Installing EnergyStar Windows For Maximum Efficiency

Installing EnergyStar Windows For Maximum Efficiency

Installing double-paned windows can help cut down the energy costs of heating and cooling by providing an extra layer of insulation. By choosing replacement windows certified as energy-efficient and given the Energy Star seal, you can save up to 15 percent on energy bills. Actual savings vary by location, but in some areas, estimates were over $200 and up to 2,825 pounds of carbon dioxide saved in a year.  Here is a step by step guide on how to choose the right windows for your home.

Step 1:  Visit the EnergyStar website at to find out about the climate in the region you live in, this will help determine which products are most compatible.

Step 2:  Locate the National Fenestration Rating Council label, the U-Factor rating and the Solar Heat Gain Coefficient rating on the label,  on any windows you want to buy. The NFRC label shows the various ratings that apply to the window, the U-Factor measures the amount of heat that can pass from the inside to the outside and the SHGC is a measure of the amount of heat that can pass through the window from the outside to the inside.  Make sure these labels match up with the EnergyStar rating for your climate zone is.

Step 3:  Choose wood, vinyl or fiberglass framing materials or fiberglass frames filled with insulating to help keep the heat from escaping around the window.

Step 4:  Apply weather stripping and caulk as necessary, and use heavy drapes in the winter to maximize insulation. Consider installing awnings to shade the windows in the hot weather, or plant deciduous trees near south windows to shade them in the summer and allow the sun to come through in the winter.
