List of featured suppliers of ROOFING UNDERLAYS PITCHED ROOF MEMBRANES Non-Permeable Non Permeable on Building Products Index
Roofing underlays and pitched roof membranes are materials used in construction projects to provide a protective barrier between the roof deck and the weather elements. Non-permeable underlays are designed to be impermeable to water, preventing any leakage into the structure. These types of underlays are typically made of synthetic materials such as polyethylene or polypropylene, and are reinforced with woven or non-woven fabric. The non-permeable characteristic of these underlays also makes them ideal for use in areas with high wind loads or extreme weather conditions.
