Spray foam insulation you choose has a critical impact on your home’s thermal efficiency. It prevents heat from escaping in winter and keeps cool air in during summer, helping you save energy and lower your bills. Insulation also helps reduce moisture damage and mold, as well as improves indoor air quality by reducing the entry of outdoor pollutants.
The type of attic insulation you choose depends on the R-value recommended for your climate zone and how much you want to spend. The higher the R-value, the more effective the insulation.
How Proper Attic Insulation Can Drastically Cut Your Energy Bills
Fiberglass blankets or sheets are a popular DIY choice. They are easy to affix to unfinished attic spaces and typically cost between $0.50 and $2.30 per square foot for materials and $1.15 to $1.50 for labor. Blown-in fiberglass, cellulose and mineral wool insulation are also a common option. They are comprised of small fibers that are blown into attic spaces with special equipment. They are easy to install, but can settle over time and require occasional top-ups.
Cellulose insulation has one of the highest R-values, ranging from 3.2 to 3.8 per inch. It is tightly packed, which makes it better at filling gaps and voids than other types of insulation. It also helps seal air leaks, which are the leading cause of energy loss in homes. This makes it a great option for ENERGY STAR Home Upgrade participants, as it improves the effectiveness of heating and cooling systems and allows them to operate at a more efficient level.
