While both wood and vinyl frame windows have their benefits, Renewal by Andersen’s exclusive Fibrex® material offers you the best that each material has to offer. Made of 40% reclaimed wood, Fibrex® combines all the looks of wood with the convenience and low maintenance features of vinyl.
It accomplishes this with reinforced fiber strands that give Fibrex® its strength, durability, and ability to be configured to any size and shape. Fibrex® material also completely soaks in dyes and finishes, so you’ll never have to repaint your window.
Especially when paired with one of our energy efficient glasses, Fibrex® promises a window that stays looking great and keeping you comfortable for years.


Thinner frames, custom shapes, and 51 different color combinations-including darker colors and contrasting interiors-ensure there’s a window and door design option for every kind of home and homeowner. Twice as strong as vinyl, Fibrex frames hold more glass for a wide view and can be custom-made to fit almost any shape and style. Choose a functioning window in awning, casement, sliding, or double hung styles; define a room inside and out with a large specialty or picture window; or combine any for an original, multi-dimensional look. Backed by a 20-year warranty, you can be assured that your custom replacement window will look great and function exactly as it did on the day it was installed—no matter which style you decide on.
