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.
