The proper type of insulation depends on a variety of factors, such as the location of the project, and the setup of the existing structure. When it comes to attics, the three main forms of insulation used are: spray foam, fiberglass, and cellulose. Spray foam is open cell, and it is considered to be an environmentally friendly product. Fiberglass is an affordable option that many homeowners can install themselves. Cellulose is also inexpensive and easy to install, but it can end up settling up to 20% overtime.

- When installing attic insulation, your options are fiberglass, open cell spray foam, or cellulose.
- While fiberglass is less expensive, spray foam is a better option because it forms an air seal and does not retain water.
“High energy bills and the inability to maintain a constant temperature are just some of the signs your attic needs new or updated insulation. The best insulation options for an attic are open cell spray foam, fiberglass, and cellulose.”
