ExoAir® 110AT is a 22-mil composite impermeable membrane that is comprised of 16 mils of butyl and 6 mils of HDPP facer. It can be used as the membrane, detailing accessory, as well as thru-wall flashing of an air barrier system. ExoAir 110AT when installed properly as a system will provide the requirements of an air barrier: air impermeable, continuity, structural integrity and durability.
ExoAir 110AT is an impermeable, self-adhered sheet designed to be applied to exterior cavity walls in order to mitigate air infiltration/exfiltration, vapor transmission and water penetration. Typically applied to exterior sheathing boards and concrete block, ExoAir 110AT can also be applied to poured concrete, steel and wood based substrate as well as serve as detailing or a transition membrane into window and door openings.
