The only air barrier system that combines glass-mat sheathing with a factory-applied fluid air barrier membrane into one panel.
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
Air barrier membrane is pre-applied on the outside of the sheathing panel where it can 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 throughout the entire building
Intentional disruption to address air barrier installation challenges, such as inclement weather and variability in 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
10-year performance warranty for the system, 15-year material warranty for the panel, and 20-year warranty for the Outsulation® Securock® ExoAir® 430 Systems
