ExoAir® 220 


Tremco. Inc.

ExoAir® 220 Fluid-Applied Vapor-Permeable Air Barrier Membrane is a single-component, elastomeric asphalt emulsion membrane designed to be rolled or sprayed on exterior above-grade wall assemblies. Once dried, it creates a durable, monolithic membrane. ExoAir 220 is a weather-resistive air barrier designed to control the flow of air and liquid water through the wall assembly. It will allow water vapor to pass through the coating. It can be applied to most common building materials including, but not limited to, exterior sheathing boards, concrete masonry units (CMU), concrete, steel and wood surfaces. ExoAir 220 is used in conjunction with other accessories to provide a comprehensive air barrier system.
