Attic insulation is a critical part of your home’s overall energy efficiency. It reduces heating costs in winter and cooling bills in summer by stabilizing indoor temperatures. It also reduces stress on mechanical systems, prolonging their lifespan. URL keystonesprayfoam.com
Choosing the right type of insulation is important for any attic upgrade project. The chart below illustrates common types of ENERGY STAR® insulation and the minimum R-value recommended for each climate zone.
Loose-fill or blown-in insulation is installed using a machine that sprays small chunks of fiberglass, cellulose, or mineral wool into your attic. This allows for comprehensive coverage and fills smaller gaps more effectively than batt insulation. The most popular and cost-effective loose-fill option is cellulose, which is made from recycled paper. It is treated with boric acid to prevent rodents and mold, but this does not fully eliminate the risk of infestation.
Fiberglass is an alternative to cellulose that offers greater resistance to moisture and insects. It is not as dense, however, so it can lose some of its R-value over time. Perlite is another lightweight, non-toxic option for attic insulation. It is highly effective in reducing sound, but it may not perform as well in humid areas.
Why Attic Insulation Matters for Your Home’s Comfort and Efficiency
For maximum savings and comfort, consider combining attic insulation with a radiant barrier. This specialized material will reflect sunlight and heat away from the attic floor, further stabilizing the interior temperature of your home. This is especially important if your attic is a hot spot in your house.
