With energy prices on the rise, more and more homeowners are installing energy-efficient windows. But what exactly makes a window energy-efficient? It takes more than just one feature to make a window energy-efficient. When looking for a window replacement, you need to take a look at its entire performance.
Abby Windows & Exteriors, one of the top window companies in the state, shows you how different factors can affect a window’s performance below.Glass
Glass is a poor insulator. That’s why single-pane windows aren’t the most cost-or-energy-efficient option. What about double-paned windows then? Does adding more glass panes make a difference? The pocket of air between the two glass panes will slow down heat transfer, so yes, having more panes does make a difference. However, having more window panes doesn’t directly translate to higher energy-efficiency.
Take for example triple-pane windows. A higher number of window panes means should mean they’re more energy-efficient, right? Well, not exactly. It is slightly more energy-efficient, but it barely makes a difference. And since triple-pane windows cost 25% to 30% more than double-pane windows, you’re essentially paying a premium for a slightly more energy-efficient window.Frame Materials
Another factor to consider is the frame material. Apart from durability, you need to look at a material’s thermal conductivity or ability to transfer heat. The higher a material’s thermal conductivity, the less energy-efficient it is.Installation Keep in mind that no matter how energy-efficient a window is, it won’t be able to insulate your home if it isn’t installed properly. Windows that weren’t installed properly will likely have gaps through which cool or warm air can leak out. That’s why you should only hire certified window installation contractors.
