A window’s U-Value, also described as U-Factor, measures the rate the window transfers non-solar heat. One of the most important ratings to pay attention to when looking for new windows is the glasses U-Value. Today we are going to lift the veil off of some of these terms to help inform your next window purchase. Stickers and fliers on the windows mentioning things like “window U-value” and “SHGC rating” could be a bit intimidating for folks not sure which window is right for their home (or could even be interpreted as marketing nonsense).

That being said, shopping for new windows can be quite daunting. Advancements in window technology allow homeowners to lower heating and cooling costs and significantly increase comfort as well. Long gone are the days of windows existing to purely to block the elements from entering a home.
