(French: "breaks the sun") Sun baffle of vertical or horizontal louvers outside the windows or extending over the entire surface of a building's facade, especially precast concrete grids of the type developed by Le Corbusier .
Many traditional methods exist for reducing the effects of the sun's glare, such as the projecting upper-story window of latticework ( mashrabiyah or mushrabiyah ) used in Islamic architecture, pierced screens as used at the Taj Mahal , or blinds of split bamboo ( sudare ) as used in Japan.
