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.
Does turning newspaper into insulation require bleaching?

Cellulose insulation is one of the most difficult materials to work with if you need new wiring or alterations to the home. When a puncture is made in the cavity where the cellulose has been installed, the material just pours out of the hole.
Why does cellulose get wet?
Some cellulose insulation materials can absorb up to 130 percent water by weight. Cellulose can get wet due to condensation, lack of air seal, or leaks in the home. The material dries very slowly after it absorbs the water, which causes it to deteriorate and settle.

How is cellulose fed into an insulation blower?
Densely packed bales of cellulose are fed into the hopper of an insulation blower powered by an electric motor. Rotating teeth or prongs at the bottom of the hopper fluff up the cellulose.
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.
How is cellulose blown into the attic?
The cellulose is blown into the attic or walls through long, flexible tubes that run from the blower to an application nozzle. The cellulose is allowed to fill the cavities or blanket existing insulation. No pressure is placed on the cellulose; it is allowed to settle over time. Walls are patched up and painted over.
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. In this second type, moisture introduced into the spray helps the cellulose stick to the wall.
Where does cellulose come from?
Cellulose insulation technically can come from any cellular plant source, such as corncobs or sisal. But commercial cellulose insulations are generally derived from wood, and more specifically from paper: recycled newspapers, cardboard, office paper, and other common waste paper products.
