Energy-Efficient Windows

Energy Savings Through Window Replacement

Renewal by Andersen installs energy-efficient windows that help to reduce home energy consumption and lower monthly heating and cooling bills. Each window produced by Renewal by Andersen utilizes energy-efficient materials that are designed to limit the amount of energy needed to maintain a comfortable and cozy environment in your home. Here’s what makes our windows among the most energy efficient you can buy.

About Fibrex® Window Material

Renewal by Andersen® Fibrex® frame material offers the beauty and strength of wood with the insulation and low maintenance of vinyl. This composite wood offers durability, energy efficiency and sustainability, making Fibrex® some of the best energy-efficient windows available.

Fibrex® material is 60% thermoplastic polymer by weight and 40% wood fiber by weight, reclaimed from our manufacturing processes. These materials are fused to create a composite that provides an excellent alternative to vinyl.

The material hardens when cooled and flexes in heat to adjust to temperature changes. Its unique fabrication process blends the color of the window with the Fibrex® material to ensure the window is beautiful and long-lasting. You can choose many finish options in a wide selection of colors.

The qualities of Fibrex® windows make them one of the best energy-efficient windows:

  • strength in various weather conditions
  • durable to resist rot, warps and chips
  • decay resistance against mold, dirt and stains
  • high heat distortion point to prevent bending and warping
  • low thermal expansion
  • excellent insulating properties
  • high compressive strength
  • environmentally friendly components

Advantages of Installing Fibrex® Windows

Fibrex® windows offer several advantages. This material:

  • Blocks thermal transfer: Fibrex® blocks thermal transfer nearly 700 times better than aluminum and vinyl to help reduce heating and cooling bills.
  • Endures temperature changes: These windows stand up to the heat and cold, so they can be installed in humid, dry, cold or hot climates. The material has low thermal expansion and will not expand or contract very much.
  • Eliminates energy leaks: Fibrex® will not crack, pit, corrode or rot like wood or vinyl, which helps to reduce energy loss.***
  • Uses recycled materials: Fibrex® windows are made with recycled materials from our manufacturing processes. This sustainable material is environmentally conscious.
  • Allows for bigger windows: Fibrex® is twice as strong and durable with higher compressive strength than vinyl, so the window can have narrow frames and support a larger glass area for bigger windows.
  • Beautifies your window: Fibrex® can be formed into many profiles and is available in many wood options and colors to coordinate with your home’s design.
  • Reduces maintenance: Fibrex® is a low-maintenance option. The material won’t fade, flake, blister or peel over time.

Glass Options for Energy-Efficient Windows

Renewal by Andersen® windows utilize two distinct energy-saving glass packages with low-emissive (Low-E) glass. Glass options include:

  • High Performance™ Low-E4®: Low-E4® glass offers energy performance and comfort to reflect heat in the summer and keep heat in the winter. This glass is 45% more energy efficient in summer and 56% more energy efficient in winter as compared to ordinary dual panel glass.***
  • High Performance™ Low-E4® SmartSun™: SmartSun™ glass offers the benefits of Low-E4 glass in addition to ultraviolet (UV) ray protection. The glass is designed to filter out 95% of UV rays and the sun’s heat. This glass is 70% more energy efficient in summer and 45% more energy efficient in winter as compared to ordinary dual-panel glass.***

Custom Sizing on Every Window

Even the most advanced window materials will not work at peak energy efficiency if not properly installed. That is why Renewal by Andersen custom fits each window for the home in which it is to be installed. The custom fit ensures a durable, weather-tight seal that prevents energy leaks.
