GCP Perm-A-Barrier Wall Flashing, 18" W x 75' L Roll

GCP 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, Perm-A-Barrier flashings prevent premature deterioration of the building envelope, enhance thermal performance of the structure, and save energy costs.
