Video: How Fibrex® Stands the Test of Time

One of the reasons discerning homeowners gravitate toward Renewal by Andersen® of San Francisco is Fibrex®. Perfected in 1992 by Andersen, our patented, wood-polymer composite is the superior alternative to traditional window materials.

To outfit your home with windows that stand the test of time, there’s no better choice than Fibrex. Here’s why:

Built to Stand Up to the Elements

Fibrex is made from 40% reclaimed wood fiber by weight, giving it the remarkable strength, stability, and rigidity of old-fashioned timber. As a result, Fibrex is 200% stronger than vinyl. It hardly expands or contracts with extreme changes in temperature, allowing it to retain its weathertightness for decades in all climates. It would also prevent unwanted drafts from coming into your home.

Unlike inferior products, Fibrex takes the heat well. We use an advanced extrusion process to fuse our finishes to it excellently. In turn, its factory-applied exterior finish resists fading. This is why we’re able to offer long-lasting, dark window colors.

Proven to Last by Science

To put Fibrex’s resilience to test, we conducted our first long-term durability study recently. We removed 10 perfectly good windows from one of our first customers to see if Fibrex remains structurally sound. After 20 years of Minnesota’s brutal winters and muggy summers, onsite and lab tests revealed that Fibrex shows no signs of chipping, peeling, and cracking. Fibrex-made windows were still as easy to open and close as when they were first installed.

Guaranteed to Perform a Long Time

We provide extensive coverage on our Fibrex components. We warrant them not to rust, rot, corrode, flake, blister, pit, peel, or crack for 20 years from their original installation date. For the same period, we guarantee our Fibrex-made windows to be free from defects in manufacturing, material, and workmanship. Furthermore, its exterior color finish comes with a 10-year warranty, which is almost unheard of in the window industry.
