When Andersen scientists first conceptualized composite window technology in the 60s, longevity was the biggest priority. Perfected in 1992, Fibrex® was invented to deliver the structural superiority of wood with the low-maintenance benefits of vinyl, resulting in a material that offers unparalleled longevity.
Don’t just take our word for it though. We concluded our first, long-term durability study in Minnesota in 2015, in which we looked at how Fibrex double hung windows had held up after enduring 20 years of Minnesota’s brutal winters and muggy summers. The results speak for themselves.
After 20 years of ongoing use and constant exposure to harsh elements, Fibrex had maintained its weathertight seal. This is the opposite of what happens to many vinyl products that bow and crack due to extreme conditions. Thanks to its low expansion and contraction rate, Fibrex is 200% stronger than vinyl and guaranteed to prevent leakage for a longer period.
Because of Fibrex, our casement, picture, bay, bow, specialty and sliding windows look like they’re made from wood. Unlike wood, however, they’re resistant to decay. Part wood fiber, part polymer, Fibrex has the remarkable ability to expel moisture and hold its desired finish for a lifetime. As per ASTM E2068, our study reveals that our Fibrex-made units had no signs of peeling or chipping 20 years after installation.
Unlike other frame materials that expand or contract due to temperature fluctuations, Fibrex remains stable. This has enabled it to deliver smooth operation for 20 years in Minnesota. After withstanding real-world challenges, our confidence in our products has reached new heights, which is reflected in our stellar warranties. The powerful warranty coverage of our replacement windows protects against defects in manufacturing, materials and workmanship. We’ll return to fix the problem or recreate the units if necessary.
