October 12, 2007—DuPont has launched DuPont RoofLiner with Elvaloy, the next roofing innovation for commercial and residential construction. DuPont RoofLiner with Elvaloy is a lightweight, high -performance roofing underlayment scientifically engineered to help provide superior durability and protection against leaks compared to roofing felt. The product offers superior tear resistance, excellent water holdout and six-month UV resistance, according to DuPont.
In addition, the product is engineered for use with all types of roofing materials identified by ICC-ES AC188, such as asphalt shingles, clay, concrete, fiber cement or metal tiles, slates, wood shakes, standing seam metal sheets and corrugated metal roofing. A major benefit of using a versatile and compatible product such as DuPont RoofLiner with Elvaloy is its ability to allow for easier, more efficient installation. One roll of DuPont RoofLiner with Elvaloy replaces five rolls of 30-lb. roofing felt and is five times lighter, according to the company.
