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.
What Is Loose-Fill Cellulose Insulation?
Cellulose insulation is thick, dense, and clumpy, with a consistency much like down feathers. The chief value of this shape and size is that the insulation can fit in enclosed areas (such as walls) and can conform around obstructions such as wires and ducts (found both in walls and in attics).
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.
