Andersen 400 Series Specialty Shape Windows
Arches, circles, eyebrows, trapezoids and more than thirty other shapes — stationary windows that finish a design the way nothing else can.
Made in the USA ENERGY STAR® certified Owner-2-Owner® warranty

Overview
Why choose the 400 Series Specialty Shape Windows?
Looking for a stationary (non-venting) window to complete a gable, top a double-hung or add light to a stairwell? Andersen’s best-selling specialty windows come in a wide array of shapes and sizes, each built with a wood interior frame, a low-maintenance vinyl exterior and the same seven exterior colors as the rest of the 400 Series, so an arch above a picture window matches perfectly. Wood core members provide excellent structural stability and energy efficiency; interior trim is unfinished pine, ready for stain or paint.

Interior Color

Exterior Color
Black and Dark Bronze interiors are available only with the matching exterior. Pine interiors can be ordered unfinished or prefinished white.
Grilles add architectural character and can be matched to the style of your home. Choose the grille construction first, then the pattern.

Full divided light
Grilles on the interior and exterior with an aluminum spacer between the glass for the most authentic look.

Simulated divided light
Permanent exterior grilles with permanent or removable interior wood grilles and no spacer between the panes.

Finelight™ between-the-glass
Grilles sealed between the panes for the easiest cleaning.

Removable interior grille
Interior wood grilles secured with a clip that lift out so you can wipe the glass in seconds.

Every Andersen 400 Series unit can be ordered with the glass package that fits its exposure. All options are ENERGY STAR® certified configurations; ask us about impact-rated glass for coastal wind zones.

SmartSun™ glass
All the benefits of Low-E glass plus extra protection from the Florida sun — it filters out 95% of harmful UV rays while letting daylight through. Our most-recommended glass for North Florida.

Low-E4® glass
Reflects summer heat away and helps hold conditioned air inside, a strong all-around choice where cooling costs matter most.

HeatLock® coating
An interior-surface coating that reflects escaping heat back into the room. Can be added to most Andersen glass options.

PassiveSun® glass
Lets the sun help warm your home in winter — best suited to shaded or north-facing openings.

Dual-pane glass
Clear insulated glass with basic thermal performance, available where local codes allow.

Low-E4® Sun glass
A subtle tint that blocks even more solar heat — ideal for west-facing walls and pool decks.
Decorative & specialty glass
Patterned, obscure and art glass for bathrooms, entries and accent windows, plus tempered safety glass where code requires it.
Stationary specialty windows are built to the exact shape and size of your opening in ⅛" increments — pair them above a double-hung, flank a picture window, or let one stand alone in a gable.


































Interior trim options
- Interior arch casing in Colonial (2¼", 2½" or 3½") or Ranch (2¼" or 2½") profiles — pine, oak or maple.
- Plinth blocks and transition blocks for clean casing transitions on circle and oval units.
- Key block accents at the top of arched casings.
