DuPont has launched a roofing underlayment product line — the Tyvek® Protec™ PSU peel and stick underlayment. The new product is designed to provide high-performance, high-temperature, and UV resistance along with a slip-resistant walking surface. Features include a split liner for easy installation, ICC-ES code report, and FL/Miami-Dade certification. The product debuted at the International Builders show February 27, with full commercial scale up taking place later in 2024.

The self-adhered Tyvek Protec PSU product is specifically intended for critical areas of the roof, such as the eaves and valleys, that are more susceptible to water leaks. The adhesive layer, composed of rubberized asphalt, serves as an additional sealant, offering superior protection at fasteners and nails compared to a mechanically attached sheet. The product also functions as a shield against water intrusion due to wind-driven rain and ice dams, allowing it to cater to different climates and regions.

"Tyvek Protec PSU completes DuPont’s portfolio of roof underlayment products, allowing for a single supplier for both mechanically attached underlayment and PSU," said Victoria Raineri, residential marketing manager for DuPont. "This ensures brand continuity, making it easier to address codes with products from one cohesive portfolio."
