At first glance, it may be hard to differentiate our High-Performance™ glass options from others. Nevertheless, a closer look at the manufacturing process will reveal why our glass remains a market leader to this day. Let the top provider of replacement windows in Waukesha discuss why the glass from Renewal by Anderson is superior.

Insulated Glazing

Also known as double glazing, this process incorporates a coated glass layer to the windows, preventing heat from escaping. This thermally insulates the window and improves the energy efficiency of your home. After all, we believe that two panes are better than one. We also optimize the air space width between the two glass panes, ensuring the best thermal performance.


Glass spacers determine the amount of heat or cold that is able to pass through the window. The quality of the materials used to manufacture these spacers, along with their thermal properties, is crucial to their performance. This is why we use stainless steel, instead of aluminum that other manufacturers use. Our low-conductivity spacers provide more heat resistance and promote better stability of the glass. Inferior spacers may damage the seals, and compromise the thermal performance of the window panes.

Argon Gas Filling

Replacing the air between the panes with an inert gas further increase the energy efficiency of our double glazed picture windows in Waukesha. One of the best gases used today is argon, as it offers better insulation since it is heavier than air. Argon also boosts the sound-proofing properties of the window. Argon-filled windows provide better protection from harmful UV rays.

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.
