We all know that the type of glass used in windows, along with whether it is single, double or triple paned, has a lot to do with energy efficiency, but few of us think about window frames. In reality, the choice of material and the way the frame is constructed can be just as big a factor in efficiency as the glass that is used. A triple pane window is not worth the extra cost if the frame allows air to travel freely in and out of the poorly sealed home.
Window frames come in four basic materials: wood, aluminum, vinyl and fiberglass. Each of these has different benefits and, of course, different energy efficiency characteristics. Even if you select a material that is not the most energy efficient, there are other components of window frame construction that can improve the efficiency of your windows.
When you shop for windows, you are likely to hear the term U-factor used in reference to different windows. The U-factor is the rate at which a window or door loses heat. A lower U-factor means a window is more energy efficient. A rating of 0.15 to 0.35 is a very good U-factor.
Fixed windows that do not open are the most efficient window type. They are the least likely to leak air through tiny gaps or spaces. Hinged windows, such as awning, hopper and casement windows, also have low levels of air loss. They typically form tight seals when closed. The traditional double hung window that slides open vertically is the least efficient in terms of air loss. Still, if you prefer this style, there are many very efficient double hung windows.
The most efficient windows will be vinyl or fiberglass frames with a low U-factor. Know that choosing one of these window frames means excellent window performance with very little maintenance. Choosing a window with double or triple glazing makes it even more efficient. With foam insulation used during the actual installation to fill any adjacent gaps and air spaces, you will be warm and toasty all winter, thanks to your energy efficient window frame.
We carry efficient frames in every style and colour you could possibly want. Stop by our storefront or give us a call today for your free estimate.
