The first 3 in. of home insulation you add to a bare ceiling or wall will yield huge savings. Adding another 3 in. will increase energy savings, but not to as great a degree. For charts showing the Department of Energy’s optimal amounts of home insulation to install, check the insulation manufacturers association at naima.org. Their recommendations are based on climate, fuel costs and other factors. Adding more will give you a diminishing return on your investment.
The payback period for retrofitting home insulation varies greatly, but studies show that added insulation usually pays for itself in saved energy costs within 5 to 10 years. In Minnesota, a typical payback period might be five or six years. Payback in more temperate areas takes longer, but remember that home insulation reduces air conditioning costs too.
