If you’re looking to replace your old, inefficient windows, you may have seen advertisements for vinyl windows. Vinyl is a popular choice because it is a cheaper material and provides a quick, short-term solution.
But if you want windows that maximize beauty, energy efficiency and durability for decades to come, you should consider Renewal by Andersen replacement windows made from our exclusive Fibrex composite material.
What Is Fibrex?
It takes the right combination of glass, framing material and professional installation to make a strong, long-lasting window. Renewal by Andersen has transformed the window replacement industry with the development of an innovative composite window frame material called Fibrex, which is composed of a combination of wood fibers and thermoplastic polymers with impressive insulating properties.
Stronger Frames for Better Durability & Better Views
Fibrex is twice as strong as vinyl, allowing for sashes and frames to be thinner and narrower, giving you more glass area and a better view. Vinyl frames, on the other hand, tend to be thicker and bulkier, resulting in decreased glass area.
In addition, our windows are low-maintenance and are warranted not to flake, rust, blister, peel, crack, pit or corrode—so you’ll never again have to endure the tedious tasks of scraping and painting.* Built in Minnesota, our windows are proven to stand up to even the harshest midwestern winters. Plus, our windows stand the test of time and are as easy to operate after 20 years as the day they were installed.**
Low Thermal Expansion Rates & High Energy Efficiency
Fibrex has a low expansion rate, meaning it resists expansion and contraction. Vinyl has a much higher expansion rate that can result in bowing and cracks that let in water and allow air to leak out. Windows made of Fibrex are superior to vinyl because no matter how much temperatures fluctuate, they won’t crack or warp. This means we can offer dark exterior colors that aren’t available in vinyl since Fibrex can stand up to intense heat of direct sunlight.
