Product Data Sheet

ExoAir® 210AT is a self-adhered permeable air barrier membrane that is comprised of 21 mils high performance acrylic adhesive and a nonwoven facer. When installed properly as a system, ExoAir 210AT will mitigate air infiltration/exfiltration and water penetration while remaining permeable to the passage of water vapor.

Features & Benefits

• The high-performance acrylic has been tested and is compatible with the ExoAir product line.
• Primerless application allows for faster installation time.
• Manufactured to a preset, uniform thickness that provides consistent and uniform coverage.
• The high-performance properties of the ExoAir 210AT membrane retard the migration of air and bulk water but allow water vapor to pass through the membrane. As a result, vapor permeable systems like ExoAir 210AT allow for more flexibility in the placement of the air barrier membrane in the wall design.
