PART # SG-208

The Tremco ExoAir 110AT Primerless – 9" Self-Adhered Air & Vapor Barrier Flashing is a high-performance membrane designed for precise detailing and transition work within air barrier systems. The 9-inch width makes it ideal for smaller coverage areas, joint treatment, and integration around window and door openings where controlled application is essential.

ExoAir 110AT is an impermeable, self-adhered sheet membrane engineered to mitigate air infiltration, vapor transmission, and water penetration in exterior wall assemblies. Its primerless adhesive technology allows it to bond directly to approved substrates without the need for primer in most conditions, helping improve installation efficiency and reduce labor time. It is commonly applied over exterior sheathing boards and concrete block to maintain continuity of the air and vapor barrier.

In addition to sheathing and masonry, ExoAir 110AT adheres to poured concrete, steel, and wood-based substrates. Frequently used as a detailing or transition membrane, it ensures consistent performance at penetrations and system tie-ins. By reducing uncontrolled air movement and moisture intrusion, this 9" membrane supports energy efficiency, long-term durability, and overall building envelope performance in both commercial and residential construction.
