About DuroSpan® GPS

DuroSpan® GPS is manufactured using a graphite- enhanced expandable polystyrene (GPS) insulation with a thin film laminated to the top and bottom surfaces. The DuroSpan GPS products provide continuous insulation required by energy codes.

Available in thicknesses to meet R5, R7.5 and R10, the DuroSpan GPS insulation is more durable and provides reduced heat loss, enhanced thermal resistance, and improved interior wall temperatures for a more energy-efficient structure.

DuroSpan GPS insulation is a GreenGuard Gold certified product. Sustainable in both product and manufacturing, DuroSpan GPS is free of HCFCs, improves indoor air quality, and does not degrade over time.
