What is Blown Cellulose Insulation?

Blown cellulose insulation is made from recycled paper products, such as newspapers and cardboard, that are treated with fire-retardant chemicals. The treated paper is then shredded and blown into the walls, attic, or crawl spaces of a home to provide insulation against heat loss.

Blown cellulose insulation has several benefits, including:

  • It’s an eco-friendly option since it’s made from recycled materials.
  • It’s a cost-effective option since it’s cheaper than other types of insulation.
  • It’s a great option for hard-to-reach areas, such as attics and crawl spaces.
  • It’s an effective option for reducing air leakage and heat loss.
