Proper home insulation can curb energy costs

Bookmark and Share     Return to VectrenLiveSmart.com Home

Only about 20% of homes built before 1980 are well-insulated. And given 50% to 70% of the energy used in the average American home is a result of heating and cooling, adequate insulation is critical to keep energy costs low.

Where should you insulate? ENERGY STAR, the government-backed organization that promotes energy efficiency, suggests that adding insulation to attics, floors over crawl spaces, walls and accessible basement rim joists can save homeowners up to 20% of their heating and cooling costs.

There are several different types of insulating material, each with its own characteristics and advantages. The U.S. Department of Energy’s R-Value Recommendations tool can help determine how much insulation you need in your home. R-value indicates an insulation's resistance to heat flow.

The ZIP-Code Insulation Program will tell you the most economic insulation level for your new or existing house. Watch the how-to video to learn more. For more details about insulation categories and tips for do-it-yourselfers, check out the U.S. Department of Energy Web site by clicking here.
