Cellulose – Better

Modern cellulose insulation is made mostly from recycled paper and denim. The other percentage of content is a fire retardant such as boric acid or ammonium sulphate. It can be either a loose-fill or blown-in insulation and can be used in both new and existing homes. You can use cellulose in enclosed existing walls, open new walls and unfinished attic floors.

The Positives:

  • Made with mostly recycled material
  • Does fill small voids and openings
  • Inexpensive
  • The use of boric acid makes it resistant to mold, pests and fire.

The Negatives:

  • Tends to poorly protect against air flow which contributes to energy loss
  • Settles up to 20% which negatively impacts the energy in your home
  • Must be kept dry and free of moisture
  • As it loses its overall effectiveness over time it begins to create more dust and particulate matter throughout your home.
  • It weighs more than fiberglass which makes it tough to use in attic spaces and slopes.
