Fibrex® Material Vs. Vinyl Windows

Fibrex® material is offered exclusively by Renewal by Andersen and combines the best qualities of wooden and vinyl windows for a superior, long-term seal.

This is accomplished through a signature extrusion process, which combines 40% reclaimed wood fiber by weight with composite polymers.

Fibrex® strength also means you can see more of your Maine scenery with narrow but strong frames and wide panes of energy efficient, dual-pane glass.

In any style, our windows remain functional overtime with frames that won’t bend or expand despite years of unpredictable weather and regular use.

Plus, our frames are completely saturated with your chosen color(s) when designed for your exact window opening, so you’ll never experience peeling or cracking paint.

Renewal by Andersen’s exclusive Fibrex® material truly combines only the best features of wood and vinyl. Learn more about personal and global energy savings with our home windows and installation when you contact Renewal by Andersen Portland, ME today.

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.
