Where to Insulate in a Home

“One of the basic remedies in lowering your energy bills is to correctly insulate your home. When proper insulation is done at home, you will be surprised on how it makes a huge difference in your next billing.”

For optimal energy efficiency, your home should be properly insulated from the roof down to its foundation. In addition to insulation, consider moisture and air leakage control in each area of your house. If radon is an issue where you live, you’ll also need to consider radon and radon-resistant construction techniques as you research foundation insulation options. In addition, if you live in an area with termites, you’ll have to consider how termite protection will affect the choice and placement of insulation in your home.

Attic Insulation

Loose-fill or batt insulation is typically installed in an attic. Loose-fill insulation is usually less expensive to install than batt insulation, and provides better coverage when installed properly. See more on different types of insulation. Before insulating, seal any air leaks and make roof and other necessary repairs. If it is located in a conditioned part of the house, also remember to insulate and air seal your attic access.

Insulate and air seal any knee walls — vertical walls with attic space directly behind them — in your home as well. In addition, if you’re building a new home or remodeling, make sure any attic decking that provides additional storage space or a platform for a heating and/or cooling unit or hot water tank is raised above the ceiling joists to leave room for adequate insulation. Finally, if you live in a hot or warm climate, consider installing a radiant barrier in your attic to reduce summer heat gain.

Duct Insulation

If the ducts in your home are in unconditioned space, seal and insulate them. If you’re building a new house, place ducts in the conditioned space to avoid the energy losses associated with most duct systems.
