What Is The R-Value Of 12 Inches Of Insulation?

The R-value of 12 inches of blown insulation varies depending on the type of insulation, but some common estimates can be made for different types. For example, loose-fill cellulose has an approximate R-value of 3.6 per inch. Loose-fill fiberglass (or fiberglass) comes in at about 4.1 per inch. For both of these, the R-value estimates are based on an installation that is fairly tight to the home’s surface.

For batt insulation (batts are pre-cut and placed into a stud bay), the R-value again varies with the brand, but for one important reason—the gap between each piece of insulation affects its R-value. If the gap is sealed, or better yet, filled with blown insulation, both the R-value and the air-sealing qualities are increased. The U.S. Department of Energy recommends about 3 ½ inches of insulation to achieve an R-38 rating for your home.
