Start off on the Right Foot

For the exterior foundation, Dow provides residential builders and homeowners with energy-saving solutions from footer to sill plate.

Concrete is a poor insulator. In addition to energy loss, uninsulated exterior walls can result in condensation on these cool basement wall surfaces. As a result, it's smart to insulate the exterior foundation to save energy, keep basement walls warm and reduce the potential for moisture problems.

Insulation products from Dow feature high compressive strength, long-term thermal performance and exceptional moisture resistance – making them ideal for exterior foundations.
