Andersen 100 Series vs A Series - Replacement Windows Review

Not all windows are the same but the difference is sometimes hard to understand when comparing two similar options. In this article, we’re comparing two Andersen window series that will give you an idea of what you can get from opposite ends of the cost spectrum.

Materials 

100 Series

• Fibrex® composite

Products in the 100 Series are made of a composite material Andersen calls Fibrex. Fibrex is made of a combination of reclaimed wood fiber and PVC polymer. It is twice as strong as vinyl, energy efficient, and environmentally friendly.

It is environmentally friendly because it is made of recycled materials. By reusing wood and PVC fibers Andersen is keeping materials that carry adhesives, paint, primer, and other contaminants out of landfills and incinerators.

Maintenance for windows made of this material is very low. A regular cleaning and an annual wash to remove any accumulated debris are all these windows need.

A-Series

• Wood interior with Fibrex and fiberglass exteriors

A-Series windows are wood clad windows with Fibrex and fiberglass composite exterior. Wood windows have a unique beauty to them that can’t be matched by vinyl or aluminum materials but each of these materials has their positive and negative aspects.

Wood, for instance, is susceptible to insects, rot, and warping that’s why so many manufacturers offer cladded windows. Clad is a covering that protects another surface. The A-Series is a clad wood window protected by a Fibrex and fiberglass exterior.

The interior of the A-Series windows will eventually require more upkeep but for the first few years after installation, they’ll just require a regular cleaning. The exterior of the windows are more low-maintenance than the interior and should remain so until they reach the end of their lifespan. Like the 100 Series, the exterior of these windows should be washed annually to remove any accumulated debris and to inspect for any irregularities either in or around the window.

Construction  

Andersen 100 Series and A-Series windows are available for both new construction and replacement projects.

Sizes

100 Series

Standard sizes for double-hung windows are up to 4’ wide and 7’6” high with custom sizes available in 1/8” increments

A-Series

Standard sizes for double-hung windows are up to 4’ wide and 8’ high with custom sizes available in 1/8” increments.

Energy Efficiency

100 Series

Products in the 100 Series are able to meet ENERGY STAR® certifications with the right glass package and a proper installation.

The 100 Series is made of Fibrex material which is an excellent insulator and has far better thermal performance than aluminum. It is also thermally on par with a product like vinyl. 

A-Series

The A-Series is Andersen’s best performing energy efficient window. ENERGY STAR® recognizes A-Series windows as some of the most efficient residential window models available in the U.S. and Canada.

Wood has better thermal performance than Fibrex, fiberglass, and vinyl, however, it is the glass that makes the biggest difference in energy efficiency. We’ll go over glass options further into this article.

Styles

There are several style options available for both of these series but you’ll find more options available in the 100 Series. If you’re leaning toward the A-Series for a wood window but see a style available for the 100 Series that isn’t available for the A-Series you’ll want to look into Andersen’s 400 Series or E-Series, two additional wood window options.

100 Series

Awning + Bay or Bow + Casement + Picture + Single-hung + Gliding (sliding) 

A-Series

Awning + Casement + Double-hung + Picture

Grilles

Grilles, or grids, are intended to give your windows are more classic look. Grilles are available for both series in patterns that will complement nearly any style of home. Andersen also offers grille patterns to match popular architectural styles and custom patterns for windows in the A-Series. 

In addition to several pattern options there are four types of grilles available:

Full Divided Light

• 100 Series
• A-Series
• They give your window the most authentic look with grilles on the exterior and interior sides of the window as well as an aluminum spacer between the sheets of glass. The spacer creates the illusion that there are individual panes of glass instead of one sheet. 
  

Simulated Divided Light

• 100 Series
• A-Series
• This option is similar to the Full Divided Light as it has grilles on the exterior and interior sides of the window. The exterior grille is permanent and the interior grilles can be permanent or removable. There is no divider between the glass in this option.
  

Finelight Grilles Between-the-Glass

• 100 Series
• A-Series
• This option places the grilles between the panes of glass making it easy to clean the exterior and interior sides of the window glass.
  

Removable Interior Grille

• A-Series
• This grille is secured on the interior side of the window so you can remove it when you want to clean your full window.
  

Glass

Glass makes has the biggest impact on the energy efficiency of your window so it’s important to choose carefully in order to maximize your energy savings.

100 Series

SmartSun + SmartSun with HeatLock Coating + Low-E + Low-E with Heatlock Coating + Clear Dual-Pane

Tilt Sash

Andersen offers an “Easy Tilt-to-Clean” feature on some of its double-hung windows. The tilt sash can unlatch from the frame and swing-down so that cleaning with window glass doesn’t involve having to go outside. 

This feature is not available in the 100 Series but it is available in the A-Series.
