Multi-Purpose Transition Membrane
ExoAir® Duo Membrane is comprised of a tear-resistant fabric embedded into a polyethylene copolymer. The unique design provides a reactive membrane that changes its water vapor permeability depending on temperature and relative humidity. This allows the product to perform as an intelligent seal for airtight and weathertight internal and/or external joints.
The ExoAir Duo Membrane is primarily used to seal window and door perimeter joints in both commercial and residential applications. ExoAir Duo Membrane can be installed onto vinyl, HDPE, wood, plywood, OSB, concrete, aluminum and other typical construction substrates.
