Attic Insulation – What Type of Attic Insulation is Best?
Attic insulation is the most cost-effective way to trim your energy bills. Having a fresh layer of attic insulation also helps reduce moisture in the house, prevent rodent infestation, and keep you warm and cozy all year round.
The best attic insulation type depends on your climate, budget, and home energy efficiency goals. ENERGY STAR recommends you use attic insulation that meets or exceeds the Department of Energy’s recommended R-value for your region. You can choose from loose-fill, fiberglass batts, blown-in cellulose, and spray foam insulation.
Attic Insulation Installation: What to Expect from the Process
Fiberglass batt insulation is made of recycled sand and glass, making it eco-friendly. It is very effective at insulating against heat and cold and is available in varying R-values to suit your needs. It comes in rolls which make it easier to install, and it can be cut to length if needed.
Cellulose insulation is made of recycled, ground-up paper that has boric acid added for insect control and fire resistance. It is a greener option than fiberglass and has an R-value of 3.2 to 3.7 per inch.
Mineral wool is another natural attic insulation choice that is similar to cellulose. It is resistant to mold and mildew, and it can retain its R-value even if wet.
Closed-cell foam is an alternative to cellulose and fiberglass insulation. It is three times as dense and more expensive than fiberglass but has a higher R-value. It can be hard to work with due to its rigidity but it does offer a good solution for sealing recessed light fixtures, electrical boxes and pipes in the attic.
