A casement window is a type of window that is attached to its frame by one or more hinges at the side. They can be used singly or in pairs within a common frame, in which case they are hinged on the outside. Unlike most windows that open by sliding up and down or side to side, casement windows open with a side hinge, just like a door, and a window crank mechanism that sweeps the window open outward. When completely open, the window sits perpendicular to the side of the house. When cranked into a closed position, an inside latch is used to seal it tight.
Casement windows were common in Britain and Ireland before the sash window was introduced. They were usually metal with leaded glass, which refers to glass panes held in place with strips of lead called cames. Casement windows are also excellent for natural ventilation strategies, especially in hot climates. They allow more control of ventilation than flush-opening windows. They can be hinged to open outward and angled in order to direct breezes into the building.
Casement windows provide unobstructed views and are great for natural ventilation. They are also designed to be easily accessible from the inside, making maintenance a breeze. They come in a broad range of styles and sizes and blend well with other window designs.
