When it comes to innovations in window replacement, Renewal by Andersen® has set itself apart from the competition. Our parent company, Andersen Corporation, introduced Fibrex®, a composite material made from wood fibers and polymer. Ever since it was patented in 1991, Fibrex changed the way people perceive windows. In this video, learn how our Fibrex frame material helps make our windows strong, durable and energy-efficient.
How Fibrex Is Made
Fibrex is composed of 40% wood fiber by weight and 60% proprietary polymer. The wood used to make the composite material is repurposed, meaning it is left over from Andersen’s manufacture of wood windows.
To make Fibrex, the wood fiber is first heated to remove all moisture until dried. The polymer is then liquefied through heat at a specific temperature. As the two materials are combined, they begin bonding together at the molecular level. During the process, the liquid polymer is pressurized to encase every cell of the wood fiber and then the individual wood fibers begin binding together. This forms a tough material engineered to be twice as strong and durable as vinyl.
What Fibrex Brings to Your New Windows
Because of the alignment of Fibrex’s wood fibers with the polymer, your new casement, sliding or double-hung windows will have the remarkable ability to repel moisture. In addition, the material’s durability ensures that your windows won’t rot, fade, flake, peel or blister, even at extreme temperatures. Fibrex is extremely low maintenance, so painting is not required.
Indeed, the stability and rigidity of Fibrex is the reason why our windows are the best choice for any weather and any season. With Fibrex windows, you get the strength of wood and the low maintenance of vinyl.
