Home Comfort and Energy Efficiency

Proper attic insulation is essential for improving home comfort and energy efficiency. Without adequate home attic insulation, residences can lose heat in the winter and gain excess warmth in the summer, which can result in inconsistent temperatures and higher energy bills. For many homes, an uninsulated or poorly insulated attic can be one of the biggest sources of energy loss. Owens Corning offers a variety of residential attic insulation products, including fiberglass batts, blown-in insulation, and spray foam solutions. These insulation products are available in a range of R-values to meet various climate zone requirements and support optimal energy efficiency. These residential insulation products help reduce heat loss, manage moisture, and maintain consistent indoor temperatures.

                More About Owens Corning Residential Attics Products

                Attic insulation can positively impact homes, budgets, and the environment. It helps regulate home temperatures and supports energy efficiency. Proper installation of insulation also improves indoor comfort and air quality while helping manage moisture, reducing the risk of mold and structural damage. Insulating the attic can lessen the strain on heating and cooling systems, which may extend HVAC lifespan and improve overall efficiency. According to the EPA (Environmental Protection Agency), homeowners can save significantly on heating and cooling costs by properly air sealing and adding insulation in key areas like attics, floors over crawl spaces, and basements. Adding insulation to these areas can improve energy efficiency, reduce costs, and support better indoor comfort.

                Owens Corning’s fiberglass attic insulation is available in batts and blown-in options, making it well-suited for various attic spaces. Blown-in fiberglass insulation is ideal for helping to fill gaps and hard-to-reach areas, while fiberglass batts offer precise coverage for open spaces and between joists. Both types of fiberglass insulation options help provide thermal performance and sound control.
