Securock ExoAir 430
Pre-Applied Synthetic Air & Vapor Permeable Membrane to Exterior Gypsum Sheathing
Securock ExoAir 430 (SE430) is an innovative building envelope solution that combines USG Securock® glass-mat sheathing with a factory-applied Tremco ExoAir® synthetic membrane. This all-in-one panel serves as a monolithic air and vapor-permeable barrier, streamlining construction schedules and reducing on-site labor while ensuring exceptional consistency and protection. Designed to control air, water, and vapor with a single application, SE430 is ideal for demanding commercial projects where speed and performance are critical.
