Cellulose (not to be confused with cellulite, which would be nasty to leave in your attic) is one of the most popular products in the insulation industry. It is made of old newspapers, reducing landfill waste and making this type of insulation one of the most environmentally-friendly options out there. cellulite: the image shows cellulite in a pile on a wood floor.

Let's run down the list and point out some of the facts concerning cellulose insulation.

  • The two most popular kinds of cellulose insulation are dry, which is a loose fill install, and spray-applied, which is a wet spray install.
  • Cellulose insulation shows the same, if not slightly better, thermal performance as rock wool insulation.
  • This kind of insulation fits extremely well around pipes and wires, and can constrict a building up to 30% more tightly than other types of insulation.
  • While some forms of insulation require a separate vapor barrier, it is recommended in most cases that no vapor barrier be installed when using cellulose installation. Exceptions to this rule include places with higher than normal moisture levels or areas where it is very cold.
  • When properly installed, this stuff leaves few air pockets to disrupt the building envelope.
  • Cellulose insulation has excellent sound absorption qualities, ranking only slightly lower than rock wool insulation.
  • During the manufacturing process, this insulation material is chemically treated with borates, improving fire retardation properties and inhibiting the growth of mold.
  • It also diffuses moisture within areas such as attics, allowing the space to dry quickly.

Installing cellulose insulation is not a task recommended for do-it-yourselfers. It is a job for professionals, using professional equipment. For example, have you seen the Capitol Machine International Model 100? This sucker can blow R-30 grade insulation into a 2000 square foot house in around 45 minutes. Now that’s power!
