From energy efficiency to aesthetics to maintenance, there are many things to consider when purchasing new windows for your home. Your goal should be to settle on windows that tick all those boxes so you can ensure the best buying decision possible.

Here’s what to think about before purchasing replacement windows.

1.    Energy Efficiency

Performance criteria for windows are typically based on ratings certified by the National Fenestration Rating Council (NFRC), but there are a few factors that make a window energy efficient.

  • Quality Frame Materials: Durable, low-maintenance frame materials have the ability to reduce heat transfer while boosting insulation. The type of frame you choose will dictate the amount of thermal resistance. In general, vinyl, wood and fiberglass have the greatest thermal resistance, more so over metal.
  • Multiple Panes: If you have single pane glass, common on old windows, heat and cold air can easily escape and enter. At least two to three panes of glass are needed to provide optimal energy efficiency and reduce noise.
  • Low-E Glass: These are coatings that control heat transfer through windows, says gov, reducing energy loss by up to 50 percent. A low-e coating is a thin metal or metallic oxide layer included on the panes of glass. This lowers the U-factor of the window – the rate at which the window can conduct non-solar heat flow. Low-E glass is also responsible for reflecting ultraviolet light that can damage interior furnishings and carpeting.
  • Gas Fills: Inert gas such as argon or krypton can be used to fill the panes for higher resistance to heat flow than air.

2.    Aesthetics

With so many distinctive window styles to choose from, you are sure to find one that suits your personal taste. While you can design your own custom windows, the most common window types that do a fine job of increasing your home’s curb appeal include:

  • Double-hung: These have two operable sashes so you can tilt the window open at the bottom and top.
  • Single-hung: These have sashes to open the bottom half, while the top remains inoperable.
  • Sliding windows: These comprise one or more panels moving horizontally.
  • Awning windows: These windows, often seen over a sink or in a bathroom, have a hinge at the top.
  • Folding windows: You can fold down this type of window to get fresh air.


No matter which design you choose, you are doing your part to increase your property value as well as the aesthetics of your home.

3.    Maintenance

The best part about replacement windows is how easy it is to clean them and maintain them. With double hung, for instance, you can tilt them in to clean the outside without even having to get up on a ladder. For the least amount of maintenance, go with vinyl frames, as they don’t require nearly as much upkeep as wood or steel. Wood can rot and steel can corrode, so your best bet is to stick with vinyl for easy cleaning.
