Our replacement windows feature some of the most advanced window technologies available on the market today.
Instead of manufacturing 100% wooden or 100% vinyl windows, Renewal by Andersen uses a material called Fibrex to provide durability, insulation, and energy efficiency to our windows.
Fibrex is a specialized composite made of 60% thermoplastic polymer and 40% reclaimed wood fiber. This reclaimed wood comes from Andersen Corporation’s other manufacturing operations.
Fibrex’s composite construction gives it some distinct advantages over vinyl windows and wooden windows:
Thanks in large part to our use of the environmentally-friendly Fibrex, Andersen Corporation has the honor of being the only Green Seal® certified window manufacturer.
By combining durable Fibrex with High-Performance™ Low-E4™ glass, your windows will save you money for years.
High-Performance™ Low-E4™ glass adds thermal protection to each Renewal by Andersen window, resulting in lower energy bills for most.
In addition, High-Performance™ Low-E4™ glass protects your furniture and flooring from damaging UV rays while greatly reducing sound infiltration into your home.
High-Performance™ Low-E4™ glass also reduces water spots up to 99%. This means you’ll spend less time, money, energy and materials cleaning your windows.
