All Renewal by Andersen windows are custom crafted from our proprietary composite material, Fibrex. Fibrex was created to combine all the low maintenance qualities of vinyl with the durability of wooden windows, so that they can give your home the best of both.
Made from 40% reclaimed wood, Fibrex holds glass with a weatherproof seal and strength twice that of vinyl. And, because it’s so strong, Fibrex frames can be narrower than standard wood or vinyl frames while supporting larger panes of glass for a great view.
Fibrex holds up better overtime, too, with a Renewal by Andersen 20-year limited warranty promising structure and color that won’t peel, flake, or fade. See all possible configurations of Fibrex frames in our gallery below.


In addition to being stronger and more energy efficient than wood and vinyl, Fibrex material is also more versatile. It can be configured to nearly any shape in manufacturing while still sealing your home against the elements. Plus, its blend of materials allows easy operation of functional windows so you’ll never have to deal with sticking or expanding.
You can also match the style of your house both inside and out with up to 51 window frame colors and stains. Vivid colors-including darker exterior colors not available elsewhere-are fused into Fibrex material. This ensures that your replacement windows will stand against climate changes, time, and regular use with fade-resistant style.
