Renewal by Andersen Fibrex® Frames vs. Vinyl
Fibrex® material is made with 40% recycled wood fiber to combine the most energy efficient qualities of both vinyl and wooden windows.
Windows can be molded to nearly any shape during the extrusion process, and maintain shape for years to come without bowing or bending.
You can also choose nearly any combination of interior and exterior colors. Color is completely saturated into Fibrex® frames to prevent chipping, so you can enjoy vibrant color for years to come.
Our windows are strong enough to hold large panes of glass with narrower frames, so you can experience a great view without risk of decomposition.
Renewal by Andersen windows are defined by unmatched energy efficiency. In any style, and in any climate, they’re guaranteed to reduce heating and cooling costs for your home.

Renewal by Andersen’s Fibrex® composite material is better than any old vinyl or wood window on the market, we can guarantee that. More than anything, while the seasons may change, we are committed to standing by our window replacement product, today, tomorrow, and well into the future.

Testimonials

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.
