Fibrex® Material: The #1 Alternative to Vinyl Window Frames
– Our Andersen® exclusive composite material was created to combine only the best qualities of wooden and vinyl window frames.
– They’re made with 40% reclaimed wood fiber by weight and reinforced with polymers to perform with the sturdiness of wood yet durability of vinyl—and then some!
– Fibrex® material is available in a wide variety of colors—including darker colors not usually available for home windows for a rustic look.
– Whatever color(s) you choose, the Fibrex® material extrusion process saturates color throughout your window frames. That means they stand up to even extreme weather and climates without chipping, flaking, or cracking.
– Fibrex® material holds window glass with twice the strength of vinyl for sleek, narrower frames that result in a wider view in any style.

I love my new windows, made a HUGE difference in the drafts, keeping wind noise out, and keeping heat in. I also choose a different style and the view is much nicer, easier to open and close

Tonya B.

We are extremely pleased with our large dining room window. The old window was not efficient; letting cold air into the house in the winter as well letting heat from the furnace outside! The installer was very professional, efficient and cleaned everything up nicely. The entire experience from sales to installers through follow-up was a pleasure.

Seth Y.

Replaced 12 "old" draft double hung windows with new double hung windows. Remarkable improvement in maintaining and constant comfortable temperature in the rooms. Great workmen and a great finished job.

Tangelia N.

We couldn't be happier with all aspects of the process (sales & installation). Everything went very smoothly and I was amazed at how clean my house was at the end. The windows are beautiful and I'm sure we'll see major savings in our heating bills this winter.

Jennifer A.

Excellent service. The install started on the date promised and completed within the indicated time frame. I was pleasantly surprised at how clean the installers left the job site. Everyone I dealt with was extremely professional. When it comes time to replace the French doors, I will be using Renewal by Anderson.

Roger F.

The people, product, and installation surpassed all my expectations. Home is noticeably quieter, cooler in the daytime, and each window has a beautiful view as compared to the old aluminum frame.
