If you are in the market for new windows, you may have come across the term "NFRC rated windows". But what does it mean and why is it important?
NFRC stands for National Fenestration Rating Council, an independent organization that provides energy performance ratings for windows, doors, and skylights. These ratings are based on a series of tests that measure the efficiency of the product in terms of thermal performance, solar heat gain, and visible light transmittance.
When looking for the best nfrc rated windows, there are a few things to consider. First, the U-factor, which measures how well the window can insulate against heat loss, is an important factor. The lower the U-factor, the better the window's insulation properties.
Another factor to consider is the solar heat gain coefficient (SHGC), which measures how much solar radiation is admitted through the window. A lower SHGC means less solar heat is admitted, making for a more comfortable and energy-efficient home.
Additionally, visible transmittance (VT) measures how much light is transmitted through the window. High VT windows provide more natural light, which can be beneficial for improving mood and productivity.
With these factors in mind, the best nfrc rated windows can vary depending on the specific needs and preferences of the homeowner. However, several brands have consistently scored high in NFRC ratings.
Andersen Windows, for example, has a range of products that have received high ratings for energy efficiency. Their SmartSun glass, for instance, blocks 95% of harmful UV rays while still allowing natural light to enter, and their triple-pane glass options provide excellent insulation properties.
Pella Windows, another top-rated brand, offers products with low U-factors and SHGCs, providing premium energy efficiency. Their Architect Series also includes patent-pending technology that allows for increased energy efficiency without sacrificing style or design.
Milgard Windows and Doors, a brand primarily serving the West Coast, also offers products with high NFRC ratings. Their Essence Series, for instance, combines a low U-factor with a high SHGC, providing both insulation and solar heat gain capabilities, which can be beneficial in cooler regions.
In conclusion, when looking for the best nfrc rated windows, it is important to consider factors such as U-factor, SHGC, and VT, as well as personal preferences. Several brands, including Andersen, Pella, and Milgard, consistently rank high in energy performance ratings and offer a variety of products to fit individual needs. Investing in high-quality, energy-efficient windows can result in significant long-term savings on energy bills while improving the overall comfort and value of your home.
