About this product
Cellofoam's POLY SHIELD heat laminated sheathing, offers tough poly facers for added strength and durability-important in storing, handling and installation. POLY SHIELD's closed cell expanded polystyrene (EPS) core wraps the structure in permanent R-value, retarding radiant heat flow and reducing air-infiltration. POLY SHIELD offers both high efficiency and low cost insulation. It is made of Cellofoam EPS rigid insulation, faced with a tough poly laminate or a reflective foil facer. If a reflective surface is Not desired, poly laminate can be ordered on both sides. Because POLY SHIELD is made of millions of closed cells of expanded polystyrene, it has an excellent resistance to heat transfer. Not a vapor barrier. When POLY SHIELD is properly installed it doesn't deteriorate with age, is resistant to mildew, rot, fungus, bacteria, and doesn't require maintenance. The tough facings resist abuse during construction and storage/warehousing. It is recyclable and environmentally friendly. It contains no CFCs, HFCs, HCFCs Or formaldehyde. Features: Delivers the most R-Value per $ Retains Thermal Properties (No Thermal Drift) High Resistance to Moisture Lightweight Easy to Install Installation labor reduced by approximately 60% Versatile-- Poly Laminate and Reflective Foil Facers
