Andersen Helps Conserve Natural Resources Through Increased Use of Fibrex® Material

Andersen%20WindowAndersen Corporation, a durable goods manufacturer for over one hundred years and the leading brand of windows and doors, continues its commitment to environmental efforts through increased use of Fibrex® material. Fibrex material is the company’s patented, highly sustainable structural composite that blends the best attributes of thermoplastics and bio-fibers – much of it reclaimed directly from the company’s manufacturing plant operations.

Andersen began producing windows made from wood in 1903, and in 1966 introduced vinyl cladding to help reduce maintenance and increase durability. After decades of experience with these two materials, the company introduced Fibrex® material in 1994. It combines the strength and stability of wood with the low-maintenance features of vinyl.

Fibrex material not only reduces the company’s need for raw timber, but reclaims much of its wood wastestream, as well. It provides an efficient use of embodied energy in the reclaimed wood fiber and helps reduce volatile organic compound emissions, since no wood preservative treatment or painting is required. Additionally, converted Fibrex material can be reclaimed and reprocessed into new components. Andersen has saved hundreds of thousands of board feet of lumber since its introduction.

Wood is an important and renewable material that we’ve used in our products for more than 100 years,” said Shawn Aherns, product marketing manager at Andersen. “Combined with our preference to certified wood supplies, Fibrex material allows us to conserve natural resources and strive for continuous improvement of our environmental performance.”

Andersen uses Fibrex® material in the construction of many of its products including its Woodwright® double-hung windows, Renewal by Andersen® replacement windows, 200 Series basement windows and sill components for windows and patio doors.

Independent testing has found that the material has a low thermal expansion and contraction rate, is resistant to rotting and termites, and retains its rigidity and stability in high temperatures.

The design flexibility of Fibrex material allows us to research exciting product possibilities and applications,” said Aherns.

The Andersen® brand is the most recognized and most used brand in the window and patio door industry. For a local dealer, more information or a copy of the Andersen limited warranty, visit, or call 1-800-426-4261.
