Home Comfort and Energy Efficiency

Residential basement insulation is material added to a basement's walls, floors, or ceiling to reduce moisture buildup, improve energy efficiency, and help regulate indoor home temperature. Because basements are a common source of heat loss, properly insulating them is an integral part of a whole-home residential insulation strategy. Installing basement insulation can contribute to a more comfortable living space, reduce heating and cooling demands, and help limit issues like dampness or drafts. Whether part of a finished living space or an unfinished utility area, crawlspace and basement insulation supports long-term comfort and energy performance.

              More About Owens Corning Basements & Crawlspaces Products

              There are many benefits to proper basement insulation, from helping to prevent cold drafts and condensation to reducing energy costs. This insulation is especially important because basements and crawlspaces are often significant sources of heat loss and moisture in a home. Basement wall insulation helps keep heat from escaping into the ground, especially in unfinished or partly finished spaces where the walls and floors are exposed to cooler conditions. Basement ceiling insulation can help block sound between floors and separate heated areas from unheated ones, assisting with whole-home noise control and energy efficiency. Factors like regional climate zone, soil type, and area moisture levels all play a role in determining the proper insulation approach. Whether it’s a new build or a retrofit project, choosing the right insulation material depends on these conditions and how the space is used.

              Owens Corning offers a range of insulation materials that can be suitable for residential basement and crawlspace applications. Fiberglass insulation is available in flexible formats for framed basement walls, ceilings, and smaller areas. These basement insulation products also help manage heat and sound. Mineral wool insulation also provides sound control and added fire resistance, making it a good fit for finished basement walls or retrofit applications where cavity insulation is needed. XPS rigid foam board insulation is ideal for interior and exterior basement foundation walls and under slab use, thanks to its consistent thermal performance, resistance to moisture, and availability in options that help manage drainage along foundation walls. For rim joists and crawlspace applications, spray foam insulation can help fill gaps, limit air movement, and is compatible with both vented and garage wall insulation needs.
