PART # SG-203

The Tremco ExoAir 110AT Primerless – 4" Self-Adhered Air & Vapor Barrier Flashing is a narrow-width membrane engineered for detailed air barrier sealing and transition work. The 4-inch width is ideal for seam treatment, sheathing joints, penetrations, and tight application areas where precise installation is required.

ExoAir 110AT is an impermeable, self-adhered sheet membrane designed to control air infiltration, vapor transmission, and water penetration in exterior wall assemblies. Its advanced primerless adhesive technology allows for direct bonding to approved substrates in most conditions without the need for separate primer, helping reduce labor time and improve installation efficiency. It is commonly applied to exterior sheathing boards and concrete block to maintain a continuous air and vapor barrier system.

In addition to sheathing and masonry, ExoAir 110AT adheres to poured concrete, steel, and wood-based substrates. The 4" width is especially suited for detail work around window and door openings, control joints, and system transitions. By minimizing uncontrolled air movement and moisture intrusion, this membrane enhances energy efficiency, protects structural components, and supports long-term building envelope performance.
