FIELD: construction.
SUBSTANCE: invention relates to construction, in particular to the structures of rooflights, providing natural lighting of premises and smoke removal through a movable dome located in the plane of the roof, and can be used in ventilation structures of buildings and fire safety equipment. The technical result is achieved by the fact that the skylight consists of a base, a two-winged dome, a hinged connection of the flap with the base and a drive for lifting the dome, while the base is connected to one of the flaps, to which the second flap is movably connected with the possibility of its rotation relative to the first flap simultaneously with the rotation of the first sash relative to the base.
EFFECT: simplified design, increased reliability, reduced windage, increased efficiency by removing obstacles in the path of air flow and reducing material consumption.
