How Deep Should Blown-In Insulation Be in Your Attic?

Jun 28, 2021

How Thick Should Blown-In Insulation Be Blown-in attic insulation is a proven solution for improving the energy efficiency of the home. But the efficacy of the insulation depends on its R value and how thick it is layered in the attic. R value indicates how well the insulation can stop heat transfer—the higher the R value, the better the thermal performance. If you own a home in Texas, where the weather can get quite hot, it’s worth investing in attic insulation that has a high R value to ensure your HVAC has an easier time of cooling your home.

Measuring Thickness of Attic Insulation

The R value of the blown-in attic insulation will determine how thick it needs to be installed in the attic. Fiberglass insulation has an assigned R value per inch. Dividing the overall desired R value by the per-inch figure will give you the ideal thickness to ensure optimal performance. Most times, it is 10 to 14 inches, and indeed, this is the thickness range recommended by ENERGY STAR®.
