Vinyl Windows vs. Fibrex® Replacement Windows

You can rely on Renewal by Andersen replacement windows and doors for unmatched quality and innovation. Our patented material – Fibrex® – is just one example of why we are a leading manufacturer.

Fibrex® offers a solution to weighing the pros and cons of vinyl, wood, and aluminum. Fibrex combines the strength and visual appeal of wood with the low maintenance advantages of vinyl or aluminum. For instance, you never have to paint or retreat Fibrex® because it is extremely durable, manufactured in intense heat.

Fibrex® is a polymer created from a blend of materials (including wood fibers). The solution is blended with your desired color ahead of time. Fibrex® is so strong that it can endure the heat involved in darkening processes, giving you more options than with other materials.
