How to Make Your Windows More Energy Efficient

Mar 4, 2015

If installing new, energy efficient windows in your home isn’t an option, here are some ways to make your current windows more energy efficient. As a result, you can enjoy lower energy bills and a more comfortable home!

Cold Weather Tips

  • Fixing a heavy-duty, clear plastic sheet on a frame or taping a clear plastic film to the inside of your window frames will reduce drafts.
  • Consider installing tight-fitting, insulating window shades on windows after weatherizing for extra sealing.
  • Make effective use of curtains and shades by closing them at night to protect against drafts, and opening them during the day to let in warm sunlight.
  • Installing exterior/interior storm windows can reduce heat loss by approximately 10-20% depending on the type of window.
  • Repair and weatherize any storm windows you have currently installed.

Warm Weather Tips

  • Try using white window shades, drapes, or blinds, which will reflect heat away from the house.
  • Close curtains on south and west-facing windows during the day to block excess heat from entering the house.
  • Create shade by installing awnings on south and west-facing windows.
  • Reduce solar heat gain by applying a reflective film on south-facing windows.

Long Term Saving Tip

While the a.m. tips will help make your current windows work more efficiently, for long term savings, consider replacing your windows with high-performance ones. It might mean spending more money initially, but your investment will pay off in the long run.
