Understanding NFRC Labels

Understanding NFRC Labels

March 11, 2019

When choosing components for your home, you want the best quality you can afford. However, as Renewal by Andersen® of Milwaukee points out, there are more factors to consider rather than how your windows are made and how long they may last.

Its energy efficiency can also play a factor. When choosing replacement windows, here are the labels to watch out for so you can gauge their energy performance.

Solar Heat Gain Coefficient

This can come in handy when you would like to cool down during the summer season. This is because it will hint how a product can resist unwanted heat gain. To measure this, look for low numbers ranging from 0 to 1  on the label. This usually means that you’ll be spending less on cooling.

U-Factor

While the first focuses on keeping the heat out, this one is the opposite. A double-hung window with a low number means it can prevent heat from escaping from the room. Look for one that ranges from 0.20 to 1.20.

Visible Transmittance

Temperature is not the only factor to consider when shopping for a window. If a label has a high number ranging from 0 to 1 in its visible transmittance, it shows how well the product can effectively light your interior with daylight. This way, you won’t have to rely solely on artificial lighting.

Air Leakage

As already stated in its name, the air leakage number will help you measure how much air those picture windows you just bought will be allowed into your room. Keep an eye out on low numbers ranging from 0.1 to 0.3.

Condensation Resistance

While optional in an NFRC label, the CR label gives you an overview on how well the product’s inside surface will be able to formation of condensation. The higher the number, the better they will be at resisting condensation.

Hear From Our Customers

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!
