MFM Building Products Corp. Ultra HT Wind & Water Seal® 600x300

Ultra HT Wind & Water Seal® is a 45 mil, self-adhering roofing underlayment composed of a white, non-slip, cross-laminated polyethylene film, laminated to a high-temperature rubberized aggressive asphalt adhesive. The product is engineered for whole roof protection under shingle, tile, shake and metal roofing systems.
