Perm-A-Barrier Wall Membrane is a tough, self-adhering, self-sealing waterproofing membrane for air and vapor barrier applications. Consisting of rubberized asphalt integrally bonded to high density cross laminated polyethylene film. It is designed to be a cost-effective system providing a continuous seal against air, vapor and moisture around the entire building. Perm-A-Barrier Wall Membrane, when combined with a structural substrate, produces a virtually impermeable air, vapor and water barrier on concrete, masonry, gypsum board and wood walls.
Perm-A-Barrier® 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. Perm-A-Barrier Wall Membrane is enhance thermal performance of the structure and save energy costs. It Improve comfort for the building occupants.
