Checking the NFRC Label on Your Home Windows

Created by the National Fenestration Council®, the NFRC label is an energy-efficient performance rating for products including doors, skylights, and home windows. This label can distinguish the true value of your investment by providing businesses and consumers with a way to compare the energy efficiency of their products. Fortunately, for homeowners living in the Wichita, Kansas, area, you can find NFRC-certified window products at All States Home Improvement. Independently tested and clearly labeled for your viewing, these windows are equipped with the features you need to ensure you are making a smart, energy-saving decision.

The following list provides the four major NFRC measurements and detailed instructions to help you read and comprehend this label:


Usually located in the upper left corner of the label, this number indicates how well your new windows will prevent heat transfer. The range for this thermal measurement can fall anywhere from 0.20-1.20, but keep in mind that lower numbers indicate a better U-factor rating.

Solar Heat Gain Coefficient

This number measures your window’s ability to resist heat gain on a 0-1 scale and can usually be found on the upper right corner of the label. On this scale, lower numbers indicate better resistance.

Visible Transmittance

For those looking for home windows that will allow an impressive amount of natural light into their living space, this is an important number to consider. Visible transmittance refers to your window’s ability to effectively allow daylight into your home. Usually found on the bottom left corner of the label, this scale ranges from 0-1, where higher measurements indicate increased natural light exposure.

Air Leakage

No one enjoys a drafty window. To ensure your windows allow the least amount of air into your home while they are closed, look for low numbers on a range from 0.1-0.3. This measurement is usually found on the bottom right corner of the label.

All States Home Improvement completed removal and installation on 16 windows, 2 exterior doors, and a storm door in our home. They were extremely professional and detailed with discussion of the work being done from start to end; setting expectations with us and working to understand everything we wanted done so they could make sure we were satisfied. From start to finish, All States was extremely professional and customer focused.

Our new shower is perfect, we love it! The All States crew did an amazing job: they are a master at the craft. Kept us informed every step of the way. It took just one full day to pull out our old tub & transform our shower stall. If you're considering a tub-to-shower conversion, the finished product will look just like the promotional pictures. Thank you All States!

My experience with All States was outstanding from first contact to follow up after installation. Every employee we encountered was professional and courteous. The quality of the components and installation was also first class. I would recommend them for this service without hesitation.

Our experience with All States Home Improvement was awesome! We did a tub-to-walk-in shower conversion. They came out to give us a quote and show us the many options. I appreciated their patience while we decided on exactly what we wanted to buy. Our installers were both rock stars! They showed up on time, were polite, and made sure everything was cleaned up real nice. Thanks All States!

We are pleased with the results of our exterior remodel by All States. They took the time to meet with us and get to know our vision, and how they could help us achieve that vision. In the end, we got a new roof, new windows, new siding, and new gutters. They provided great crews that worked hard and efficiently. We would recommend All States to someone looking to get home improvement projects done efficiently and well, with high quality.
