EPD: PVC waterproofing roof membrane, single-ply, 50 mil, 0.28 lb/ft2, Duro-Last EV® 50-mil (DuroLast)
The Duro-Last® EV 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 laminated between two layers of PVC film gives the membrane its strength and durability. Duro- Last EV contains Elvaloy® KEE (Ketone Ethylene Ester), a polymer manufactured by DuPont™ that provides non-migrating flexibility in roofing membranes. This molecule may replace plasticizers in roofing products, and when mixed with PVC, provides resistance to chemical attack, weather resistance, long-term flexibility, durability, and resistance to microbial growth. This EPD applies to the white Duro-Last EV single-ply membrane in 50-mil and 60-mil nominal thicknesses. The Duro-Last EV membrane was engineered to be used with the complete line of Duro-Last EV precision-fabricated flashings for curbs, stacks, and parapets. Duro-Last EV can be applied by a Duro-Last certified contractor using various methods, including mechanically fastened, Duro-Bond® induction welding, or fully adhered. Nearly all Duro-Last EV membrane installations are inspected by Duro-Last’s certified Quality Assurance Technical Representatives
