The Many Advantages of Fibrex® Window Frames

Fibrex® is a proprietary composite material from Renewal by Andersen®. It is so revolutionary that the company backs it with some of the most extensive warranties on the market today. But what sets it apart from other window materials, like wood, vinyl, aluminum and fiberglass? What makes it a smart investment for any homeowner looking to install new windows? Local windows company Renewal by Andersen of Atlanta shares some of its notable advantages.

Floor-to-ceiling windows

Durability and Reliability

Fibrex is made from a mix of reclaimed wood fibers and thermoplastic polymers, resulting in a composite material that combines the natural strength of wood and the thermal properties of vinyl. Unlike wood, however, it won’t rot, blister, flake or rot. Unlike vinyl, it won’t bow or crack when exposed to extreme temperatures.

Resistance to Moisture and Insects

Fibrex is partly plastic, which means it can keep moisture from seeping through the material in much the same way vinyl would. It also doesn’t corrode like aluminum frames do or rot and decay like wood frames do when exposed to water. Insects cannot make their home in Fibrex.


Fibrex has a stability few window frame materials are capable of. Because of this, we can construct replacement windows using less material. Sleeker frames mean more glass to let sunlight in and provide uninterrupted outdoor views without sacrificing the windows’ structural integrity. Fibrex also doesn’t fade because the color is embedded into the material during the manufacturing process. This eliminates the need for regular painting, staining or scraping usually necessary in wood windows.

Insulating Properties

Fibrex also boasts insulating properties, with a level of resistance to transfer in between wood and vinyl.  Together with low-emissivity (low-E) glass packages, your windows can help keep your home cool in the summer and warm in the winter.
