The Securock ExoAir 430 System is the first integrated gypsum sheathing panel with a factory-applied fluid air-barrier membrane. The panel brings two proven technologies together — USG’s Securock Brand Glass-Mat Sheathing and Tremco’s fluid applied air/water barrier membrane — into one panel that efficiently delivers an air barrier solution to the job site. 
The controlled application of this system eliminates issues that arise with field application, such as weather. Additionally, since the coating is applied to the wallboard in the factory, there is no need to wait to apply the air barrier onsite. This allows for the project to progress more quickly — saving both time and money.
