Insulating Interior Basement Walls

With batts and rolls from R-11 to R-21, it’s easy to add insulation to interior basement walls. EcoTouch® insulation with PureFiber® technology is a practical choice for basements and all around the house because it is easy to use and environmentally sustainable.

For best results, ensure foundation walls are sound and free of water problems. Caulk and seal the band joist, plumbing, electrical lines, and other penetrations. Place faced insulation between the studs with the vapor retarder facing the interior of the room. For the band joist, use unfaced cut-to-fit pieces of insulation and place them snugly into the space. Cover with an interior finish material, such as drywall, as soon as the insulation is in place.
