The Duro-Tuff® PVC roof membrane is a proprietary thermoplastic formulation that provides a highly reflective, durable, and superior quality product. An 18 x 9 weft-inserted anti-wicking knit scrim that is laminated between two layers of PVC film gives the membrane its strength and durability. This EPD applies to the Duro-Tuff® single-ply membrane in white, light gray, charcoal, light tan, patina, copper, blue, and green, 50-mil, 60-mil, and 80-mil nominal thicknesses. The Duro-Tuff® membrane was engineered to be used with the complete line of Duro-Last’s proven, precision-fabricated flashings for curbs, stacks, and parapets. Duro-Tuff® can be applied by a Duro-Last certified contractor utilizing a variety of methods, including mechanically fastened, Duro-Bond® induction welding, or fully adhered. All commercial warranted installations are inspected by Duro-Last’s certified Quality Assurance Technical Representatives
