Cellulose is onlyBatt Fiberglass Insulation available as blown-in insulation. Both materials are suitable for insulating your home, and their R-values are approximately equivalent.

More commonly used, many can recognize fiberglass insulation as the “pink fluffy stuff.” Fiberglass does not rot or decay. The fiberglass itself won’t catch fire, but it will melt in cases of extreme heat. The paper backing on batted fiberglass insulation is the only part that is flammable. Additionally, fiberglass loses as much as 50% of its R-value when temperatures drop below 20 degrees Fahrenheit.


Cellulose Insulation

Cellulose is made from paper, sometimes even recycled newspaper. Treated to be flame-retardant, the paper has only caught fire in very extreme cases. The paper isCellulose Insulation also treated to help prevent rot and decay, but these issues are still a possibility if there is prolonged moisture exposure. Additionally, made up of a minimum of 85% recycled material, cellulose insulation is considered more environmentally friendly than fiberglass. Plus, in extreme cold, cellulose doesn’t lose any R-value, making it a better insulator in cold climates.
