With over 100 years in the industry Andersen is THE name in windows and they have continued with this excellence with their innovations in the 100 series. The Andersen 100 series is the original composite window made of their proprietary Fibrex material which combines the ease of maintenance of vinyl with the strength of wood. This means a window that is manufactured with less waste while providing a product that is 2x as strong as a vinyl window. Others have had to play catch up as Andersen has paved the way in the composite market with the 100 series. This shows with their varied color options available allowing you to complete the look of your home with a superior product that will outlast the rest.
