Where to Insulate
Checking your current attic insulation depth is a good first step. You need up to 19 inches (or R-50). If you
don't have enough, it may be an indication that your home is underinsulated and may not be properly
sealed. Adding insulation to underinsulated areas and sealing air leaks are the fastest, easiest ways to
help you lower your energy bill.
Insulation R-Value
R-value is the measure of a material's ability to resist heat conduction. The greater the material's R-value,
the better it performs as an insulator. All values assigned to insulation are based on specific thicknesses
and are usually noted on the packaging. Compressing or otherwise reducing the thickness of insulation
reduces its ability to resist conduction.
