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 is crafted from reclaimed wood and polymers, can help reduce heating and cooling costs, and reduces VOC emissions – all of which helps keep your energy costs down so you can live little bit greener and a lot more energy efficient.
Our revolutionary Fibrex® windows will hold their shape without bowing, bending, or warping

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.

Best company and customer service that I have worked with. From the sales representative to the installers to the customer people. It was a very positive experience and would tell everyone to use them.

Renewal by Andersen Customer

The windows are beyond my expectation. My dog is even less upset when there is a storm. HE feels safer and so do I. The windows have made a huge difference in the temperature in my house. My house is warmer and I am using less heat. I also love the look of the windows. My house just had a great facelift. I couldn't be happier.

Renewal by Andersen Customer

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.

Renewal by Andersen Customer

We are very pleased with the quality and value of the windows. They are a huge improvement from the existing windows.
