What is Cellulose Insulation?
Cellulose Insulation is made almost entirely of post-consumer recycled newsprint. The fiber is chemically treated with non-toxic compounds to resist fire, pests, and mold. The Cellulose Insulation Manufacturers Association (CIMA) claims that insulating a 1,500 ft house with cellulose will recycle as much newspaper as an individual will consume in over three dozen years. If all new homes were insulated with cellulose this would remove 3.2 million tons of newsprint from the nation’s landfills each year.
Blown cellulose can be installed in new or existing structures. It's popular in attic applications because you can blow unrestricted depths of fiber to achieve very high insulating values. One of the biggest advantages of using cellulose is its high level of thermal resistance. Because of its density, it has a higher rating than fiberglass insulation and outperforms many common insulation products. Its loose nature makes it easier to install into irregular spaces, creating a custom-fit monolithic seal over an entire area.
From both health and environmental perspectives, cellulose is considered a "green" product and its' more ecologically sound than competing products. It doesn't contain formaldehyde and unlike Fiberglass cancer warnings are not required on its labeling. Since there are no glass fibers, as with fiberglass insulation, cellulose does not cause itch.
