Insulating Exterior Foundation Walls

Concrete walls have low insulating value, which means cold from the ground transfers directly into the basement. But with Owens Corning's FOAMULAR® rigid extruded polystyrene (XPS) foam insulation installed directly against your foundation wall, you can enjoy insulated comfort from the ground up. With its excellent moisture resistance and rugged construction, it won't lose any insulating power—even after long-term exposure to water or decaying elements in the soil.
