New Roofing Underlayment Adds Durability, Protection to Roofing System WILMINGTON, Del., Oct. 9 /PRNewswire-FirstCall/ -- As a leader in building material manufacturing, DuPont (NYSE:DD) has launched DuPont(TM) RoofLiner with Elvaloy(R), the next roofing innovation for residential and commercial construction. With the introduction of DuPont(TM) RoofLiner with Elvaloy(R), DuPont has taken another step in providing innovative building solutions for the roofing industry. Introduced in 2006, DuPont(TM) Tyvek(R) AtticWrap(TM), the first breathable roofing membrane to completely seal a home's building envelope, is specifically designed for a home's attic to create a continuously airtight space that prevents air and water intrusion and helps conserve energy. "As an industry leader, we are dedicated to staying ahead of building trends by offering products that increase the ease of installation, reduce customer call backs and meet building codes," Thomas F. Schuler, vice president and general manager -- DuPont Building Innovations, said. "DuPont(TM) RoofLiner with Elvaloy(R) gives builders and contractors an innovative solution for new roof installation as well as re-roofing applications." DuPont(TM) RoofLiner with Elvaloy(R) is a lightweight, high-performance roofing underlayment scientifically engineered to help provide superior durability and protection against leaks compared to roofing felt.
