Knowing the right R-value* for your home is vital information when adding insulation. With too low an R-value*, you risk an inefficient home and bigger heating bills. Thankfully, the U.S. Department of Energy has provided a convenient R-value* guide for consumers.

Energy Star identified 8 regions with different R-value* needs across the United States. Homeowners living in the South and Southwest have the least demanding insulation needs, while homes in the North need higher and higher R-values to keep warm.

Log on to the Energy Star website to see where your home lies on the R-value* map. You can log back on here for more insulation tips as well.

* R means resistance to heat flow. The higher the R-value, the greater the insulating power. Compare insulation R-values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in. Also, your fuel savings from insulation will depend upon the climate, the type and size of your house, the amount of insulation already in your house, and your fuel use patterns and family size. If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-value, it is essential that this insulation be installed properly.
