The Securock® ExoAir® 430 System brings two proven technologies together—USG Securock® Brand UltraLight Glass-Mat Sheathing and Tremco ExoAir® air barrier membrane—into one panel that efficiently controls air, water, and vapor throughout the building envelope.
Factory application of the air barrier ensures membrane uniformity and adhesion to the base panel, saving time on the jobsite
The air barrier membrane is positioned on the outside of the sheathing panel where it can do its job—act as the drainage plane and stop bulk water
Full system of products that have been tested for chemical compatibility to make the critical connections of the entire building
Intentional disruption to address industry challenges, such as installing an air barrier during inclement weather and eliminating variability in air barrier field application
Documented system performance goes beyond industry requirements, providing architects the confidence to specify and building owners the performance they demand. All system components have been tested for adhesion, compatibility, air leakage, and water penetration as an assembly and will perform when properly installed in the Securock ExoAir 430 panel assembly.
Warranties & Training
15-year material warranty for the panel and 10-year performance warranty for the system
