What Are Andersen 100 Series Windows?

Andersen 100 Series windows are a line of windows produced by Andersen Corporation, a renowned name in the window and door industry. These windows are known for their composite material, which boasts durability and eco-friendliness.

Why Consider Andersen 100 Series?

  • Eco-Friendliness: Andersen’s Fibrex® material is environmentally responsible.
  • Durability: Resistant to fading, chipping, and peeling.
  • Variety: Available in a range of styles and colors.

Exploring the Features of Andersen 100 Series Windows

Material and Construction

Fibrex® Technology: At the heart of the Andersen 100 Series is the revolutionary Fibrex® composite material. This proprietary technology combines the strength and stability of wood with the low-maintenance features of vinyl.

What sets Fibrex® apart is its unique composition – it’s made up of 40% reclaimed wood fiber, mostly sourced from Andersen’s own wood window manufacturing process, and 60% thermoplastic polymer. This blend not only ensures longevity and durability but also contributes to the windows’ environmental sustainability. Fibrex® is twice as strong as vinyl, allowing for narrower frames and more glass area, providing a better view and more natural light.

Design and Aesthetic Appeal

Customization Options: The Andersen 100 Series offers a plethora of design choices, making these windows a versatile option for various architectural styles. Homeowners can choose from a wide range of rich, dark, exterior colors that are not typically available in vinyl windows. The color is fused into the Fibrex® material, ensuring it won’t fade, chip, or peel. Several interior color options are available to match or complement your home’s décor.

The series also offers multiple grille patterns, including traditional and prairie styles, and various hardware finishes, allowing homeowners to tailor the windows to their exact aesthetic preferences. These customizable options make the 100 Series an ideal choice for both new construction and home renovation projects.

Energy Efficiency

Energy Star Rated: Andersen 100 Series windows are not just about good looks; they also excel in energy efficiency. These windows are Energy Star certified in all climatic zones, which means they meet strict energy efficiency performance criteria set by the U.S. Environmental Protection Agency. By choosing these windows, homeowners can reduce their heating and cooling costs.

The windows’ efficient design includes weather-resistant construction that minimizes drafts and heat loss, along with options for Low-E glass that can further enhance energy savings. This makes them an excellent choice for those looking to make their homes more environmentally friendly and reduce their carbon footprint.

Pros and Cons of Andersen 100 Series Windows


  1. Sustainability: The Andersen 100 Series windows stand out for their sustainable construction. Using 40% reclaimed wood fiber in Fibrex® material not only minimizes waste but also reduces the demand for virgin wood and plastic. This eco-friendly approach is in line with contemporary environmental concerns and appeals to the growing market of environmentally conscious consumers.
  2. Low Maintenance: These windows require minimal maintenance, thanks to the durability and weather-resistant properties of Fibrex®. Unlike traditional wood windows, they do not require painting or staining to maintain their appearance and structural integrity. This makes them a practical choice for homeowners who prefer spending less time and resources on upkeep.
  3. Affordability: Compared to other high-end options in Andersen’s lineup, such as the 400 Series, the 100 Series is more budget-friendly. This affordability makes high-quality, durable, and stylish windows accessible to a broader range of homeowners.


  1. Limited Premium Options: While the 100 Series is known for its durability and aesthetic flexibility, it may fall short for those seeking ultra-luxurious features or customizations available in higher-end models like the Andersen Architectural Collection.
  2. Availability: The Andersen 100 Series might not be as readily available as some other popular brands. This limited availability could lead to longer wait times for certain styles or customization options, potentially posing a challenge for tight construction or renovation schedules.
