30 High Performance Cladding Systems

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

Sto High-Performance Cladding Systems

Sto offers various simple and quick-to-install, high-quality cladding systems that meet the requirements for water drainage and deflection, permeability, airtightness, fire resistance, low maintenance, and long-lasting durability, to preserve a building’s integrity for its lifetime. We cover every feature of our wall systems under a single-system warranty.

Our systems combine all of the wall components into one tested, code-compliant system: continuous thermal insulation, air and water-resistive barrier, and endless aesthetic façade surface choices to meet all the needs of your design. In addition, you can combine several facade aesthetics into one system without transitions and product compatibility design difficulties.

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.
