Having the right amount of fiber glass or mineral wool insulation in your house is critical to keeping your home more comfortable and to reducing* your monthly heating and cooling bills. NAIMA and the U.S. Department of Energy (DOE) want you to know just how much insulation R-value is right for the climate in which you live. That’s why DOE developed the map below.

Just follow these simple steps to maximize the comfort and energy efficiency of your home through insulation:

1) Identify Your Insulation Zone: Find the approximate location of your hometown using the DOE Insulation Zone map below. Note: if your town is located near a border between two insulation zones, choose the zone for the colder climate to ensure that you have adequate insulation.

2) Find Your R-Value Needs: Find your correct zone on the chart below the map to determine how much insulation, measured in R-value, your home’s ceilings, walls and basement should have to maximize your energy efficiency.

3) Talk to a Professional: Contact your local professional insulation contractor, building materials supply store or building code official, to compare your existing insulation R-value with Department of Energy recommendations.

*Savings vary. Find out why in the seller’s fact sheet on R-values. Higher R-values mean greater insulation values.
