Where Design, Engineering and Experience Come together



Fibrex® material is twice as strong as vinyl, which retains its stability and rigidity in all climates unlike vinyl that expands and contracts which can cause cracks, bowing and leakage of air and water. Our Fibrex® material reduces maintenance costs and provides insulation equal to that of traditional wood frames with low maintenance that never requires painting¹, and will not crack, pit, corrode, or rot¹.

HeatLock™ glass reflects escaping heat back into the room in winter which compared to ordinary dual-pane glass saves 45% more energy efficiency³.

The Fibrex® frames on Renewal by Andersen® of Milwaukee windows create a weather-tight seal that will hold up against even the harshest Wisconsin winters, never springing leaks or gaps. During the warmer months, Fibrex® does not conduct heat as well as wood or vinyl, making it easier to maintain a comfortable temperature in your home without your cooling systems working overtime.

Renewal by Andersen® of Milwaukee continues to work towards more advanced, more energy efficient materials each year, and are leading the industry in the push for more “Green” production practices. This is evident in the sustained production process of Fibrex®, in which excess material from one production cycle is used in the next. Unlike the processes behind wood and vinyl window materials, little to no excess material from the process behind Fibrex® ends up in landfills. It is truly a sustainable material from production, to installation, and beyond.

The glass panels of Renewal by Andersen® of Milwaukee windows also offer energy saving benefits. In the summer months, when the bright Milwaukee sunshine bares down on your home, the double pane Low- E glass will limit the amount of UV and Infrared rays that penetrate into your home. When you have inferior windows, those rays will cause the temperature in your home to rise and your cooling systems to work harder to counteract.
