Casement Windows
Hinged on the side and cranked outward, casements close against the frame when locked, which can help limit air leakage.
How casement windows work
A casement window is hinged on one side and swings outward like a door, and you can choose left- or right-hinged operation. Casements are commonly opened with a crank handle at the bottom of the frame, so you can open and close the sash without lifting or sliding it. When the sash is closed and locked, it presses against the weatherstripping around the frame, which can help limit drafts. Available hardware and configurations depend on the window system selected for your home.

Why Choose Casement Replacement Windows?
Full-Height Ventilation
The entire sash swings open, and an open sash can help catch a side breeze and direct it into the room.
Easy to Reach
A crank is easier to operate than lifting a sash when you are leaning over a kitchen sink, counter, or deep sill.
Clear, Open Views
With no meeting rail across the middle, casements offer an uninterrupted pane — a natural partner to a picture window.
Closes Against the Frame
Locking pulls the sash against its weatherstripping. Overall efficiency still depends on the glass, frame, and installation.
Energy efficiency, care, and trade-offs
Casement windows can perform well when paired with an insulated glass package and a quality installation, but no window style is energy efficient on its own. Because the sash swings outward, casements are best placed where they will not open into a walkway, deck, or patio. Very wide openings may exceed what a single hinged sash can handle; in those cases, we often pair casements with a picture window.
Specific frame and glass features vary by manufacturer and product line. WeatherMax windows include a Lifetime Accidental Glass Breakage Warranty, a Double Lifetime Manufacturer Warranty, and American Remodeling's 1-Year Workmanship Warranty. All coverage is subject to the applicable written warranty terms, exclusions, and transfer requirements. Read the complete window warranty terms.

Casement Windows questions
Casement windows are hinged on one side and open outward, and you can choose left- or right-hinged operation. They are commonly operated with a crank handle at the bottom of the frame, and a lock secures the sash once it is closed. Available hardware and configurations depend on the window system selected for your home.
They are a popular choice above kitchen sinks and counters, behind furniture, and in other spots where lifting a sash is awkward. Because the sash swings outward, avoid placing casements where they would open into a walkway, deck, or patio.
Not automatically. When closed and locked, a casement sash presses against its weatherstripping, which can help limit air leakage. Overall energy performance depends mostly on the glass package, frame, and installation quality, so we review the performance ratings for the specific casement configuration we quote. Explore WeatherMax window systems.
Because the sash opens outward, the screen mounts on the inside of the window. That keeps it protected from the weather and makes it easy to remove for cleaning.
Both open outward. A casement is hinged on the side and opens like a door, while an awning window is hinged at the top and opens outward from the bottom. Casements are common as standalone windows or flanking a picture window; awnings are often placed above or below other windows. Compare awning windows.
