Adding insulation in your attic can lower your power bill
Is there enough insulation in your attic? By adding insulation, you can improve your home's energy efficiency and save money on your electric bills.
With adequate attic insulation, your home's heating/cooling system will operate more efficiently. It will keep you cooler in the summer and warmer in winter — and it will keep more money in your wallet.

Older homes tend to have less attic insulation than newer ones. An energy audit can indicate whether additional insulation is needed.
Before adding insulation to your attic, determine how much insulation is already installed, what kind it is and how thick it is. Next, you'll need to know the R-value — which indicates the insulation's resistance to heat — of existing attic insulation. The higher the R-value, the greater the insulating effectiveness. Once you know the R-value, you can determine how much insulation to add by using the U.S. Department of Energy's Zip Code Insulation Calculator at www.ornl.gov.
Now you're ready to decide what kind of insulation to install: loose-fill or blanket (batt and roll) insulation. Loose-fill insulation consists of small particles of fiber, foam or other materials. Blanket insulation, the most common and widely available type of insulation, comes in the form of batts and rolls made from mineral wool, plastic fibers and natural fibers. Loose-fill insulation is usually less expensive to install than batt insulation. And when installed properly, loose-fill insulation can provide better coverage.
