What is R-Value for Blow-in Insulation?
R-value is determined by a grading system used to check the Insulation’s effectiveness. The higher the R-Value, the more insulated the material is. Depending on the location of the blow-in insulation, it could require a different layer of material.
Below are the two R values for Blow-in Fiberglass and Cellulose:
fiberglass: R-value of 2.2 to 2.7 per inch.
Cellulose: R-value of 3.1 – 3.8 per inch
