How Much Insulation Do You Need in Your Home

By: Danny Lipford

Insulation in your home is important to reduce heat loss and gain and save energy. How well a particular type of insulation works is determined by its R-value, which is a measure of the insulation’s resistance to the transfer of heat.

Charts are available at your local home center and online at the U.S. Department of Energy Energy Savers that give the recommended R-value for your area of the country.

Install rolls or batts of faced insulation in an uninsulated attic, with the paper facing down toward the ceiling. For an attic that already has insulation, install unfaced rolls or batts of insulation on top of the existing insulation. Another option is to blow loose fiberglass or cellulose insulation on top of the existing insulation.
