Perm A Barrier® Detail Membrane
Bituminous and butyl sealant
Perm-A-Barrier® Detail Membrane is ideal for protecting and sealing critical areas of the building superstructure from the damaging effects of the elements. By minimizing air and water vapor flow through the building exterior at transition areas, Perm-A-Barrier Detail Membrane seals transition and detail areas to provide a continuous air barrier and Prevents premature deterioration of the building envelope. Perm-A-Barrier Detail Membrane is part of the full Perm-A-Barrier system for commercial applications.
