Replace or Update?

You can either choose to replace your windows or update your current ones. It’s not that difficult to take steps to ensure energy efficiency if your windows are already fairly new. Use the following tips to make sure your newer windows aren’t hurting your wallet.


  • Check for any air leaks around the perimeter.
  • Caulk and weatherstrip around the edges of the windows. Make sure all the seals are tight, so no air escapes.
  • You can add energy-efficient window coverings that improve the way your house preserves the temperature.
  • Awnings can also provide enough shade to keep the heat of the sun out.


When you replace your window, you need to make a few important decisions regarding the type of window to install. These are the most important characteristics surrounding new windows:

  • The type of frame and glaze
  • Gas fills and spacers
  • Operation types

If you’re in a colder climate, selection gas-filled windows could be a much better choice for keeping the heat in your home. Choosing a window with a low U-factor is also important regardless of the type of climate you live in. The U-factor is the rate the windows conduct non-solar heat flow.

Look for windows that have the “Energy Star” or “NFRC” labels on them. These are the best-rated windows for going green and will save you the most money on your utility bill.
