Energy Efficiency of Renewal by Andersen® Windows

Renewal by Andersen puts much time and effort into ensuring the lasting energy efficiency of the windows they produce. Each Andersen window is EnergyStar rated. Each one utilizes materials that have been specifically designed for increased energy efficiency, including Renewal’s exclusive Fibrex material and Low-E glass packages. You won’t find a window company with a better underst anding of our deeper dedication to energy efficient windows. The need to save money on monthly energy bills is something to which every homeowner can relate. It seems that every year the prices of gas, oil, and electricity get higher and higher and keeping a home bright and comfortable gets more and more expensive. Renewal by Andersen seeks to counteract those skyrocketing prices with advanced windows that take into account the factors that lead to energy loss or overuse. Unlike wood or vinyl windows, which will crack or leak over time, Renewal by Andersen’s Fibrex windows remain intact through even the harshest weather. That means that your costly heating or cooling energy remains trapped within your home, allowing your temperature regulating systems to work at peak efficiency. Like their Fibrex frames, the Low-E glass used in each Renewal by Andersen window helps to limit the work load of your heating and cooling systems. They do so by limiting the penetration of infrared sun rays, which cause temperature fluctuations in your home if allowed to enter through your windows. Those fluctuations cause your heating and cooling systems to constantly kick on and off, which uses up quite a bit of energy. With Low-E glass, IR rays are kept at bay and your heating and cooling systems will work only as directed.

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
