(重定向自Jalousie glass)
A jalousie window US or louvre window (Australia, New Zealand, Pacific Islands, Southeast Asia, United Kingdom) is a window composed of parallel glass, acrylic, or wooden louvers set in a frame. The louvers are joined onto a track so that they may be tilted open and shut in unison to control airflow, usually by turning a crank.
