Styrofoam™ Brand XPS Insulation vs. EPS
Water can cause damage in freeze-thaw conditions. XPS insulation absorbs significantly less water than EPS products do. And, it maintains its R-value better when water is present. Styrofoam™ Brand XPS also has recycle/reuse ability. All of which improve performance, sustainability and life-cycle cost.
Enable next-generation roofing solutions with science-based materials that deliver the performance needed for sustainable, durable construction.
Simplify installation with durable insulation, sealing and adhesive solutions from DuPont Performance Building Solutions.
In a protected membrane – or inverted – roof, the insulation is placed on top of the waterproofing membrane and covered with gravel, pavers or soil. PMR roofs are ideal for green and blue roof designs. They lengthen roof life, contribute to sustainability and provide long-term cost savings.
In the U.S., a 50-year thermal limited warranty is available from DuPont on Styrofoam™ Brand Insulation products 1.5 inches and greater.
Styrofoam™ Brand Deckmate™ Insulation products 1.5 inches and greater are eligible for a limited 50-year reuse warranty when used in conventional roofing applications. For thickness less than 1.5 inches, other warranties may apply.
