Aluminum Louver Frames are used as semi-passive means of thermal control on airplanes and spacecraft as well.
Rear window louvers are also available as an accessory for some automobiles. They have also been used over the years in hoods, trunk lids, and other various body panels; typically hot rods, but by no means exclusive to that period. Their purpose in this regard is both as a functional means of ventilation, but also as a styling modification.
Louvers may also be used on traffic light lenses to prevent traffic from seeing the wrong traffic signal.
