All-in-One Sheathing and Air Barrier Speeds Construction
The Securock ExoAir 430 system combines USG’s gypsum sheathing with a factory-applied air-and-water barrier from Tremco for jobsite quality control.

Proper air-barrier installation requires careful application and attention to detail, and controlling the quality of liquid membranes and sealants applied to gypsum sheathing onsite can be particularly challenging. To simplify the process, USG and Tremco have teamed up to offer the Securock ExoAir 430 building envelope system.
The system takes USG’s fire- and mold-resistant Securock glass-mat-faced gypsum sheathing and factory coats it with with Tremco’s vapor-permeable ExoAir 230 air- and water-resistant-barrier. Add Tremco’s accessory sealants, and Securock ExoAir 430 provides a one-stop, packaged building envelope system that should speed installation and provide several other performance and environmental benefits.
