Air/Water Barrier

Tremco Construction Products Group has launched the first collaborative system that combines two industry-leading products. The Dryvit® Outsulation® Plus MD, MD, PE, HDCI and X systems with the USG-Tremco® Securock® ExoAir®430 System have formed the ultimate air/water barrier for the building enclosure, covered with a 20-year warranty: the Outsulation Securock ExoAir 430 Systems.


Outsulation Systems, by Dryvit, place insulation on the outside of the building, resulting in energy efficient and cost-effective construction. Outsulation Systems combine exterior insulation and seamless finish veneers with a range of aesthetic options. The Securock ExoAir 430 System is a high-performance, energy efficient air/water barrier system comprised of USG Securock Brand UltraLight Glass-Mat Sheathing and Tremco ExoAir air/water barrier membrane. The membrane is applied in a factory-controlled setting, delivered to the job site with the membrane cured on the panel, ready to hang. Securock ExoAir 430 System eliminates challenges that can occur when applying an air/water barrier in the field. The combined Outsulation Securock ExoAir 430 Systems help project teams reduce construction costs while developing and building high-performing, energy efficient structures.


Under a single, premium and high-performance warranty, the entire system is covered from the studs through to the cladding. The Outsulation Securock ExoAir 430 Systems warranty offers 20 years of coverage.
