Today’s designers, architects, contractors, and building owners demand high-performing complete wall systems that combine multiple aesthetics with a high-performing building envelope, typically achieved with various control layers, like those offered by Sto Masonry Veneer Engineered Systems (MVES). Durable and aesthetically appealing masonry makes it an ideal cladding in many construction types. As exterior designs increasingly include combinations of multiple aesthetics, the compatibility and continuity of the building envelope are crucial to achieving a high-performing and long-lasting building. Today’s architects, builders, and building owners demand more than aesthetics.
Sto Masonry Veneer Engineered Systems (MVES) offer solutions allowing designers to achieve the look and performance they seek. These systems also allow for a vast array of building facade textures and colors while maintaining a continuous building envelope to help ensure a sustainable, energy-efficient building.
Sto Masonry Veneer Engineered Systems
Sto Masonry Veneer Engineered Systems (MVES) are fully engineered and tested systems that include the various control layers of the building envelope to ensure compatibility for a long-lasting, durable structure. Sto performed rigorous system-level structural, fire, and wind-load testing to ensure code-compliant and high-performing systems for any construction type.
All Sto’s MVES include the following components:
StoGuard® Air and Water-Resistive Barrier
The StoGuard® Air and Water-Resistive Barrier provides long-term protection against moisture intrusion and promotes excellent indoor air quality, unlike building wrap typically used in traditional masonry cladding, which can tear, puncture, or rip.
StoColl
High-performing, polymer-modified StoColl Portland cement thin set masonry veneer adhesive provides superior freeze-thaw resistance and high bond strength.
MVES Allows for Multiple Facades to Single System Designs
Sto Masonry Veneer Engineered Systems (MVES) allows architects and builders to apply a combination of masonry veneers like thin brick, natural stone, cultured stone, or ceramic tiles, along with a vast array of colors and textures coatings provided by Sto’s high-performance finishes, to their fully engineered and tested systems. The system type depends on the building’s performance needs (e.g., a continuous insulation system (EIFS), traditional stucco, cement board stucco, or rainscreen systems)).
Sto’s EIFS, stucco, cement board stucco and rainscreen systems include StoTherm® ci MVES, StoPowerwall DrainScreen MVES, StoQuik Silver DrainScreen MVES, StoPowerwall ExtraSeal MVES, and StoVentec for masonry veneer facades.
The systems provide several significant benefits:
- Durability
- Water and vapor protection
- Complete compatibility with other Sto architectural surfaces or systems
