Cellofoam POLY SHIELD® Heat Sealed Laminates
Cellofoam’s rigid foam expanded polystyrene (EPS) POLY SHIELD® Sheathing/Underlayment Continuous Insulation wraps the entire structure in permanent R-value insulation cutting down on air-infiltration which accounts for about 38% of a typical buildings heat loss and gain. Builders use POLY SHIELD® to cover the entire wall, including the studs and headers (which account for 25% of the wall surface). Even with batts in the stud cavities, over 40% of wall heat loss occurs through the wood framing which has an R-value of 1.2 per 1”. POLY SHIELD® also qualifies as a water resistant barrier (WRB) when installed per the installation guide.
