Why? Improving the insulation in your home can be the single most effective way to save energy. In a typical home, over 45% of heat loss happens through walls, floors, and the roof. Improving insulation can help you stay warmer in the winter and cooler in the summer, reducing your heating and cooling bills.
How to install:
Professional option: Have a professional identify areas that need insulation and install it. A professional is helpful when you are remodeling or adding on to your home and you want to identify areas to re-insulate.
Do-it-yourself option: You may be able to install insulation on your own in certain areas. An attic without heating or cooling is a prime area for an insulation project with great results.
What to look for: All insulation products have an "R-value," which means the resistance of the material to heat transfer. A higher R-value means more insulation. Consult your contractor or the U.S. Department of Energy for the right R-value for your home.
Good to know:
- Seal air leaks between walls or floors in your home at the same time you improve insulation.
- Consider improving your insulation before replacing your heating or cooling system. With better insulation, a smaller furnace or air conditioning system may be sufficient.
