Ideal for both new and retrofit applications, Perm-A-Barrier® Wall Flashing is a 40-mil through wall membrane designed to collect water entering wall cavities and direct it to the exterior through the wall’s weep system. Perm-A-Barrier Wall Flashing is a 40 mil (1 mm) self-adhesive, cold-applied sheet consisting of 32 mil of rubberized asphalt integrally bonded to an 8 mil, high density, cross-laminated polyethylene film. The rolls are inter-wound with a disposable silicone coated release sheet. Perm-A-Barrier can be applied to concrete, masonry, block, steel, gypsum and wood and is highly effective even on vertical surfaces and around details.
Available in 75’ rolls in widths of 18”, 24” and 36”.
