5/8 in x 4 ft USG Securock ExoAir 430 System

Introducing the Securock® ExoAir® 430 System—the first integrated gypsum sheathing panel with a factory applied fluid air barrier membrane. The panel brings two proven technologies together—USG Securock® Brand Glass-Mat Sheathing and Tremco’s fluid-applied air/water barrier membrane into one panel—that gives you an efficient delivery of the air barrier solution to your job site.

The controlled factory application of the membrane to the face of the panel provides the assurance that only a traditional thick-film membrane can. The system provides the continuity with a direct connection of the sealant to the membrane, giving you the visual verification to install with confidence.
