A movable window having a side-hinged sash that swings outward is called a

• A. Casement window
• B. Awning window
• C. Double-hung window
• D. Fixed window

Answer: (A)

This describes a casement window. A casement window is operable and hinged on the side, so the sash swings outward away from the frame, typically operated by a crank. This sets it apart from other common window types: an awning window is hinged at the top and opens outward from the bottom; a double-hung window has two sashes that slide vertically; a fixed window does not open at all. In practice, casement windows can provide a wide, clear opening for ventilation, and when closed they seal along multiple contact points for weather-tight performance. Understanding these differences helps in assessments of egress and ventilation, ensuring openings are usable and clear of obstructions during a fire inspection.
