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. At Renewal by Andersen®, we believe our outstanding whole-window performance is a combination of not just glass, but also framing material and professional installation.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"I replaced my front door and several windows. The install team did a great job with installation and clean up. Even covered floors and stairs. The team was very courteous and did a very professional job. Now our windows look great and we love our new door. I would recommend Renewal by Anderson in a heartbeat."
