Windows

Windows can be one of your home’s most attractive features. Windows provide views, daylight, ventilation and heat from the sun in the winter. Unfortunately, heat moving in and out of your home through windows can increase your heating and air conditioning bills. Energy-efficient windows and measures to reduce heat gain and loss can help save energy and reduce energy bills.

Look for the ENERGY STAR label when buying new windows. Also review ratings from the National Fenestration Rating Council (NFRC). NFRC ratings are included on all ENERGY STAR certified windows and provide a reliable way to determine a window’s energy properties and compare products.

  • Close your curtains and shades at night to protect against cold drafts; open them during the day to let in warming sunlight.
  • Apply low-e film on the inside of your windows to keep heat from radiating out. Films are rated by the NFRC and will be rated by the Attachments Energy Rating Council (AERC).
  • Repair and weatherize your current storm windows, if necessary.
  • Install white window shades, drapes, or blinds to reflect heat away from the house. It is always best to install exterior shades whenever possible.
  • Close curtains on south- and west-facing windows during the day.
  • Install awnings on south- and west-facing windows to create shade.
  • Apply sun-control or other reflective films on south-facing windows to reduce solar heat gain.
