Expanded Polystyrene (EPS) Exterior Wall Insulation

The reason EPS is such a good insulating material is the millions of air pockets which are formed when the blocks are molded. These pockets impede the flow of heat, making EPS an excellent insulator -- keeping things cool in the summer and warm in the winter. High quality EPS wall insulation is available in a variety of sizes.

Sheets of EPS are used to insulate the inside or outside of foundations. The material can come into direct contact with the earth without any degradation over time. Sheets can be installed on the outside of wall framing or between the studs as is currently being done in areas where flooding has become routine. Unlike fiberglass insulation, EPS absorbs very little moisture and as soon as the source is removed will dry out completely and quickly.

Panels are available in thicknesses from 3/8" and up. They are available un-faced or laminated with 1-mil polyethylene film or metalized poly reflective film depending upon the application.
