R-Value is a measure of insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
What are the disadvantages of cellulose insulation?
Disadvantages. Installation costs for cellulose can be higher than for fiberglass. Cellulose insulation creates an enormous amount of dust when it is installed, so a certified breathing mask is absolutely essential. Dry-blown cellulose sags and settles, reducing its R-value over time.

What kind of insulation is used in Attic?
Blown-in insulation, also known as loose-fill insulation, is ideal for attic insulation, basement insulation and ceiling insulation. There are two main types of blown-in insulation: cellulose and fiberglass. Cellulose insulation is made from recycled paper that’s treated for fire resistance and packs tightly between joists.
