applicable performance and installation requirements for air and water resistance. An AWRB helps protect the building and its occupants from damaging and unhealthy mold and rot. 

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.

]]> High-performing, drainable EIFS provides the building industry with a complete wall cladding system and a simple-to-use solution toward compliance with the current energy code. Drainable EIFS wall systems, like StoTherm® ci Wall Systems, include five control layers (vapor, air, water, thermal, and water shedding) that work together to create a tight building envelope to ensure an energy-efficient, durable, safe, sustainable, and attractive building. 

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.

]]> High-performing, elastomeric, one-part hybrid StoSeal STPE™ Sealant 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).

]]> Sealants are used to seal, block or close gaps between building materials to prevent fluids, air and other substances from passing through. The use of a high-quality sealant assists in creating a tight building envelope which improves energy-efficiency and occupant comfort of a building.

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 STPE™Sealant, 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 STPE™Sealant 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

]]> Applying a fast-cure sealant for joint sealant applications will accelerate construction timelines and increase productivity. Accelerating construction can help contractors and developers save money, avoid problematic weather delays, and even realize contract bonuses. Therefore, contractors should select time-saving methods and products, like fast-cure sealants, to keep a project on time, or to accelerate completion.

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.

Correctly applying a high-performing STPE joint sealant, like StoSeal STPE™Sealant, 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 post The Art of Exterior Design: A Guide to External Render Cladding Systems appeared first on Sto Corp..

]]> Rendered facades give a building a sophisticated and sleek look in a wide range of finishes, textures, and colors that will suit any budget and building style. Typically, render cladding systems refer to a coat of cement on a building’s exterior to create a smooth, textured, or patterned finish in an expansive range of colors.

However, complete external render cladding systems (like the StoVentec® Render Rainscreen® wall assembly) provide all the exterior wall system components (air and water-resistive barrier, insulation, sub-construction, and rendered facade panel) into one straightforward-to-install system, which will save builders money and time.

The StoVentec® Render complete Rainscreen® cladding system produces superior air and water resistance, excellent thermal performance, wind, fire, and impact protection, and attractive render aesthetics. Each component contributes to the building’s long-term integrity and indoor comfort, safety, and air quality.

What is Exterior Rendering?

Installers apply a render coating to a facade to create a smooth or textured surface, in order to improve a building’s aesthetics and extend the exterior wall’s lifespan.

Types of Render Finish

The success of a rendering project depends on choosing a suitable render material:

Lime Render

Breathable lime render expands and contracts without damage, and is particularly suited to older buildings that cannot use cement render.

Cement Render

Easy-to-apply, quick curing, and durable cement render prevents water damage and provides walls with added strength. However, its rigidity makes it prone to cracking, so installers typically avoid its use on older structures.

Acrylic Render

Acrylic render sets in just 24 hours, faster than other renders. Various aggregate sizes allow for a variety of aesthetic ranging from smooth to coarse

Monocouche Render

Installers often use easy-to-use, single-layer monocouche rendering on new houses and buildings.

Polymer Render

Installers often use polymer render, which allows the substrate to breathe on most wooden or brick buildings.

Other tips for successfully installing render include:

  • Mix the render with room-temperature water.
  • Do not apply in extremely hot weather because the render mix will set in too fast, and lead to cracks.
  • Do not apply in frigid weather because it will cause the render mix to slide down, and make it messy.
  • Mild-cloudy and rain-free days are the best days for using render.

Six Benefits of External Rendering

Properly applied external rendering can provide a building with several long-lasting, significant benefits. However, successful rendering depends on thoughtfully designing and hiring a reputable and skilled installer.

1. Protects a Property Against Rain and Wind

Exterior wall rendering is the first defense against harsh weather and moisture infiltration in a building’s envelope. It can also protect against mold and algae growth.

2. Enhances a Building’s Appearance

External render cladding creates a modern look of luxury. It can also hide unattractive-old brickwork, and give a building a crisp new appearance. Furthermore, rendering allows architects to combine additions to an existing building.

3. Adds Value to a Property

Render facades enhance a building’s curb appeal, which adds value to the property.

4. Cost-Effective Rendering

External rendering offers builders a cost-effective cladding solution. However, it depends on the render type, surface preparation, project location, project size, and the tradesman’s experience. To be cost effective, the climate zone and exposure must be taken into consideration. Opting for a higher end render can save money on the long run with superior durability and fading resistance.

5. Breathable Renders

The breathability of silicon and mineral render facades allows moisture generated from the indoors to evaporate to the outside, which helps to minimize condensation within the wall cavity.

6. Low-Maintenance

Low-maintenance, UV-stable, pre-colored renders can last up to 10 years depending on the climate zone and exposure. Using a super hydrophobic render will also reduce maintenance with its self cleaning properties. In addition, applying the render to a flexible-thin fiberglass mesh base layer allows it to move with the building, which makes it less prone to cracking.

StoVentec® for Render Facades

Queensbridge Quarter combined StoVentec® Render and Glass systems to deliver a stunning multi-family building in London.

The traditional method of installing render protects the exterior wall’s durability; however, on its own, it does not improve the building envelope’s thermal performance.

Fortunately, the ®StoVentec® Render Rainscreen® wall system is a complete, fully-tested, code-approved, back-ventilated wall system that provides a superior air and water-resistive barrier and strong mineral wool continuous insulation (CI).

In addition, the drained and back-ventilated StoVentec® Render rainscreen wall assembly offers the aesthetics of Stolit® Lotusan®, Sto textured finish, self-cleaning textured finish, and StoCast prefabricated resin cast shapes.

]]> Building enclosure systems include below-grade and above-grade portions of a structure that physically separates the interior from the exterior environment. The components of a building enclosure system include the:

Base floor systems
Foundation wall systems
Above-grade wall systems
Doors and windows
Roof systems

Each component provides a multi-material, multi-layer assembly that extends from the interior layer (wallpaper or paint) to the outermost exterior layer (roof shingles, facade). Together, all the adjoining enclosure sub-systems make up the enclosure system in architecture.

Building Enclosure Design Considerations

Optimizing the building enclosure’s performance requires quality building enclosure solutions, like Sto’s integrated building enclosure systems, that consider interior and exterior environments, loadings, physical functions, and performance attributes of the enclosure. These also apply to the other physical components of the building.

Interior and Exterior Loadings

Loading refers to any event or characteristic that affects the enclosure, typically related to:

Gravity
Ground
Heat (thermal)
Moisture
Air

Interior-Environment Loadings

Interior-environmental loadings mainly result from the occupants, natural occurrences, or conditioning. Managing interior-environment loadings involves space conditioning to maintain temperature and humidity levels and fire prevention. Therefore, the success of the building enclosure depends on addressing the interior environment.

Exterior-Environmental Loadings

Exterior environment loadings occur due to climate (weather, hurricanes, flooding), human (smog, global warming), or nature (fire, seismic, pests). Therefore a high-performing building enclosure must provide resistance against water, wind, fire, radon, flood, earthquake, termites, and hydrostatic pressure. The durability and long-term integrity of the building or home depend on a building enclosure with all these protections.

Building Enclosure Functions

Building enclosures provide three physical functions:

Support Functions resist, transfer, and accommodate all the structural forms of loading imposed by the interior and exterior environments, the enclosure, and the building, often acting as an integral part of the building superstructure.
Control Functions regulate and moderate all the loadings due to the separation of the interior and exterior environments – the flow of mass (moisture, air, etc.) and energy (sound, heat, UV, etc.).
Finish Functions of the enclosure surface ⎯ the envelope interfaces with the exterior and interior environments. Each interface must meet the relevant visual, aesthetic, durability, and other performance requirements.

Attributes of a High-Performing Building Enclosure

A high-quality building enclosure must manage every loading to ensure long-term, successful performance and include both physical and qualitative attributes.

Simple and quick construction
Durability and long-term integrity
Superior aesthetics
Sustainability
Safety to occupants
Low-maintenance and repair needs
Financial savings during and after construction

In addition, our building enclosure wall systems offer endless choices in styles, textures, and colors for creating aesthetically pleasing facades with eye-catching curb appeal. You can combine several facades in a single system without product compatibility design and transition challenges.

Building Enclosure Systems in Architecture

Sto building enclosure systems include control layers that protect the building from exterior environmental elements and also create a healthy, comfortable interior for the occupants.

  • An air barrier lessens energy use and condensation by limiting unwanted airflow through the wall system.
  • A permeable or impermeable (per designer specification) vapor retarder minimizes condensation by stopping the flow of water vapor as it moves from high to low-pressure areas.
  • A water-resistant barrier flashes to the cladding’s exterior to stop water from infiltrating the wall cavity.
  • A thermal barrier minimizes energy loss and stops thermal bridging.
  • A water-shedding and durable facade protects against weather, UV exposure, pollutants, and more.

Sto products are also dependability fortified by third-party testing and code compliance, including fire testing (NFPA-285). We cover all of our wall systems with a single-source warranty.

]]> A high-performance cladding system deflects, drains, and evaporates moisture on the outside and inside of the wall system and protects a building envelope from rain, snow, and other outside elements.

The design of the cladding system must ensure durability, sustainability, and energy efficiency. The building cladding influences the look and feel of the surrounding area, so it should give visitors a memorable first impression of the building.

What is a Cladding System?

What is a Cladding System?

The building cladding refers to all the building components that are attached to its primary structure (parts that keep it standing), that form the external, non-structural surfaces. Often, cladding attaches to the building’s structural frame as prefabricated panels, whether it’s cladding systems for high-rise buildings or residential homes.

High-Performance Cladding Systems

A high-performing cladding for buildings provides more than just a building’s exterior facade and aesthetics. Quality building cladding systems:

  • Protect the structures from external elements (rain, snow, wind, ice)
  • Minimize the spread of fire
  • Provide thermal insulation to create air tight building envelope to manage the inside environment
  • Transfer impact and wind loads to the structural framework
  • Provide privacy and security and prevent the transmission of sound
  • Provide openings for ventilation, daylight, and access

Properly-installed, high-quality, well-designed cladding materials for buildings minimize air leakage, maximize thermal performance, and optimize natural daylight. These features lessen the need for electrical and mechanical systems and contribute toward a sustainable, energy-efficient, safe, and durable building.

The Four D’s of High-Quality Cladding Systems

High-quality cladding systems must provide consistent deflection, drainage, drying, and durability:

  1. Drainage refers to cladding materials’ capacity to allow water that gets behind the outer surface to drain. Applying a water-resistant barrier over the sheathing and a drainage gap between the sheathing and the cladding can provide adequate drainage. However, stucco cladding, which can’t handle large volumes of water, often needs enhanced drainage, requiring a drainage mat to increase the space between the cement membrane and WRB. The space permits more accessible water flow down and out from within the cladding.
  2. Deflection refers to the cladding’s ability to consistently deflect ice, snow, and rain that attacks the outside wall surface. In addition, you can assist the water deflection with gutters and overhangs.
  3. Drying refers to a cladding system’s permeability or ability to permit ventilation within the system to encourage drying. Building codes often require vapor-permeable exterior cladding to permit moisture or condensation to travel through it as a vapor when heated by the sun. Including open space at the top and base of the wall cladding will allow airflow and additional drying.
  4. Durability refers to the cladding system’s ability to resist continuous exposure to ultraviolet (UV) rays, thermal contraction and expansion, and wetting-and-drying cycles. Durable cladding systems will help stop leaks and protect the building envelope’s integrity.

Other essential features to consider when choosing a high-performance cladding system include:

  • Ease of installation
  • Continuous insulation, adequate airtightness, and control of thermal movement
  • Low-maintenance
  • Fire resistance

Our tested systems at Sto also ensure that all components work together as mandated by today’s building codes:

  • Sto high-performance wall systems provide air leakage below 0.04 cfm/ft2 at 1.57 psf (0.2 L/s•m2 at 75Pa) when tested according to ASTM E2357 – a feature that potentially saves 40 percent in cooling and heating costs.
  • Sto’s wall cladding’s high R-value ( e.g. StoTherm® has an R-Value of 3.6 per inch) limits thermal bridging and lessens energy use. 
  • Sto products achieve a Class A rating when tested in accordance with ASTM 84 for Flame Spread and Smoke Development.
  • Sto walls have achieved several sustainable credentials:
    • Manufactured in ISO 9001 (Quality) and ISO 14001 (Environmental)  certified factories
    • SCAQMD (South Coast Air Quality Management District) VOC requirements
    • C-ES durability and fire protection criteria
  • Sto wall systems that contain combustible insulation or other combustible elements meet the requirements of:
    • NFPA 268 fire testing, which offers a method to assess the chance for a fire in one building to ignite a nearby building.
    • NFPA 285 fire testing, which evaluates the fire performance of wall assemblies with combustible insulation or other combustible components in noncombustible construction.
    • ASTM E 119 fire testing, which establishes the hourly fire-resistance rating of the wall assembly.

The post 5 Cladding Systems for High Performance Buildings appeared first on Sto Corp..

]]> A high-performance cladding system protects a building envelope from rain, snow, and other outside elements, by deflecting, draining, and evaporating moisture on the outside and inside of the wall system.

The design must ensure the building cladding systems’ durability, energy efficiency, and sustainability. The cladding’s aesthetic appeal for high-rise buildings or modest homes provides the structure’s first impression and influences the feel and look of the surrounding environment.

What Is a Cladding System?

The building cladding refers to all the components attached to the building’s primary structure (parts that keep a structure standing), and form the non-structural, external surfaces. Often, cladding attaches to the structural frame of the building as prefabricated panels.

A high-performing cladding system provides much more than just a building’s exterior facade and aesthetics. Quality cladding systems:

  • Transfer wind and impact loads to the structural framework
  • Protect the structures from external elements (rain, wind, snow, ice)
  • Provide thermal insulation to create an airtight building envelope, to control the inside environment
  • Provide security and privacy, and prevent the transmission of sound
  • Limit the spread of fire
  • Provide openings for daylight, ventilation, and access

High-quality, properly-installed, and well-designed cladding materials for buildings minimize air leakage, maximize thermal performance, and optimize natural daylighting. These features lessen the need for mechanical and electrical service, and contribute towards a sustainable, energy-efficient, safe, and durable building.

The Four D’s of High-Performance Cladding Systems

High-performance cladding systems must provide effective deflection, drainage, drying, and durability:

  1. Deflection refers to an exterior building’s cladding’s ability to deflect rain, ice, and snow that hits the outer wall surface. Designers can assist the cladding’s water deflection with overhangs and gutters. 
  2. Drainage refers to cladding materials for buildings’ capacity to permit water that finds its way behind the outer surface to drain. Architects and builders can handle this with an application of a water-resistant barrier over the sheathing and a drainage gap between the sheathing and the cladding. However, stucco cladding, which can’t deal with large volumes of water, requires enhanced drainage that uses a drainage mat to increase the space between the WRB and cement membrane. The space allows more accessible water flow down and within the cladding.
  3. Drying refers to a cladding system’s permeability or ability to allow ventilation within the system to encourage drying. Building codes typically require vapor-permeable exterior cladding, to allow moisture or condensation to pass through it as a vapor when warmed by the sun. Including open space at the base and top of the wall cladding will allow airflow and additional drying. 
  4. The durability of a cladding refers to the system and its components’ ability to withstand continued and repeated exposure to ultraviolet rays, thermal expansion and contraction, and wetting-and-drying cycles. Durable cladding systems will help prevent leaks and protect the building envelope.

However, other vital features you should consider when selecting a high-performance cladding system include:

  • Sufficient airtightness, continuous insulation, and control of thermal movement
  • Fire resistance
  • Low maintenance
  • Ease of installation

]]> Architects refer to a building’s exterior wall as its facade. Architectural facades set the building’s style, from a unique facade with glass cladding and asymmetrical windows to a welcoming facing with warm brick, expansive windows, and a large porch. The facade for today’s incredible buildings must also act as the primary barrier against rain, ice, snow, wind, sun, etc., to lessen maintenance and repair costs, lower energy consumption, and improve the indoor environmental quality (IEQ).

Considerations for Building a High-Performance Architectural Facades

A building’s facade architecture design impacts the building’s energy efficiency, durability, and the occupant’s experience. The facade you choose will affect your building costs, long-term maintenance, and utility expenses. 

We offer five considerations when building a high-performance architecture facade:

Energy Efficiency and Sustainable Facades

The facade’s design and how much you implement active and passive strategies will dramatically impact the energy use of your building. Architects can significantly lessen energy costs by utilizing sustainable facade strategies and materials, like those offered by Sto Corp. 

We commit to providing sustainable, safe, and healthy products and services, emphasizing long-term protection for our communities and planet.

Embodied Carbon

Choosing building products that reduce embodied and emitted carbon can reduce your building’s embodied energy by 80 percent. Fortunately, the engineering of Sto’s innovative wall systems reduces carbon emission through durability, energy efficiency, recycling, and the retrofitting of existing building stock as an aesthetic, economical, and energy-saving sustainable alternative to new facade construction.

Durability

A durable facade will maintain its integrity and aesthetics over time, by resisting wind, impact, fading, rain, snow, pollution, ice, hail, etc. A damaged or deteriorated facade can allow water to penetrate, which can lead to severe structural damage.

Acoustic Comfort

Background noise can significantly deteriorate one’s concentration ability and impact a business’s productivity. Facades that contribute to a building’s acoustic comfort by reducing exterior noise will improve the building’s work environment.

Impact on Daylight and Views

The windows of a building’s facade should add to the building’s beauty and also provide daylight and natural ventilation to the occupants. Workers with window views perform 10 to 25 percent better on memory and mental health tests and 6 to 12 percent quicker than employees in windowless rooms.

9 Unique Facade Construction Design Ideas

Interesting building facades represent an architect’s creative vision to give a building life, character, and personality. Sto Corp offers many products and systems to create sustainable, durable, inspiring, and thought-provoking wall envelope solutions with beautiful commercial building facade design.

Architect: Jeffrey Cole Architects
General Contractor: Source Construction Management, LLC

The original elegant porcelain tile facade of this seven-story, seven-unit, residential building was replaced. Large voids had formed due to improper installation, allowing water to seep into the structure. The architect and builder agreed that applying a new facade, using StoTherm® ci with Stolit® Milano, provided the best solution for simulating the ultra-smooth finish of the porcelain tile, and could mimic the grout lines with precisely drawn trowel marks. Installation of the facade:

  • First, they applied a layer of Sto Gold Coat®, fluid-applied air and moisture barrier over the original substrate and mortar. Sto designed vapor-permeable, fluid-applied Sto Gold Coat® for application under ci wall systems. 
  • Next, a layer of StoTherm ci EPS rigid foam, intended for use in Sto ci Wall Systems, provided a smooth surface to apply the final finish. It also boosts the building’s energy efficiency.
  • They applied the topcoat of Stolit Milano with a porcelain finish.
  • To match the appearance of the original porcelain tile, they used a trowel to score the joints, in order to replicate the look of grout joints.

An air barrier resists air leakage through the building envelope. In doing so it saves energy, minimizes the risk of condensation, and improves occupant comfort. Learn more.

Is it more important for the air barrier or vapor barrier to be continuous?

Both should be continuous, however, one can argue that continuity of the air barrier is more important because it “cuts off” air leakage paths that can result in significantly higher amounts of condensation than that caused by the same discontinuity in a vapor barrier. To learn more about Sto’s StoGuard® family of air and moisture barrier products, click here.

What are the types of moisture barriers?

Moisture barriers can be fluid-applied , self-adhered, or mechanically attached membranes. They are often referred to as air and water-resistant barriers (AWRBs).

Fluid-applied coatings can be found under the StoGuard® family of products furnished by Sto Corp. Self-adhered membranes are offered under the StoShield product line. To learn more about Sto air and water-resistant barriers click here.

What is a water resistive barrier?

A water-resistive barrier (WRB) is a term used in building codes to identify a material that is used to protect “water-sensitive” sheathing such as gypsum sheathing or wood-based sheathing. To learn more about Sto’s StoGuard® family of air and moisture barrier products, click here.

Is a vapor barrier the same as waterproofing?

No. Vapor barrriers resist the diffusion of water vapor (gaseous form of water), while waterproofing prevents water in liquid form from penetrating though it. To learn more about Sto’s StoGuard® family of air and moisture barrier products, click here.

What is the purpose of a moisture barrier?

A moisture barrier typically resists the passage of liquid water through it to prevent water damage to underlying materials or construction. To learn more about Sto’s StoGuard® family of air and moisture barrier products, click here.

What is the difference between vapor barrier and moisture barrier?

A vapor barrier resists the diffusion of water vapor (gaseous form of water) while a moisture barrier resists the passage of water in liquid form. To learn more about Sto’s StoGuard® family of air and moisture barrier products, click here.

Is a moisture barrier necessary?

Generally a moisture barrier is presribed in building codes for use over “water-sensitive” components of wall construction such as gypsum sheathing and wood-based sheathing and is therefore necessary in these situations unless other means are provided to protect these components. Generally a moisture barrier is not prescribed over “non-water sensitive” components of wall construction such as concrete or concrete masonry. However, it can be specified for use over these components for added moisture protection and/or if the moisture barrier is designed to perform other functions such as air leakage resistance (air barrier) or water vapor diffussion resistance (vapor barrier). StoGuard® products provide a variety of air and moisture barrier solutions depending on climate, substrate and desired application method. Learn more.

Sto HVHZ Systems

Do Miami-Dade County NOAs work in conjunction with the Florida Building Code?

Yes, A Florida Product Approval Number can be used statewide while the Miami-Dade NOA is a local approval for both Miami-Dade and Broward Counties. Sto has both Miami-Dade NOAs and FBC tested and listed High-Velocity Hurricane Zone (HVHZ) systems.

Do direct applied soffits (StoQuik Finish for Soffits and Ceilings) require NOAs or FBC approval?

No. Section 1626.1 of the FBC indicates that soffits are exempt from the impact test requirements for HVHZs.

Do “returns” where windows are set back into the wall requires NOAs?

The code does not specifically address this kind of detail, however, it is reasonable to assume this area would be considered part of the exterior walls and would therefore be subject to missile impact testing as required by the code, unless specific exemption is provided by the AHJ (Authority Having Jurisdiction)

What is the difference in application between Sto EIF Systems over gypsum sheathing with Large Missile (LM) and Small Missile (SM) NOAs?

The primary difference is Large Missile (LM) NOAs have an additional 20oz. Sto Armat XX mesh embedded in Sto base coat applied to sheathing. This application is used up to and including the first 30 feet in height of the project prior to the StoGuard air & water-resistive barrier (AWRB) application. The Small missile (SM) area (above 30 feet) doesn’t require the Sto Armat XX and Sto base coat on the sheathing before the StoGuard AWRB is applied.

How important is it to use all the Sto tested products in the NOA selected?

It is required by Miami-Dade and Broward Counties to use all the components listed in the tested NOA unless otherwise specified by Miami-Dade Product Control.

If an NOA is specified outside of these two counties the Local Building Code Official or Authority having Jurisdiction would need to give written approval for any variance.

Can you use Sto EPS Insulation Board or Sto GPS Board with the Sto NOAs?

Yes, all the applicable Sto NOA’s can use either Sto EPS Insulation Board or Sto GPS Board.

Can you use all the StoCast finishes with any of the NOAs?

Yes, StoCast Finishes can be applied per their product instructions as a finish in any of the applicable NOAs.

Can I use a stucco that isn’t a Sto Powerwall stucco in any of the StoPowerwall Stucco NOAs?

No, The NOAs were established based on testing with a StoPowerwall Stucco. Using another stucco would not be compliant with the NOA.
