What is Fibrex®?

  • Composition: Fibrex® is a composite material made from a blend of wood fiber, mostly reclaimed from Andersen Corporation’s wood window manufacturing process, and thermoplastic polymer, some of which is also reclaimed.
  • Development: Developed by Andersen Corporation, it was created to combine the strength and rigidity of wood with the low-maintenance features of vinyl.

Energy Efficiency of Fibrex® Windows

  1. Thermal Insulation: Fibrex® has excellent insulative properties. It reduces thermal transfer significantly more efficiently than aluminum, helping to keep homes warmer in winter and cooler in summer.
  2. Durability: The material does not warp, rot, or corrode – issues that can lead to energy loss in traditional window frames.
  3. Low Expansion and Contraction: Fibrex® has a very low rate of expansion and contraction, which means the window seals remain tight and intact over time, preventing air leaks and energy loss.

Environmental Benefits

  • Sustainable Manufacturing: The use of reclaimed materials in creating Fibrex® reduces waste and the environmental impact associated with producing new raw materials.
  • Longevity: The durability of Fibrex® means the windows have a longer lifespan, reducing the need for frequent replacements and the associated environmental impact.

Cost Savings

  • Reduced Energy Bills: By improving the thermal efficiency of homes, Fibrex® windows can lead to significant savings on heating and cooling bills.
  • Maintenance Costs: The material’s resistance to rot and decay translates to lower maintenance costs over the lifespan of the window.

Aesthetic and Functional Advantages

  • Design Flexibility: Fibrex® can be manufactured in a variety of shapes and sizes, allowing for customization in window designs.
  • Color Retention: The material retains its color longer than vinyl, reducing the need for repainting and contributing to the overall aesthetic appeal of the property.

Conclusion: Fibrex® material offers a compelling combination of energy efficiency, durability, and environmental sustainability, making it an excellent choice for window construction. For homeowners looking to enhance their property’s energy performance and reduce their carbon footprint, windows made with Fibrex® material present a promising solution. While the initial investment might be higher compared to conventional materials, the long-term savings and benefits make it a worthwhile consideration.
