Video: The Undisputed Benefits of Andersen’s Low-E4® Glass

March 13, 2018


For more than 110 years, Andersen Corporation has been pioneering one window industry standard after another. Our parent company was behind the first mass-produced window to improve affordability, and the first double-pane window to boost energy efficiency. Then Andersen developed the insulating Low-E glass to allow more and larger window installation without sacrificing performance.

For the longest time, Low-E glass has been the last leap forward in glass technology until the introduction of the Low-E4® glass. If you ask Renewal by Andersen® of Milwaukee, these are the most notable reasons why it makes the best replacement windows:

Easy Maintenance

Low-E4 glass reduces the amount of time and cost spent on upkeep. During manufacturing, a microscopic titanium dioxide coating is directly applied to the outside surface of its exterior glass. When exposed to sufficient sunlight, this invisible coating reacts to the sun’s UV radiation and starts photocatalytic action. This chemical process loosens the dirt, making it easy to wash it away with water.

Also, the titanium dioxide coating renders the glass surface smooth to shed water better. When the sun activates the glass, its surface’s evaporation rate increases to dry faster and reduce water spotting up to 99 percent.

High Glass-Breakage Resistance

Every double-hung, picture and casement window with Low-E4 glass inspires confidence and peace of mind because it’s built to last. Its interior pane is heat-strengthened and offers better resistance to breakage. Covered with a protective film, you can rest assured it can stay intact and scratch-free during transport from our manufacturing facility to your home.

Exceptional Thermal Insulation

Our most energy-efficient Low-E4 glass option, the SmartSun™ glass, has a U-factor of 0.24, which meets ENERGY STAR®’s requirements for homes in the Northern Climate Zone. By blocking 72 percent of solar heat, it’s 70 percent and 49 percent more energy-efficient in summer and winter, respectively, compared to ordinary double-pane windows.

Outstanding UV Protection

Our SmartSun glass only allows 5% of UV rays to pass through it. As a result, you reduce the exposure of your valuables to UV radiation to keep them looking beautiful bold or vibrant for a longer period.

Excellent Visible Light Transfer

Bay, bow, sliding and specialty windows with SmartSun glass filter out most of the sun’s heat-causing infrared and damaging UV rays while providing adequate daylighting. Letting in 65 percent of sunshine through, its high performance has virtually no effect on the color and clarity of the light that enters your home.

Remarkable Noise Abatement

Any Low-E4 glass option makes a great investment for peace and quiet. All of our glass packages come with two panes separated by an optimum distance to block sound effectively. We also use an argon gas blend filling to enhance the soundproofing quality of our Low-E4 glass.

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!!!
