Materials 

The durable materials of these clad windows give you two low-maintenance and cost-saving options. Clad windows have a wood frame with an exterior cover such as fiberglass, vinyl, or aluminum.

A-Series 

Interior - Wood

Exterior - Fiberglass and Fibrex

The interior window sash and frames are constructed of solid wood. Fiberglass and Fibrex material are used for the exterior sash. Fibrex is a combination of reclaimed wood fiber and PVC polymer. It’s twice as strong as vinyl, environmentally friendly, and energy-efficient. An annual wash is all these windows need.

400 Series 

Interior - Wood

Exterior - Vinyl

400 Series are vinyl-clad windows. The vinyl exterior protects the frame, resists dents, repels water, and seal out elements. Additionally, Perma-Shield technology used in the exteriors means they’ll never need to be repainted and won’t peel, blister, flake, or corrode.

Construction and Sizes 

Both A-Series and 400 Series windows are available for new and replacement window projects.

A-Series

Double-Hung windows are available up to 4’ wide and 8’ high. Custom sizes are also available in 1/8” increments.

400 Series

Double-Hung windows are available up to 3'10-1/8" wide and 7'8-7/8" high with custom sizes available in 1/8" increments.

Energy Efficiency - Andersen A-Series vs 400 Series

New and well-installed replacement windows should always be more energy efficient than those being replaced, but the glass also affects energy efficiency. In fact, glass can affect energy efficiency more than any other part of a window or patio door.

Not all glass insulates the same. Andersen offers one of the industry’s widest array of glass options, so you’re sure to find the right choice for your climate and your home.

A-Series

The A-Series is Andersen’s best performing energy efficient window. The windows in this series have been recognized by ENERGY STAR as some of the most efficient residential window models available in the U.S. and Canada.

400 Series

Weather-resistant construction means greater comfort and more energy efficiency. These windows, like those in the A-Series, have weather stripping designed to seal out drafts, wind, and water.

Styles - Andersen A-Series vs 400 Series

  

A-Series

Available in four popular styles: awning, casement, double-hung, picture. The A-Series also offers 34 specialty shapes.

400 Series 

This series offers a variety of window options such as awning, casement, double-hung, gliding (sliding), picture. The 400 Series offers 20 specialty shape windows.

Additional customization is available in hardware and hardware finishes, grilles and grille patterns, and interior and exterior window finishes.

Glass and Grilles - Andersen A-Series vs 400 Series

Remember, glass can affect energy efficiency more than any other part of a window. Both the A-Series and 400 Series offer the following options:

• Low-E4
• Low-E4 with Heatlock Coating
• PassiveSun
• SmartSun
• SmartSun with Heatlock Coating
• Sun

The A-Series also offers Triple-Pane glass.

Grilles (or grids) are an aesthetic touch that gives your window a more traditional look. Before technology made creating large panes of glass a possibility, glass for windows was made in small individual pieces that were joined together by window grilles.

Andersen offers 4 grille patterns to match popular architectural styles as well as custom patterns.

Each of the below patterns is available for both the A-Series and 400 Series.

Finelight Grilles Between-the-Glass

• This option places the grilles between the panes making the interior and exterior glass easy to clean. 
  

Full Divided Light

• Grilles are applied to the interior and exterior sides of the window. A divider between the glass creates an illusion of individual panes for an authentic look.
  
  

Removable Interior Grilles

• Grilles are fastened on the interior side of the window making them easy to remove and thoroughly clean the glass.
  
  

 

Simulated Divided Light

• Similar to the Full Divided Light option, grilles are applied on the exterior and interior sides of the window. The interior grille can be removable, or permanent. The exterior grille is permanent. There is no divider between the glass.
  
  

Tilt Sash - Andersen A-Series vs 400 Series

The sash holds the glass that moves up and down when you open the window. On a tilt sash, that part can unlatch from the frame and swing-down. With a tilt sash, you have the option of cleaning the exterior of your window from inside your home.

Tilt sash options are limited to only some of Andersen's window products including Double-Hung windows in the 400 Series and A-Series.
