Cellulose insulation is a favorite of the green home building movement. Insulation is a recycled insulation which makes it a very popular material to insulate buildings. It is made from newspaper which is always in ample supply. There are several different ways that the newspaper is processed.
Why is newspaper insulation favored?
This process is the favored process because you get a much denser material. Once the newspaper has been reduced to fibers a mold inhibiting chemical and a fire retardant chemical is mixed with the fibers. In some cases dry binders are mixed in. The newly formed insulation is bagged up and shipped to building suppliers.

What is the best insulation for a wall?
There are a number of advantages to using cellulose insulation over other types: 1 Loose-fill cellulose insulation can settle around and conform to most of the obstructions found in walls and attics. 2 Loose-fill cellulose is relatively inexpensive, yet still has an R-value of about 3.5 per inch of thickness, compared to fiberglass' R-value between R3 to R4 per inch. 3 When walls are already finished, injecting loose-fill cellulose insulation is one of the few ways of adding insulation. One alternative is to pull down the drywall and use fiberglass batts. 4 Cellulose insulation stands up reasonably well against insects and vermin because it is treated with borates.
Why is settling in attics bad?
Settling in attics is less problematic for two reasons. First, attic spaces can be overfilled to account for settling. Second, when cellulose insulation in attics settles, no empty spaces are formed. When cellulose soaks up moisture in enclosed areas, it can take a long time to dry out.
What is loose fill insulation?
The most common type that homeowners will encounter is called loose-fill cellulose insulation . This is slightly different from another type of cellulose insulation, which is designed to be blown onto open walls, much like spray foam.

For attics, the joists are often open and accessible and thus could be insulated with either blow-in cellulose or fiberglass batts. However, because of obstructions such as wires (and just because of its sheer ease), cellulose insulation is often blown into attics, as well.
What is cellulose insulation?
Electrical short circuits and heat producing devices were almost always the cause, igniting the cellulose material and causing home fires. The potential burning hazards of cellulose insulation soon caught on and government agencies passed stringent regulations on their safety in the 1970s.
