Attic insulation near me

Determine your current R-value

Now that you’ve measured your insulation depth, you can reference the image below to see what your approximate R-value is.

For example, if you measured your fiberglass insulation to be 9” deep, your current attic insulation R-value would be an R-26 and would require an additional 3.5” of insulation at minimum throughout just to meet the R-38 code.

The image below is for Fiberglass insulation only.

For cellulose insulated attics, the process is similar but you’ll just multiply your depth by 3.5 and that should give you an approximate R-value.

Figure the amount of insulation you need to add

If you’re wanting to reach an R38 (12.75” deep) and you have an R26 (9” deep), you need to add an additional 3.75” of insulation to your attic.
