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, or as through-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.
