What to Consider When Choosing Energy-Efficient Windows ?

Energy-efficient windows add value to a home as well as enhance its curb appeal. There's so much more to appreciate. If you're in the market for replacement windows, take a moment to understand some key features of windows in general. Doing so will help you make the best buying decision in the shortest time.

Key Features


A window's glass panes are referred to as glazing. Therefore, a window with two panes together is called a double-glazed window. Three panes equal a triple-glazed window.
Energy Efficient Windows

Energy-efficient windows have a microscopic film coating that protects the windows from harmful UV rays emitted from the sun. The coating also shields against the sun's heat and cold weather.
Spacers and Gas Fills

Gas fills between glazing block air from coming inside or going outside of the home thus making the windows more energy-efficient. Spacers can be used instead. They are plastic, foams, or metals that are tightly sealed between panes to keep air out.

Operating Type

Windows may open and close in different ways. Some are fixed, while others are tilt and turn, and yet others are single-hung or double-hung. A window's operating type affects how it keeps heat and cold air inside.


Window frames affect insulation too. Some denser frame materials have greater insulation properties than thinner ones.

Do Energy Efficient Windows Really Provide Value?

Energy-efficient windows can save you hundreds on your utility bills. Moreover, upgrading enables you to enjoy a more comfortable home atmosphere. These factors alone make an investment in energy-efficient windows worthwhile.

It's also beneficial to consider the advantages of double-glazed and triple-glazed windows. They offer even more protection because fillers and coatings can be added on and between each pane. All this helps you save on heating and cooling your home.

Benefits of Coatings and Fillers for Triple-Glazed Panes

Argon Gas

Argon gas offers insulation protection to keep heat inside your home.

Krypton Gas

A step up from Argon, Krypton gas is appropriate for triple-glazed windows because they have smaller gaps between the panes.

Low-emissivity (Low-E) Film

Low-E coatings significantly block the transfer of heat. They can add 40 to 50 percent in energy savings!

Look for the U-Factor

The heat transfer rate on a window (or door) is called the U-factor. The lower the U-factor rate, the higher the insulation capabilities. A high U-factor means that more air will pass through the window.
