PART # SG-209

The Tremco ExoAir 110AT Primerless – 12" Self-Adhered Air & Vapor Barrier Flashing is a high-performance membrane designed to protect building envelopes from air infiltration, vapor transmission, and water penetration. Engineered for professional construction applications, this 12-inch wide membrane is ideal for detailing, transitions, and smaller coverage areas where precision installation is required.

ExoAir 110AT is an impermeable, self-adhered sheet membrane that adheres directly to approved substrates without the need for primer in most applications, helping streamline installation and reduce labor time. It is commonly applied to exterior sheathing boards and concrete block as part of a continuous air and vapor barrier system. The advanced adhesive technology ensures strong, consistent bonding while maintaining durability in demanding environmental conditions.

In addition to sheathing and block, ExoAir 110AT can be applied to poured concrete, steel, and wood-based substrates. It is frequently used as a detailing or transition membrane at window and door openings, ensuring continuity of the air barrier system. By minimizing uncontrolled air leakage and moisture intrusion, this primerless membrane enhances energy efficiency, building durability, and long-term performance in commercial and residential wall assemblies.
