Which window type opens outward from the side hinge?

• A. Casement window
• B. Awning window
• C. Single hung window
• D. Jalousie window

Answer: (A)

Casement window opens outward from a side hinge. It’s attached to the frame on one side and swings away from the building, usually with a crank to operate it, giving a wide, unobstructed opening when open. This differs from an awning window, which is hinged at the top and swings outward from the bottom edge; a single-hung window where the sash slides vertically and isn’t hinged on the side; and a jalousie window that uses multiple glass slats that tilt open or closed. Knowing this helps with egress and rescue planning, since the hinge side and opening direction affect how the window clears the opening and what may block it.
