Interior of Basement Walls

There's a Dow insulation solution that's right for every Interior Basement Wall.

A better, and easier way to insulate your basement.

Turn your cold, damp, musty basement into a dry, comfortable, useable room – faster and easier. Forget time-consuming stud walls, multiple-vapor barriers, and cavity insulation that can absorb moisture. In a few simple steps, STYROFOAM™ WALLMATE™ extruded polystyrene slotted insulation creates a more energy-efficient and moisture-resistant basement than traditional methods. And because there is no framing required, you lose less floor space. It's lightweight, cuts cleanly with a score and a snap, so it installs easily, cleanly, and quickly.
