• Adding attic insulation is an energy-saving measure that homeowners should consider if they have less than 12 inches of insulation in their home. Attic insulation is not difficult to install, inexpensive and nearly maintenance free.

    Energy Savings

    The U.S. Department of Housing and Urban Development reports that energy savings from proper attic insulation range from 13 percent to 21 percent.

    Reduces Heat Loss

    Attic insulation reduces the heat loss from a home during the winter heating season, thereby reducing the amount of money spent on heating the home.

    Reduces Cooling Costs

    Insulation also saves on cooling costs. Insulation reduces the amount of hot attic air conducted into the home.

    Amount of Insulation Needed

    The recommended amount of attic insulation varies by geographic region. Consult the U.S. Department of Energy guidelines to find out their current recommendation for your home.

    Maximum Benefit

    Insulated attics must be ventilated and properly sealed. A vapor barrier is needed on the warm side of the insulation in order to prevent moisture problems.
