Building Insulation Products Laminated EPS Insulation

Poly Shield® XR

  • Expanded polystyrene (EPS) insulation core with white woven facer on one side and reflective facer on the other
  • White woven facer exposed on the inside of building is durable and washable; no additional interior protective layer required
  • High R-value rigid insulation, saves energy costs and brightens building interior
  • Available in 4x8, 4x9 and 4x10 foot sheets, 1/2 to 6 inches thick
  • Not for commercial or residential use


Superior R-Value, strength, & brightness in a washable interior insulated sheathing for Warehouses & Agricultural Buildings. Please consult local building codes for system requirements. We recommend regular Poly Shield® instead of Poly Shield® XR for residential or inhabited commercial buildings.


Cost Savings

EPS reduces energy costs and offers the highest R-value per dollar of any foam insulation board. Poly Shield® XR is lightweight and easy to install.

High, 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. When combined in a wall design facing dead air space, our reflective metalized facer increases R-value significantly.

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. When properly installed it does not deteriorate with age, and is resistant to mildew, rot, fungus, and bacteria. Not a vapor barrier.

Premium Quality

The EPS core of Poly Shield® XR meets or exceeds ASTM C578 specs, with excellent dimensional stability & compressive strength. Our white woven polymeric facer is our highest quality and most durable facer.

Environmentally Friendly

Cellofoam EPS contains no formaldehyde or ozone-depleting CFCs or HCFCs. Poly Shield's EPS core is 100% recyclable and may contain recycled material.

Manufactured to your Needs

Poly Shield® XR sheathing is available in 4 ft wide boards in lengths from 8 to 20 ft, in thicknesses from 1/2 to 6 inches, and in ASTM C578 nominal densities of 1.0, 1.25, 1.5, and 2.0 lb/ft3.
