USG and Tremco, two industry leaders, are bringing together two well-established products to deliver a truly innovative air/water barrier system. The Securock^® ExoAir^® 430 System is the only gypsum sheathing panel coated with a factory-applied fluid air barrier membrane to control air, water and vapor in a very efficient way. The system provides the air barrier continuity required via direct connections of the accessories to the membrane on the face of the panel. The flexible membrane promotes nail sealability, water drainage and durability for the life of the building. It also supports both energy-efficient design and speed of construction, delivering a highly predictable air barrier performance while simultaneously condensing the construction schedule.
