Our team of experts can offer a free consultation to help you match the right Andersen replacement windows for your needs. Here is a quick comparison between some of the most popular Andersen Windows available in Brookfield, CT.

Andersen 100 Series replacement windows

The Andersen 100 Series is an outstanding choice for Brookfield homeowners seeking a budget-conscious yet durable alternative to standard vinyl windows. This entire series is constructed from Fibrex® composite material, which is Andersen’s proprietary blend of reclaimed wood fiber and thermoplastic polymer. Fibrex® is exceptionally strong—twice as strong as vinyl—and resists fading, blistering, and flaking, which is ideal for the varying climates of New England. The 100 Series offers excellent energy efficiency and a low-maintenance exterior with a clean, modern aesthetic. While the color and style options are more limited than the premium lines, the 100 Series provides a high-quality, long-lasting, and cost-effective solution for Andersen replacement windows in Brookfield, CT.

Andersen 400 Series replacement windows

For a blend of performance, style, and long-standing trust, the Andersen 400 Series remains the most popular choice among contractors and homeowners alike. This series features a traditional wood interior protected by a tough, low-maintenance vinyl exterior cladding (Perma-Shield®). The 400 Series is renowned for its weather-resistant construction and high energy efficiency, which makes it a reliable performer in the cold Connecticut winters. This option offers a broader selection of colors, hardware, and grille patterns than those available in the 100 Series, along with a comprehensive array of window styles. In short, for Brookfield homeowners, the 400 Series is a versatile option for the wide variety of home styles in need of durable Andersen replacement windows.

Andersen A-Series Replacement Windows

Part of Andersen’s Architectural Collection, the A-Series is their best-performing and most energy-efficient window line, having been crafted with authentic architectural style in mind. This series combines wood interiors with durable, weather-resistant exteriors made from a combination of fiberglass and Fibrex® composite. Homeowners prioritizing maximum energy performance—which can lead to lower heating costs in Brookfield—will find the A-Series appealing, as it is often available with superior glass options, including triple-pane. This is the premier choice for Brookfield homeowners who are seeking a historically accurate or architecturally detailed window with exceptional quality.

Andersen E-Series Replacement Windows

The Andersen E-Series represents top-of-the-line customization and design flexibility within the Andersen lineup. It is specifically tailored for homeowners who are undertaking high-end renovations or those in need of unique design solutions—both of which often command the highest price point. E-Series windows feature a wood interior protected by a durable, extruded aluminum exterior cladding. Their biggest advantage is a vast array of options, which include a massive selection of custom exterior colors, interior woods, finishes, and the ability to accommodate dramatic shapes and sizes. For homeowners seeking a truly unique, highly customized window with a robust aluminum exterior, the E-Series offers design freedom that is unmatched by other lines when considering Andersen replacement windows in Brookfield, CT.

Energy Performance That Lowers Bills

Every choice available at Andersen Windows offers strong performance with official Energy Star certification. Choosing  energy-efficient windows can save you 10%-15% on your home heating and cooling costs each year—if you understand how to pick the proper Low-E glass options based on Solar Heat Gain and U-Factor ratings! 

While all Andersen Windows are ENERGY STAR Certified, some options—such as the Andersen A-Series—offer triple pane glass, which further improves energy efficiency with a U-factor of .23-.28. In contrast, the Andersen 100 Series has a U-factor of .29-.35. (The lower the U-factor, the better.) This difference can be massive, especially during the cold winters of Brookfield. A .23 vs. .30 U-factor has approximately 23% higher energy efficiency. In colder climates, the additional heat loss can be noticeable, especially considering the long-term investment of your windows, which may last 20 years or more.

When you purchase Andersen replacement windows, you know that you are getting the best in energy efficiency and reliability, as they offer superior comfort and strong thermal protection.

What Affects Cost?

The cost of new replacement windows in Brookfield will vary, based on the materials used, complexity of the installation, and the quality of factors, such as energy efficiency. Ordering custom window shapes or designs can mean additional costs as well. 

The design and function of the windows you choose have a major impact on cost.

  • Window Type: Standard styles (like double-hung windows and sliding windows) are generally more affordable than specialized options (like bay windows, bow windows, or casement windows).
  • Size and Shape: Standard, common sizes cost less than custom-sized windows or unique architectural shapes—like arches or circles, which require specialized manufacturing.
  • Grids and Hardware: Aesthetic upgrades—such as decorative grids (grilles) or premium hardware finishes—will increase the material price.

The material of your window frame affects its durability, energy efficiency, maintenance, and—most importantly—its price.

  • Vinyl Windows: Often the most cost-effective choice, offering good energy performance and requiring minimal maintenance.
  • Fiberglass Windows: A mid-to-high-range option, known for exceptional strength, durability, and resistance to temperature changes.
  • Wood Windows: Typically the most expensive option, providing classic beauty and excellent insulation but requiring more maintenance.
  • Composite Windows: Materials that blend the strength of wood with the low-maintenance benefits of vinyl.

Investing in highly energy-efficient windows may increase your initial investment but lead to significant long-term savings on energy bills.

  • Number of Panes: Double-pane windows are standard, but triple-pane glass offers superior insulation, making it a premium (and higher cost) upgrade.
  • Low-E Coatings: Low-emissivity (Low-E) coatings reflect heat and UV rays, significantly boosting efficiency but adding to the price.
  • Inert Gas Fills: Filling the space between glass panes with non-toxic gases like Argon or Krypton improves thermal performance and adds to the cost.
