Homeowners who install new attic insulation as part of an ENERGY STAR® Home Upgrade can improve energy efficiency and comfort by sealing air leaks and choosing the right insulation material. To make the best choice, consider your regional climate, current attic insulation level, and budget.
Fiberglass batt insulation is a standard option for many homes and is based on recycled glass, sand and other materials. It is available in a variety of R-values and fits between studs and joists to provide thermal insulation. It is also soundproof, helping to reduce outside noise and internal noise. It can be installed with a vapor barrier to help control moisture and protect against mold.
Choosing the Right Attic Insulation Material
Commercial insulation is another standard attic insulation choice. It is sprayed in place to fill spaces between joists and studs, ensuring an airtight seal that helps reduce energy waste and improve attic ventilation. It is available in open- and closed-cell options to meet different needs and budgets. Closed-cell spray foam is denser and more expensive but offers better moisture resistance and strength.
Natural insulation like hemp and cellulose is also a good option, especially for eco-conscious homeowners. It is hygroscopic, meaning it can absorb and release moisture to maintain a stable R-value. It also provides excellent soundproofing and is fire-resistant. Since it does not use chemicals, it is also safer for sensitive people than synthetic alternatives. However, it is important to note that cellulose can be susceptible to mold growth if water gets into the insulation. This can be avoided by installing a vapor barrier in the attic to prevent moisture from reaching the cellulose and creating a moist environment.
