Tremco Exoair 111

ExoAir 111 is a composite 24-mil sheet designed for use as themembrane or as a component of an air barrier system. ExoAir 111 is 20 mils of high-performance butyl laminated to 4 mils of metalized highdensity polypropylene film and a siliconized release liner.

Basic Uses

ExoAir 111 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.
