New Roofing Underlayment from Dupont Adds Durability, Protection to Roofing System

As a leader in building material manufacturing, DuPont has launched DuPont RoofLiner with Elvaloy, the next roofing innovation for residential and commercial construction. With the introduction of DuPont RoofLiner with Elvaloy, DuPont has taken another step in providing innovative building solutions for the roofing industry. Introduced in 2006, DuPont Tyvek AtticWrap, 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 RoofLiner with Elvaloy gives builders and contractors an innovative solution for new roof installation as well as re-roofing applications."

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 hold-out and six-month UV- resistance, also compared to roofing felt.

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.
