How much insulation should I add to my attic? Follow

The recommended level for most attics is to insulate to R-38 (or about 12 -15 inches, depending on the insulation type). In Northern climates, as much as R-49 is recommended. R-Value is a measure of the insulation's ability to resist heat flow. The higher the R-Value, the better the thermal performance. Visit ENERGY STAR Home Sealing for more information, including recommendations for how much insulation you should have.
