Description

PolyPro™ sheathing for exterior wall applications is a rigid insulation consisting of high-performance closed cell Expanded Polystyrene (EPS). Our insulation is available with factory laminated metallic reflective facer, clear facer on the back. Our laminates are micro-perforated to reduce moisture buildup in the wall. PolyPro™ has a stable R-Value that will not decrease over the life of the product. PolyPro™ insulation does not contain any ozone depleting HCFCs or formaldehyde, and the foam core is 100-percent recyclable. As an added bonus, PolyPro™ will not promote the growth of mold or mildew.
