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.

Instead of focusing on the individual parts of the window, it is better to tackle what’s more important.

"Renewal was fantastic! They kept you in the loop from ordering to installation. They informed you at every step of the process of what was happening. The installers were kind, courteous, and professional. Everything was cleaned up after the installation. It was as if they hadn't been there except to see your beautiful new windows. I highly recommend them."

"3rd time using RBA for window replacement. Again, a very positive experience, the windows are great, the installation was done right, the professionalism was apparent from start to finish. Still have existing windows to be replaced and will definitely use RBA again to do it in the future."

"Renewal by Andersen was a good experience for us in replacement of our windows. From the initial meeting with the sales representative, Leslie, through the waiting period for manufacturing, and then to the installment process, our experience was excellent! Communication is key for me and we were kept informed and updated as our windows were being ordered and manufactured. Calls to update us on the installation process were welcomed and appreciated. They know how much is too much so they don't pester you with unnecessary contact. We love our new windows!!! Did I say that already??😂 We can tell a major difference in reduced Street noise and also the temperature at our windows. Excellent company, highly recommend!!"
