ENERGY STAR – Certified Windows and Door

ENERGY STAR – Certified Windows and Doors are a great way to save money on energy bills. They meet strict energy efficiency criteria set by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE)

When you buy ENERGY STAR – Certified u s window and door, you will get an Energy Guide label that shows how much energy your new windows or doors can save over their lifetime. The label also shows whether the windows are eligible for a tax credit or rebate from your utility company or state government agency

You can use an ENERGY STAR certified window to compare its energy performance with other windows, but it is not an accurate comparison between different brands or types of windows. ENERGY STAR certified windows may have different dimensions, frame styles, glass thicknesses and other features that affect their energy performance more than their certification status does
