November 14, 2016

When you venture on a window replacement project, you can see countless window advertisements promising excellent features. Considering the sheer number of options, it can be daunting to identify which products actually perform. Let Renewal by Andersen® of Milwaukee help you understand window labels so you can choose better materials for your replacement units.

NFRC and ENERGY STAR® Labels

The National Fenestration Rating Council (NFRC) is a non-profit organization that tests, certifies, and brands doors and windows based on their energy performance. They help homeowners make a sound decision when it comes to shopping for these products.

ENERGY STAR, on the other hand, is a voluntary platform initiated by the US Environmental Protection Agency. This sets stringent criteria to determine the durability and energy efficiency of products. When you see this label on your replacement windows in Milwaukee, it means you can expect quality performance and longevity.

Energy Performance Ratings

Look for the NFRC and ENERGY STAR labels on the window, as they usually contain information regarding energy efficiency. Here are a few terms you need to be familiar with:

  1. Visible Transmittance
    This specifies the expanse of light that goes through a product. It is often portrayed as a number between 0 and 1. A higher value means more light can enter through your window.
  2. U-Factor
    This rate measures the windows’ resistance to heat flow and typically registers between 0.20 and 1.20. Products with a higher value have poor insulating properties. Only a few window choices contain extremely low U-factor like our casement window in Milwaukee. This option is highly energy-efficient and can provide your home with great savings.
  3. Air Leakage
    This indicates the rate of air circulation in windows and doors. A low value means that the seals are tight, preventing leakage and providing more energy savings.

As one of the top providers of specialty windows in Milwaukee, WI, we want you to understand these ratings so you can choose better windows. You can also turn to us for high-quality replacement units that can provide your home with lasting value and performance. Call us today at (262) 522-3034 to learn more about our options.

Hear From Our Customers

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!!!

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.
