Casement Window

Definition and meaning of Casement Window in real estate.

A casement window is a window hinged on its side that swings outward to the left or right, typically operated by a hand crank. This style provides excellent ventilation and unobstructed views compared to double-hung windows.

In more detail

These windows feature a tight seal around the frame when closed, making them highly energy efficient and resistant to drafts. Because the window sash presses firmly against the frame seal, it minimizes air leakage during windy weather. They are common in modern homes and are often placed in hard-to-reach locations like above kitchen sinks where cranking is easier than lifting. Homeowners should regularly inspect and lubricate the crank mechanism to ensure smooth operation.

Frequently asked questions

Are casement windows more secure than double-hung windows?

Yes, the lock mechanisms are built into the frame and are hook-shaped, making them very difficult to open or pry from the outside.

Do casement windows open inward or outward?

Most casement windows are designed to swing outward to maximize interior living space and prevent rain from entering the room.
