Recommended Insulation R-Values By U.S. Regions

DOE Map Provides Recommended Insulation Levels

The Department of Energy (DOE) has created a detailed map for recommended R-Values throughout the United States. This map reflects their research on the different climate zones and number of heating and cooling days. If the only consideration is energy efficiency, more is always better. However, the DOE map suggests the appropriate insulation level, which is cost-effective. An uninsulated attic has a wide range between R30-R60. Below is the DOE map for the Continental US, which is divided into seven (7) climate zones. The Midwest is generally covered in climate zones 3,4 and 5.
