Fibrex® window frames are a Renewal by Andersen exclusive. Made with a proprietary blend of polymers and reclaimed wood fiber, Fibrex® windows combine only the best qualities of wooden and vinyl windows all-in-one!
In addition to long-term performance, Fibrex® offers:
- A weatherproof seal. In any weather and throughout all North Carolina seasons, Fibrex® protects your interiors from heat, excessive sunlight, drafts, moisture, and any other outside elements. Even in functional styles, our windows are guaranteed to save money on heating and cooling costs—up to 72% in summer!
- Custom shape and style. Fibrex® material is created with an extrusion process, during which manufacturers can permanently mold your window to fit nearly any imaginable shape and size. Plus, your chosen interior and exterior color is completely saturated into the frames to eliminate flaking, cracking, peeling, or bending.
- Clear, wide views. Fibrex® holds windowpanes with twice the strength of vinyl, which means any style features narrower frames and the largest possible view of your natural scenery.
- Functional windows are backed by a 20-year guarantee to not expand, stick, or otherwise become more difficult to open over time.

With a narrow frame that allows for more glass area and light to enter your home, Renewal by Andersen windows can help you experience the best views of the outdoors and look great doing it. Renewal by Andersen windows & patio doors can be completely customized to complement your unique style along with the current look and feel of your home. During your window design consultation, our experts will walk you through the following replacement window design options:


- Sleek, modern frames. Even in classic functional styles, Renewal by Andersen windows feature thin frames and a wider field of vision to bring more light and scenery into your home.
- Custom window styles. The extrusion process allows us to craft your windows to any shape—meaning you can match the architectural style of your home…or define a new look.
- Colors to match any home. The same process infuses color into the core of Fibrex® material, offering you a wide palette of long-lasting colors to choose from—including dark exterior colors not found with most other replacement windows.
- Stainable interiors. We also offer contrasting wood interiors including oak, maple, and pine, so you can match or recreate a vintage architectural style.
- A wide range of hardware, accessories, and grilles. Choose from a variety of styles in window and door hardware plus multiple types of window grilles to match or update your home.
