An investment in attic insulation in most older (and some newer) houses will pay for itself in 1-6 years. Adding insulation also improves comfort by reducing temperature swings.
Use the tool below to find out how much you could save on heating and cooling in a year by improving your attic insulation to 18" (R-50).*
*The Rule Your Attic Tool is designed to give you an estimate of heating and cooling costs based on the size of your home, heating system age or efficiency, and attic insulation level. As an estimate, the heating cost and payback period should be used as a guide to determine cost-effectiveness and is not a guarantee of utility costs or savings.
