Attic insulation is a vital component of home energy efficiency. It reduces energy bills, increases thermal comfort, and enhances indoor air quality. But the type of attic insulation you choose depends on your location and other priorities, and there are a variety of installation methods.
The Department of Energy recommends insulating your attic to a certain R-value, and different climate zones have different R-value requirements. For instance, in balmy South Florida, one layer of R-30 fiberglass batting should be enough for most homes. On the other hand, residents of wintry Wisconsin should add at least two layers to achieve the recommended R-value.
Choosing the Right Attic Insulation for Your Home
Fiberglass batt insulation, also known as blanket insulation, comes in rolls or sheets that resemble thick blankets. It’s inexpensive, easy to install, and offers good thermal resistance. It’s a common choice for attics, and it’s available in a range of R-values from R-30 to R-60.
Blown-in fiberglass insulation is another economical option. It’s blown into the attic with a machine that fills spaces and gaps with ease. It’s also ecofriendly and made from recycled newspaper and cardboard.
Spray foam insulation is more expensive than other attic insulation options, but it provides superior performance and creates an airtight seal to prevent drafts. It’s especially effective for complex attic shapes and helps improve thermal efficiency, soundproofing, and indoor air quality.
As you shop for a contractor to perform attic insulation, get several quotes and check references. You should also find out whether the company is licensed in your state. If not, you could be liable for any damage or injury they cause.
