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 DuPont's world-class, high-quality insulation solutions you can trust to deliver sustainable, durable performance.

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 a conventional roof, the insulation lies under a protective membrane covering. Our conventional roof insulations and sealants provide long-term thermal performance and moisture resistance. Plus, the insulation often can be reused.
DuPont™ Styrofoam™ Brand Tapered XPS Insulation products provide a positive slope to improve roof drainage. Send us your drawings, and we’ll provide a custom quote for your design.
