Innovative Metals Company recently introduced IntelliWrap PR permeable, self-adhering roofing underlayment to provide a water- and air-tight vapor-permeable barrier for a variety of roofing systems, including but not limited to standing seam metal, slate tile, clay tile and cedar shingle roofs. Designed for steep slopes (2:12 or more), IntelliWrap underlayment can also be used with lower-slope roofs.
Vapor permeability expedites the drying of building materials, significantly reducing the risk of moisture infiltration. In addition, IntelliWrap PR underlayment meets ASTM E2178 air-barrier resistance and is formulated to withstand temperatures as high as 250 F. It’s compatible with a wide range of substrates, including fiberglass-reinforced gypsum sheathing board, rigid insulation, concrete, plywood, steel, galvanized metal, aluminum and OSB.
