Attic insulation is available in a variety of materials, all with different R-values and installation methods. You’ll need to choose the right type for your home based on your local climate and your budget.

Cellulose, fiberglass batts and blown-in loose fiberglass are standard options for attic insulation. Cellulose is made from recycled newsprint treated with a fire retardant, and is the most popular option. Fiberglass insulation is made of thin, spun glass fibers that trap air to stop heat from escaping or entering your home. Blown-in loose fiberglass is usually a better choice because it has a higher R-value per inch than cellulose and doesn’t lose R-value over time.

Mineral wool is another natural, fire-resistant attic insulation option that provides thermal and sound insulation. It is typically available in rolls or in batts, and it’s also resistant to rodents. Mineral wool can be pricier than other types of insulation, but it has a high R-value and is a healthier choice than some synthetic options.

Spray foam insulation is another standard option for attic insulation. It can be installed by homeowners who have a good understanding of how to work safely in the attic and access to equipment like a large-capacity vac. Spray foam insulation, which comes in open- and closed-cell varieties, doesn’t require a vapor barrier and can be sprayed directly onto attic surfaces to form an airtight seal. Open-cell spray foam has a R-value of about 3.5 per inch, while closed-cell can reach up to 7.
