A casement window (or casement) is a window that is attached to its frame by one or more hinges. Casement windows typically are hinged at the side, sometimes at the top or bottom. They are used singly or in pairs within a common frame, in which case they are hinged on the outside.
Casement windows were the most common house window before the sash window was introduced, and usually contain leaded glass. These casement windows usually were hinged on the side, and opened inward. The windows were covered by functional exterior shutters, which opened outward.
They are opened with a crank or a lever or cam handle placed at around hand height or at the bottom and serve as window locks. A crank, stay, or friction hinge is necessary when the window opens outward, to hold the window in position despite wind.
Often the glass panes are set in a rabbeted frame and sealed with beveled putty or glazing compound to secure the glass.
