Jalousie
From Wikipedia, the free encyclopedia
A jalousie is a slatted window covering, typically a shutter or window covering, which consists of a set of parallel angled slats. These slats can be opened variously so as to control the amount of air or light allowed to pass through.
A jalousie window has overlapping glass slats which open to allow ventilation. This kind of window is good for sun porches that are not airconditioned.
