The Securock® ExoAir® 430 System is comprised of an air/water barrier membrane factory-integrated with a gypsum sheathing panel. The panel is a glass mat-faced, moisture- and mold-resistant gypsum panel, with a non-combustible core integrated with a factory-applied synthetic vapor permeable air/water barrier membrane. The outcome is a uniform membrane with superior bond resulting in predictable air and water barrier performance and adhesion to the base panel. The panel is a component of the Securock® ExoAir® 430 Air Barrier System, to be installed using Tremco sealants and transition membranes to achieve air barrier continuity.
