Vapor Barrier Membranes

A vapor barrier membrane is a flexible and thin material that is used for damp proofing to prevent water vapor from diffusing in the floor, wall, or ceiling. Pittwrap and Insulrap are self-sealing vapor barrier membranes that are available in both 30 mil and 50 mil thicknesses. These products are designed to be used as moisture and vapor retarders with an insulated piping system. Vapor barrier membranes can be purchased in rolled form or can be applied to some of our fabricated goods. View our selection below!
