The ABCs of Insulation
The FTC requires insulation manufacturers and sellers to test and label their products. Generally, the higher the “R-value” the more energy you can save. When you buy insulation, installers and retailers have to give you an R-value fact sheet. New home sellers must give you information about the type, thickness, and R-value of the insulation in each part of the house. Many state or local building codes include minimum requirements for home insulation. Be sure your new home or home addition meets those codes. It will save you money in the long run.
The amount of insulation you need depends on the climate, the part of the house, and the type of heating and cooling systems (gas, oil, or electric) you have. Your attic is the best place to start. The Department of Energy has an online calculator to help you decide what’s right for you. Visit the Zip Code Insulation Program website.
