Perm-A-Barrier Aluminum Wall Membrane is a tough, self-adhering, self-sealing waterproofing membrane for air and vapor barrier applications. Consisting of rubberized asphalt integrally bonded to aluminum faced high density cross laminated polyethylene film. Perm-A-Barrier Aluminum Wall Membrane provides extended UV exposure and improved sealant adhesion to the film. Perm-A-Barrier Aluminum Wall Membrane, when combined with a structural substrate, produces a continuous air, vapor and water barrier on concrete, masonry, gypsum board and wood walls.
Perm-A-Barrier® Aluminum Wall Membranes are ideal for protecting the building superstructure from the damaging effects of the elements. By minimizing air and water vapor flow through the building exterior. It prevent premature deterioration of the building envelope. Enhance thermal performance of the structure and save energy costs. Its an improve comfort for the building occupants.
