Step 1
Visit the Department of Energy's Web site for specific information tailored to your Zip code. (See energy.gov.)

Step 3
Know what type of heating and cooling you use (natural gas, electric, etc.). These are used in figuring the needed R-values for your home.

Step 4
Notice that the column on the left of the MEC lists the areas where insulation is used. The middle column tells you what the best R-value is for that area, and the right column tells you the installation method required.
