  3. Ask for ENERGY STAR when ordering

    All ENERGY STAR window, door, and skylight manufacturer partners offer products that meet the ENERGY STAR criteria. The key is to ask for them. Find an ENERGY STAR Window, Door, or Skylight Manufacturer.

    Windows, doors, and skylights should display an official ENERGY STAR label (examples below) or equivalent custom label, next to the NFRC label. There are a variety of custom labels, but all should include the same elements as the official label:

    • The ENERGY STAR Certification Mark
    • A map showing where the product is qualified
    • A qualification statement

  4. Have Windows, Doors, and Skylights Properly Installed

    To get the most out of your windows, doors, and skylights, have them installed by trained professionals according to manufacturer instructions. Otherwise, your warranty may be void. When hiring a contractor, interview candidates Exit ENERGY STAR and ask for references. If installation requires scraping lead-based paint, be sure to take proper precautions. Exit ENERGY STAR
