Waterproof fabric membrane WBM111

Description Waterproof breathable membrane is three layers thermal lamination. Polypropylene (PP) non-woven fabric layer is on the top and bottom for protection and reinforcement, and micro-porous polyethylene (PE) film is in the middle as breathable membrane. The membranes are commonly used as waterproof underlay beneath the roof covering, which is impervious to rains or snows, meanwhile they are vapor permeable and allow the moisture escape from the roof structure to avoid mold and rot of fiberglass or insulation or wood structure, and keeping excellent R-value. Features - Excellent water resistance, vapor permeability and good tensile strength - Strong tear and nail strength and flexibility at low temperature - Lighter weight, easy to handle Uses * As underlay for roofs and walls of new buildings or renovations * As waterproof and vapor permeable barriers for protection insulation layers of walls or roofs * Used as a temporary waterproofing barrier during the construction process
