What Is a Good U-Factor for a Window?
If you are looking to upgrade the windows at your home with more energy-efficient options, you’ve likely come across the term “U-factor” in your search. What is U-factor exactly? Well, ENERGY STAR says that a U-factor “measures the rate of heat transfer and tells you how well the window insulates.” But, what does this mean and how can you tell what a good U-factor is for your new windows? Let’s explore further.
U-Factor Rating Scale
The U-factor scale ranges from 0.25 to 1.25. The lower the U-factor, the better the window insulates. This means that lower U-factor values are associated with more energy-efficient windows. For example, a window with a U-factor of 0.35 would be considered more energy efficient than a window with a U-factor of 1.25. And, the window with the 0.35 U-factor would insulate better than the window with a 1.25 U-factor.
