About This Product
Cellofoam POLY SHIELD is a laminated foam insulation board made of premium expanded polystyrene (EPS) rigid insulation that meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. Our Reflective Laminated EPS Insulation is heat laminated on1-side with a printed polypropylene facer and on the other side with a metalized, reflective facer. Properly installed with a dead air space, the reflective facer can provide a significant R-value boost to POLY SHIELD's thermal performance. Designed for commercial, industrial, and residential applications, POLY SHIELD wraps the structure in permanent thermal protection, retaining heat flow and reducing air infiltration. POLY SHIELD Reflective continuous insulation is also approved for Water Resistant Barrier (WRB) rated assemblies when all seams are taped, eliminating the cost, installation time, and need for a house wrap and vapor barrier. POLY SHIELD continuous insulation complies with the model building codes when properly installed as identified in Cellofoam's UL Evaluation Report ER7260.
Highlights
- Cost savings: EPS reduces energy costs and offers the highest R-value per dollar of any foam insulation board
- Premium quality: the EPS core meets or exceeds ASTM C578 specs, with excellent dimensional stability and compressive strength when properly installed it does not deteriorate with age, and is resistant to mildew, rot, fungus, and bacteria
- Stable R-value: the R-value of EPS is permanent because the only gas in EPS is air unlike Polyiso or XPS whose blowing agents outgas and therefore lose R-value, EPS R-values do not degrade over decades of use
- Easy to install: lightweight and can be cut to size
- Environmentally friendly: cellofoam EPS contains no formaldehyde or ozone-depleting CFCs or HCFCs the POLY SHIELD EPS core is 100% recyclable and may contain recycled material
- Moisture resistant: cellofoam EPS is quick drying and does not readily absorb moisture from the air its closed-cell structure reduces the absorption and migration of moisture, and the facers surfaces are nearly impervious to moisture not a vapor barrier
- Code approvals: meets or exceeds ASTM C578 underwriters laboratory listed, UL ER7260, for interior and exterior walls please consult local building codes for system requirements

Poly Shield Fan-Fold .5 in. x 48 in. x 50 ft. Rigid Foam Board Laminated EPS Insulated Sheathing R-1.93
Cellofoam POLY SHIELD Fan-Fold is laminated EPS insulation and underlayment that reduces application labor costs while adding R-value exterior walls as an insulative backer board for siding, but also can be used to insulate interior or basement walls. Each bundle is folded accordion style for easy transport and can be unfolded to cover a 4 x 50 ft. area. The accordion design allows for quicker installation than competing 48 in. x 8 ft. insulation or backer boards, saving time and money. Our Reflective Laminated EPS Insulation is heat laminated on one side with a printed polypropylene facer and on the other side with a metalized, reflective facer - when properly installed with a dead air space, the reflective facer can provide a significant R-value boost to POLY SHIELD's thermal performance.
