Renewal by Andersen Fibrex Window Frames vs. Vinyl

Renewal by Andersen’s Fibrex® composite material combines the strength and durability of wood with the low maintenance qualities of vinyl, and won’t cause cracks in the joints from the freeze/thaw cycle

With a wide selection of color combinations and palettes, you can expect that there will be no yellowing, bleaching, or fading in the sun, even a decade after your window installation

Fibrex® material’s strength and durability makes for narrower frames. Narrower frames make for more glass in your window and less material obstructing your view of the outdoors

Fibrex® material has superior thermal insulating properties and when combined with Anderson® High-Performance™ Low-E4® glasses, it can help you save money on energy bills.

Our revolutionary Fibrex® windows will hold their shape without bowing, bending, or warping

Renewal by Andersen’s exclusive Fibrex® material is more durable and energy efficient than both wood or vinyl windows, 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.
