Types of Attic Insulation

When installed properly, spray foam insulation reduces energy costs and makes a home more comfortable year-round. It prevents warm air from escaping through the roof in winter, and it blocks heat from radiating down into living spaces during summer. A well-done attic insulation project also helps improve indoor air quality and can reduce noise transmission.

Before adding new house insulation, a roofer should inspect your attic space to assess its condition. He or she should look for roof problems and rafter damage, which he or she may repair before installing the insulation. Your roofer can also advise on the type of attic insulation that would work best in your climate.

Fiberglass batts are the most common choice for attic insulation. They are cheap, easy to install and offer good thermal performance. They are available with a variety of R-values that meet your needs, from about R-30 to R-60 depending on your region.

Loose-fill insulation is another option. This is usually made of recycled paper or wood products, such as cellulose. It is blown into the attic cavity by hand or with a machine. It provides a higher R-value per inch of thickness than fiberglass batts, and it is more flexible to fill gaps and hard-to-reach spots than other types of insulation. It is typically treated with the mineral borate to improve fire and insect resistance.

Spray foam is another insulation option, especially if you have an open attic space with no existing batting or vapor barriers. It is a liquid-applied foam that expands to fill wall cavities and create tight seals around pipes and wiring. It offers the highest R-value for an inch of thickness, and it can be used in attics as well as wall cavities. It is also highly durable, and it resists mold growth and odors.
