Outside, inside or in systems, you have the option to choose a proven energy-saving insulation for your application.
Even though you may insulate the frame walls, ceilings and attics of your home, the fact is when foundations are left bare uninsulated - they can account for 22% of total house heat loss.
The reason is the R-value of bare foundations is not much higher than glass. A single pane of glass has an R-value of 0.86. a full foot of concrete has an R-value of 1.0. So rather than building homes on "glass" foundations, builders use and rely on STYROFOAM brand insulation. It's the one insulation that dramatically reduces heat loss and with it, ensures home buyers exceptional energy saving regardless of what type of foundations you build into your home.
The unique physical properties and resultant thermal efficiencies of STYROFOAM have set performance records unmatched by any other rigid foam insulation.
Exceptional Moisture Resistance. The polystyrene resin and extrusion process used to produce STYROFOAM brand insulation creates a closed cell structure. Since there are no voids or gaps between the cells, the rigid boards resist all forms of water penetration. This exceptional water resistance ensures reliable thermal efficiencies over the life of your homes.
High Compressive Strength. The unmatched compressive, crush-resistant strength of STYROFOAM stands up against handling backfilling or imposed loads after installation. Broken or crushed below-grade insulation won't deliver thermal efficiencies. STYROFOAM will. Year after Year.
Long-Term R-value. Since the 1940's, STYROFOAM brand insulation has a track record of long-term R-Value retention second to none. Proven dependability, long-term R-value retention second to none. Proven dependability, long-term R-value retention second to none. Proven dependability, long-term R-value that's what separates STYROFOAM brand insulation from the rest. That's been proven in tests and thousands of below-grade installations.

18-Month Moisture Resistance Test. Three rigid insulation products were installed along the exterior foundation walls of a building. At the end of 18 months, STYROFOAM brand insulation had retained 96% of its original R-value; molded bead polystyrene retained 75%, and aluminum foil-faced polisocyanurate, 60%.
Insulating basement walls inside and out will pay off for years. Uninsulated basement walls can be the greatest source of heat loss in a home. Use STYROFOAM brand Tongue & Groove insulation on the exterior walls and that heat loss can be reduced by up to 75%. Year in, year out.
Insulate the interior walls with easy-to-install STYROFOAM WALLMATE to provide a thermal envelope that helps save energy while converting basements into comfortable living spaces. The rigid boards are installed directly on the masonry wall. Wood nailing strips secure the insulation and the drywall to the basement wall. No extensive framing or vapor retarders are needed, saving you time and money.
And since STYROFOAM WALLMATE is highly moisture resistant, incidental basement leaks and moisture have virtually no effect on its insulation value. It performs for years.
Homeowners save money by insulating crawl space walls. In a typical crawl space wall application, STYROFOAM brand insulation can save you an average $250 per home in materials and labor. Here's how: crawl space wall areas are much smaller than floor areas; therefore you use less materials. In fact, 1" of STYROFOAM brand insulation on crawl space walls provides energy performance equal to 6 ½" batts in the floor. And you save time and labor. STYROFOAM brand insulation is installed before the floor. Builders can work standing up and the crawl space joist areas remain clear for wiring, plumbing and ducting access. During the heating season, STYROFAOM brand insulation locks heat into the crawl space, keeping it warm and dry. In the cooling season, STYROFOAM blocks out heat and humidity. Crawl spaces remain cool.
Slab-on-grade insulation reduces heat flow and energy costs. When used for monolithic or supported slab on grade, STYROFOAM brand insulation reduces foundation heat flow. Floors retain warmth in the heating season and stay cooler during the cooling season. And having superior moisture resistance, STYROFOAM brand insulation withstands years of exposure to wet earth and freeze-thaw cycling.
