Renewal by Andersen Windows compared to Vinyl Windows

Vinyl Windows
Vinyl windows are very economical and are great for a quick replacement, but these products are flawed in long term performance and customization. Over time, as your house expands and contracts with changing temperatures, your vinyl window frames will warp and make it incredibly difficult to operate them properly. In the worst cases your windows may not even maintain their full functionality after a couple years. In addition to making your windows inoperable, this warping can cause the glass in your windows to crack and need replacing.
Fibrex Windows
Our patented Fibrex material has been designed to ensure a tight seal and remain operational for the life of your new windows. We know that it’s important to match your new windows with your home’s decor, which is why we offer our Fibrex frames in a wide variety of color options. With vinyl frames from another company you’d be stuck choosing between 2 or 3 colors, while we offer different solid colors, as well as various natural wood styles. You will be amazed at the difference in look and performance of our Fibrex windows in comparison to vinyl windows.
