Why You Should Choose Our Exclusive Window Products

At Renewal by Andersen® of Portland, our window frames are exclusively made from Fibrex®, a durable composite combining the strength and stability of wood with the low-maintenance features of vinyl. Here’s what you can expect from our exclusive window replacement products:

Unparalleled Beauty and Performance

With the exceptional thermal insulating properties of our Fibrex frame material, your home will stay cooler during the summer and warmer during the winter. This helps decrease your energy consumption and lower your energy bills. Our glass options also offer unique benefits for heating, cooling, visible light transfer and UV reduction. 

Thanks to the inherent strenght of our innovative Fibrex frame material, we can manufacture our replacement windows with narrow frames, allowing for larger glass panes and a better view of the outdoors. Our extrusion process also allows us to craft windows into any shape, allowing for almost infinite possibilities. The process also fuses the color into the material, resulting in a wide palette of long-lasting colors, even dark exterior colors not available with most other replacement windows.

Durable and Low Maintenance

Our Fibrex windows are twice as strong as vinyl, and the seals remain weathertight even under the most extreme temperature swings. With our limited warranty, you can be confident that your Renewal by Andersen windows will look just as beautiful and operate just as well after 20 years, provided that they’re regularly maintained and taken care of. We guarantee that our windows won’t rust, flake, blister, crack, peel or corrode.
