EPS Polyshield


EPSPOLY SHIELD heat laminated sheathing, offers tough poly facers for added strength and durability-important in storing, handling and installation.

POLY SHIELD’s closed cell 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.

POLY SHIELD is made of Cellofoam Expanded Polystyrene (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. Standard thicknesses are 1/2″, 3/4″ and 1″. Standard density is 1#. Other densities are up to 3# pcf and thickness up to 4″ are also available.

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.

Thermal Retention
All types of EPS insulation will retain their specified thermal and mechanical properties even after being subiected to in-situ freeze-thaw cycling.
