Adding insulation to the attic is relatively easy and very cost effective. To find out if you have enough attic insulation, measure the thickness of the insulation. If it is less than R-30 (11 inches of fiber glass or rock wool or 8 inches of cellulose), you could probably benefit by adding more. Most U.S. homes should have between R-30 and R-60 insulation in the attic. Don’t forget the attic trap or access door.

If your attic has enough insulation and your home still feels drafty and cold in the winter or too warm in the summer, chances are you need to add insulation to the exterior walls as well. This is a more expensive measure that usually requires a contractor, but it may be worth the cost if you live in a very hot or cold climate. If you replace the exterior siding on your home, you should consider adding insulation at the same time.

Test Your Attic IQ

1. Air movement through a vented attic reduces cooling load.
FALSE: In vented attics radiant heat from the roof deck increases the attic temperature substantially.

2. Venting attics remove moisture.
FALSE: In hot, humid climates, the best way to prevent moisture condensation is to prevent moisture all together by sealing the attic from outside temperatures.

3. Closed attics are more cost-effective and energy-efficient than vented attics.
TRUE: Closed attics are really the smarter choice!
