Our Reflective Laminated EPS Insulation is heat laminated on 1-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.
