When you’re buying new sliding or casement windows for your home, it’s often recommended that you look for the ratings to ensure that you’re getting a high-quality window that’s also energy efficient. During this stage, you need to look for two labels from two different entities: ENERGY STAR® and the NFRC. But what exactly is the difference between these two organizations?
In this article, Renewal by Andersen® of Sacramento reveals the differences between the NFRC and ENERGY STAR.
The NFRC
The NFRC is one of the entities that helps determine the energy efficiency of a door or window. Compared to ENERGY STAR, they’re a nonprofit organization that recognizes certifying bodies for window and door ratings. Apart from that, they’re also the ones who came up with the five ratings who helps you determine how energy-efficient a window is: the U-factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance, Air Leakage and Condensation Resistance.
To install an NFRC certified window in your home, don’t hesitate to turn to residential window contractor, Renewal by Andersen of Sacramento.
ENERGY STAR
On the other hand, ENERGY STAR is an organization that not only provides their label to products that meets the ratings of the NFRC; in fact, the product must also meet the strict criteria set by the U.S. Government. So long as the window meets these criteria, they’ll qualify for both an NFRC and ENERGY STAR label, proving that they are indeed as energy efficient as they claimed to be.
Unlike the NFRC, however, which bases their ratings on five criteria, ENERGY STAR qualification only requires a product to meet the required U-factor and SHGC ratings.
