Air & Vapor Barrier - Self-Adhering Membranes
Perm-A-Barrier® Wall Flashing
Perm-A-Barrier® Wall Flashing is a 40-mil, self-adhesive flashing for cavity wall applications. Consisting of 32 mil of rubberized asphalt integrally bonded to an 8 mil, high-density, cross laminated polyethylene film, Perm-A-Barrier® Wall Flashing is designed to be strong and thick enough to resist punctures and tears. The unique self-sealing and self-adhesive characteristics of the rubberized asphalt allow it to resist leaks from minor cuts while providing a flashing solution that self-adheres to concrete, masonry, steel, gypsum and wood substrates.

Perm-A-Barrier® Wall Membrane
Perm-A-Barrier® Wall Membrane is a tough, self-adhering, self-healing waterproofing membrane for air and vapor barrier applications. Consisting of 36 mil. of rubberized asphalt integrally bonded to 4 mil 0.1mm (.004 in), high density cross laminated polyethylene film. 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. It is designed to be a cost-effective system providing a continuous seal against air, vapor and moisture around the entire building.
