The Wonder of Fibrex®: Durability Meets Energy Efficiency

An innovative window material called Fibrex® is getting all the approval for combining the durability of vinyl and the strength of wood. Perfected and patented in 1992 by Renewal by Andersen®, Fibrex® gives homeowners more reasons to replace old windows and benefit from the company’s technology.

Are you tired of your old residential windows in Independence MO? Replace them with Fibrex® and obtain these benefits:


The real wood fiber composites in Fibrex® make it a strong material. Compared to vinyl, it offers narrower frames, giving you more glass area for your windows. Fibrex® doesn’t contract or expand, which other materials are quite susceptible to. Furthermore, it won’t bow and break your glass seal. With Fibrex®, you can be confident that your window’s texture and design won’t chip, fade, or warp. Indeed, the product’s durability and strength goes beyond its structural features.


True to how Renewal by Andersen® fashioned this product (about 40% of its raw materials is reclaimed wood fiber, which can be reground and reused), Fibrex® windows have met environmental certification standards and Energy Star qualifications.

If you want to do your share in preserving the environment and cost-effectively manage your energy consumption, this type of window is recommended. In addition, Fibrex® comes with impressive insulating features to keep your home cool during summer and warm during winter, and to help reduce your cooling and heating costs.


Unlike other types of replacement windows that are only limited to square profiles, Renewal by Andersen® can fit the frame and sash design to match the profiles of your original windows. The company can make Fibrex® into any kind of window, such as curved windows, specialty frames, and double hung windows in Independence MO.

With many options to choose from, getting replacement windows isn’t as easy as it seems. Fortunately, our expert contractors at Renewal by Andersen® of Kansas City can help you make informed choices. We are your product specialist and we are ready to provide more information on Fibrex® windows.
