A typical R30 fiberglass insulation is 10 inches thick. In temperate coastal areas such as zone 3, a minimum roof insulation of R30 to a maximum of R60 is recommended. For loose cellulose, this translates to an overall depth in the range of 8 inches to 16 inches.
What is the R-value of 4 inches of cellulose insulation?
Cellulose is not uncommon in this regard. Like many insulating materials, it offers an R-value of about R3.5 per inch of thickness. However, air leakage through cracks, voids and gaps is significant and accounts for about a third of a home’s average heat loss.
What is the R-value of 6 inches of cellulose?
Moisture sprayed loose filled cellulose insulation has an R-value of up to 3.7 per inch and also has excellent water repellency. A 6-inch wall void insulated with loose-fill cellulose should achieve an overall R-value of 22.
