Procheck 300 is a lightweight, reinforced, polyethylene vapour control layer for use within roof and wall constructions to prevent warm, moist air escaping from inside the building and condensing within the insulation. The woven, polypropylene, multifilament scrim reinforcement provides excellent resistance to tears and punctures to withstand tough site conditions
and is unaffected by chlorine.
