ExoAir® 110 is a composite 40-mil sheet designed for use as the membrane or as a component of an air barrier system. ExoAir 110 is 36 mils of self-adhering SBS rubberized asphalt laminated to 4 mils of white, cross-laminated, high-density polyethylene film and a siliconized release liner.
ExoAir 110 is an impermeable, self-adhered sheet designed to be applied to exterior cavity walls to mitigate air infiltration/exfiltration, vapor transmission and water penetration. ExoAir 110 is typically applied to exterior sheathing boards and concrete block, but can also be applied to poured concrete, steel and wood based substrates. ExoAir 110 also serves as a detailing or transition membrane into window and door openings. ExoAir 110 is designed to be installed when both the air and surface temperature are 30 °F (-1 °C) and rising.
