Does Energy Efficiency Increase With More Window Panes?

When tackling a window replacement project, choosing the frame material and the desired style of operation is not enough. You must also consider the number of glass panes the window should have. Some only have one, most have two, and others have three. Many people believe, however, that energy efficiency increases with more glazing.

Does Energy Efficiency Increase With More Window Panes?

That, unfortunately, is not always the case for the most part.

Several Layers of Glass Is Better, But…

Gone are the days where a window unit only had a single pane of glass. It is good enough to provide a view of the outdoors and keep the wind out, but such a fixture is likely to allow weather conditions outside to affect the indoor temperatures. After all, a single glass pane is a poor insulator.

It is the reason why many manufacturers began building windows with either double- or triple-pane glazing. They are huge upgrades, with the latter outperforming the former. Except in extreme climates, the degree of insulation from an additional third pane is barely noticeable.

"The salesman had previously sold us new windows and was very informative and not a bit pushy. The installation was excellent and as advertised absolutely nothing was left for me to clean up. Highly recommend Renewal by Andersen of St. Louis👍"
