Attic Insulation Thickness Guide
Insulation is one of the fiberglass insulation and most cost-effective ways to improve your home’s energy efficiency and comfort. The U.S. Department of Energy recommends attic insulation with an R-value of between R-38 and R-49. This typically corresponds to a thickness of between 13 and 17 inches, depending on the insulation material used.
Different insulation materials offer unique benefits and drawbacks, and each has a distinct impact on your home’s performance. It is important to understand the recommended R-values and optimal thicknesses for your climate zone, as well as the differences between blown in and rolled fiberglass batt insulation, to ensure you achieve maximum energy savings.
When to Replace Insulation: Key Signs Homeowners Shouldn’t Ignore
A properly insulated attic prevents heat loss during the winter, reduces cooling costs in the summer, and provides a sound barrier to keep out critters such as mice, raccoons and squirrels. It also helps maintain consistent indoor temperatures and decreases humidity levels, which protects your home from mold and mildew.
Choosing the right type of insulation can help you recoup your investment within 3 to 5 years through energy savings. There are a few factors to consider when calculating the cost of attic insulation, including area size, labor rates, and the availability and cost of materials. For example, insulated wall cavities and difficult to reach attic access points can require additional labor to properly air seal and then insulate, which may increase installation costs.
Depending on your needs and home insulation goals, there are a variety of professional and DIY options to choose from. For example, a professional installation using a combination of attic insulation, foam board and spray foam will have a higher upfront cost than a DIY project with rolled fiberglass batts. However, many homeowners recoup the initial investment through energy savings over time.
