Understanding the ENERGY STAR® and NFRC Labels on Windows

When improving their homes, a common goal among modern homeowners is to make sure their house becomes as energy-efficient as possible. One of the best ways to do that is to install high-performance replacement windows. As energy-efficient windows can come with various labels, it can be tricky to know if you’re choosing the right option for your home.

If your goal is to save energy more with your upgrade, it’s a good idea to learn more about these labels, so you can be sure you’re investing in worthy units. Here’s a quick guide from Renewal by Andersen® of Atlanta that will make it easier to pick the most suitable units for your needs.

Decoding ENERGY STAR® Labels 

If there’s one thing you should look for when shopping for new windows – no matter what your goal is – it’s the ENERGY STAR label. This recognition is issued by the government, and for a window to earn this label, it has to meet stringent requirements that are specific to your climate. Once a window replacement unit has the ENERGY STAR label on it, it means it is designed to help you achieve a more energy-efficient home.

Reading NFRC Labels

An independent organization, the National Fenestration Rating Council (NFRC) rates windows for their energy efficiency. You can use the figures on the label to choose the most energy-efficient model possible for your home.

The NFRC considers a handful of factors when certifying a specific model. Some of the information you can learn from this label includes how much light can pass through your window, how much air leaks around the unit, as well as how effective the window is at keeping your home more comfortable.
