Andersen 400 Series Casement Windows
A single sash that swings outward for top-to-bottom ventilation and a clean, unobstructed view when closed — Andersen’s best-selling casement.
Made in the USA ENERGY STAR® certified Owner-2-Owner® warranty
Overview
Why choose the 400 Series Casement Windows?
Casement windows are the most efficient venting window you can buy: the whole sash opens, and because it closes against the frame like a door, the seal is exceptionally tight. The Andersen 400 Series casement offers a wide array of options and accessories, from eleven hardware finishes to seven exterior colors and a full range of grille patterns, so you can customize the window to your home’s design. A single-actuation lock releases every locking point with one motion.

Grille patterns
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.
Every window includes an insect screen; upgrade to TruScene® for a nearly invisible view.
Conventional insect screen
Charcoal powder-coated aluminum mesh in a frame available in White or Stone. Sits on the interior so it stays clean and out of the weather.
TruScene® insect screen
Andersen’s exclusive TruScene® screens provide over 50% more clarity than conventional screens, let in more light and air, and keep out smaller insects.
Exterior trim
Factory-applied exterior trim completes the look and is often essential for authentic architectural style. Match your window color or choose a contrasting trim.
