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.
