How do I know if my attic is properly insulated?
-Jennifer, Athens

Heat flows naturally from warm places to cooler ones. Without insulation, heat can flow freely in and out of your home, letting warm air escape in winter and letting warm air enter in summer. Insulation decreases heat flow, helping maintain a more uniform and comfortable temperature throughout your home year-round.

You can generally get the most savings by ensuring that your attic is properly insulated. This includes insulating your attic hatch and sealing it with weatherstripping.

You can determine the R-value of existing insulation by determining the type of insulation and the thickness. Often, using a ruler to measure the thickness may be the best method.

To find the proper insulation R-Values for specific areas in the home, visit the Georgia Department of Energy web site at state.ga.us. At a minimum, insulation should meet local building codes. However, the Department of Energy and Energy Star have recommendations on their websites for suggested R-values to make your home as energy efficient as possible.
