- Louver
:"For the French museum, see the
Louvre "A louver (American English) or louvre (British English), from the French "l'ouvert"; "the open one") is a window, blind or shutter with horizontal or, less often, vertical slats, which are angled to admit light and air, but to keep out rain, direct sunshine, and noise. The angle of the slats may be adjustable, usual in blinds and windows, or fixed. As building management services has improved and technology has quickly changed, these louvers have been automated to save on overall cost while providing a pleasant living environment inside buildings.Louvers originated in the
Middle Ages as lantern-like constructions in wood that were fitted on top of roof holes in large kitchens to allow ventilation while keeping out rain and snow. They were originally rather crude constructions consisting merely of a barrel. Later they evolved into more elaborate designs made of pottery, taking the shape of faces where the smoke and steam from cooking would pour out through the eyes and mouth, or into constructions that were more like modern louvers, with slats that could be opened or closed by pulling on a string.More modern louver windows comprise slats of glass, opened and closed with a metal lever, or they may be shutters of wood or other material.
