History of FIBREX® - Fifty Years In The Making

Innovation has been the hallmark of Andersen Corporation since its founding in 1903. Renewal by Andersen windows are constructed with Fibrex®, Andersen’s most innovative product ever.

Andersen Corporation was founded in 1903 and quickly revolutionized the way windows were installed by pre-cutting materials for carpenters to assemble on the building site. Over the years, Andersen proudly introduced other industry milestones, including new technologies and methods that made windows and doors last longer, look better, and function as intended for many years. By the 1950s, Andersen's research and development efforts were laying the groundwork for Fibrex® material and a brand new way to provide homeowners with beautiful, high quality, and efficient replacement windows.

The History of Innovation, FIBREX^® Throughout The Years:

1958
Aluminum rejected as a framing material due to high conduction of heat and cold.
1959
Andersen is the first company to develop a hollow vinyl window in the U.S. but decides it doesn't have enough structural integrity. But the low-maintenance feature of the vinyl had possibilities.
1966
Andersen creates the "clad-wood" window and door category (still the standard of excellence in stock-size new construction). Andersen Research & Development invents a way to weld the corners together for airtight, watertight performance.
