Air and water-resistive barriers are essential parts of moisture management of building enclosures. Their vapor permeability allows the building enclosure to dry, while water passing through the exterior cladding cannot migrate past these membranes due to their water penetration resistance. The membranes also contribute to energy efficiency by serving as an air infiltration barrier. Our comprehensive line of air and water-resistive barriers will provide you with an ideal solution for any type of wall assembly.
