A casement window is a type of window that is hinged on one of its vertical sides and swings outward, either to the left or right, like a door. This design allows for maximum ventilation when fully opened. Casement windows are available in various styles and materials, and are a popular choice in both residential and commercial construction. The operation of a casement window is controlled by a crank or lever, which allows the window to be easily opened or closed.
