The Securock ExoAir 430 system is an integrated gypsum sheathing panel with a factory-applied fluid air-barrier membrane. The panel brings two technologies together—USG Securock-brand glass-mat sheathing and a fluid applied air/water barrier membrane from Tremco (Beachwood, OH). The controlled application of the system is said to eliminate issues that arise with field application, such as weather. Since the coating is applied to the wallboard in the factory, there is no need to wait to apply the air barrier onsite.
