Fibrex® Delivers Value: What Puts RbA Products on Top?

For your window replacement, choosing a material that is built to last is the wisest choice. Renewal by Andersen® revolutionizes the window replacement industry by providing an innovative frame material that is both sophisticated and robust. Fibrex® is a prime window material on the market that is known for its durability.

What is Fibrex?

Made from polymer and wood, it offers the classic look of wood and the low-maintenance qualities of vinyl. Let us take a closer look at its composition:

  • Eco-friendly composition: 40% wood fiber by weight, 60% thermoplastic polymer by weight, some of which is reclaimed.
  • Fibrex blocks thermal transfer better than metal and aluminum. This helps in reducing space heating and cooling.
  • Since no repainting and wood preservative treatment is needed, VOC (volatile organic compounds) emissions are reduced.
  • Proven to be twice as strong as vinyl; weather-tight seals stay fitted for improved energy efficiency.
  • It is tested to retain rigidity and stability in varying weather conditions and in all climates.
  • Renewal by Andersen’s exclusive process blends the color well with the material during frame production for a guaranteed long-lasting beauty.

What makes Fibrex a cut above the rest?


Fibrex has intensive thermal insulating properties. Combined with High-Performance™ Low-E4® glass, it helps your home cooler in summer and warmer in winter.


Fibrex frame reflects lines and shape of your original windows. Most replacement windows on the market feature a square shape that looks artificial. Vinyl, which is a popular frame material is often thicker that reduces the glass area.


Fibrex is backed up by a 20/2/10 Limited Warranty, which is one of the most competitive in the window industry.
