Insulating your attic is one of the cheapest home energy upgrades you can do. It reduces the cost of heating in winter and cooling in summer and eliminates air leakage that can increase your utility bills.

Most homes have some attic insulation, but not enough to make a difference in their energy costs. A properly insulated attic can help you save up to $250 a year in heating and cooling costs.

The Environmental Benefits of Choosing Spray Foam for Attic Insulation

The type of attic insulation you choose can make a difference in your savings, too. Fiberglass batt and roll insulation is a popular choice that’s inexpensive and easily fits between attic joists and trusses in an existing home. It is fire-resistant and resists mold growth. It has an R-value of about 2.9-4.3 per inch.

When considering attic insulation options, consider R-value—a measure of how well a barrier or material resists the flow of heat. R-value recommendations vary by climate zone and building code, but a common recommendation is R-30.

Blown-in fiberglass or cellulose insulation is another option. It is a bit more expensive than other attic insulation options and is harder to install correctly. It is also a favorite snack for rodents, and it tends to retain moisture. It has a higher maximum R-value than other types of insulation but can lose its R-value over time. It is usually a better option for new construction.

Mineral wool insulation is another attic insulation option that’s both natural and fire-resistant. It has a high R-value of 3.5 to R-4 per inch and provides good thermal and acoustic insulation. It is available in rolls and batting, but it may be more difficult to work with than other attic insulation materials.
