Types of Attic Insulation

Insulating your attic is one of the most cost-effective and energy efficient home upgrades you can do. It improves your home’s comfort, reduces energy costs, protects the roof and structural members from moisture, and can help to lower airborne pollutants that can cause respiratory issues.

There are several different types of spray foam insulation that can be used in attics. While some can be installed by homeowners, others require a professional installer to ensure the installation is completed correctly. This is especially important when working with materials such as spray foam and rigid foam boards.

Fiberglass batts are the most common type of insulation for attics and can be purchased for relatively low cost. They provide a high R-value per inch and are easy to install. However, they can absorb moisture and lose their R-value over time. This can result in mold and mildew growth. Additionally, they may off-gas during and after installation, requiring adequate ventilation.

Cellulose insulation is made from recycled paper and has an R-value of 3.2 to 3.7 per inch. It’s considered an eco-friendly option and can be treated with a fire retardant additive such as ammonium sulfate or borate, increasing its safety. However, it does not have the same moisture resistance as fiberglass and can retain water, reducing its R-value over time.

Mineral wool is another insulation material that can be blown or tucked into attic spaces. It’s a great choice for homeowners who want to tackle the project themselves as it can be done by hand without the need for a power tool. It’s also resistant to moisture and can retain its R-value over time.
