Adequately insulating your attic can dramatically lower your energy costs during winter and summer. Obviously, the more insulation, the better, but you also want to make sure you achieve a good balance that doesn’t eliminate any extra storage space you may have overhead.
The Department of Energy has specific recommendations and requirements for insulation thickness that are based on energy costs and climate statistics for different parts of the country. You can find out what the required insulation thickness for your area is by contacting your energy provider.
