PW 100/40 Air/Vapor Barrier
Description
A peel and stick membrane for use as a positive air/vapor stop in everyday construction. Our product is a 40 mil SBS modified rubberized asphalt sheet waterproofing membrane that fully bonds to most substrates through the primer course. It is a white, polyethylene-topped, membrane that has excellent conforming capabilities to irregular surfaces. PW 100/40 is compatible with and will adhere to steel, wood, concrete, building paper, block wall, dry wall and insulation board. PW 100/40’s paper release backing, and the variety of roll widths, contributes to the ease of application.
