Renewal by Andersen Signature Fibrex® Material

Fibrex® frames are completely saturated with color during manufacturing, so you never have to worry about paint cracking or flaking off.
All Renewal by Andersen windows are also guaranteed to function just as well as the day they were installed, so frames will never expand or bow.
Made from 40% recycled wood fiber by weight, Fibrex® provides the strength of wooden windows with the versatility of vinyl.
The unique blend of Fibrex® material allows your windows to be supported by narrow frames for a wide, sleek glass area.
