ABSTRACT:
A ventilating skylight including a housing having a top wall and a pair of opposed sidewalls extending downwardly from the top wall to respective roof mountings so that the housing may be fixed to a roof at opposite sides of a roof skylight opening. The housing includes front and rear openings through which sunlight may pass to the skylight opening, and a transparent or translucent dividing wall assembly is provided having front and rear portions which extend upwardly and inwardly from the front and rear openings and form the base wall of an air flow passage extending between the front and rear openings. An intermediate vent opening is provided in the base wall assembly which communicates with the flow passage for directing air flow to the skylight opening. A water trap arrangement is associated with the vent opening for obstructing rain water passing along the base wall towards the vent opening. Closure flaps are provided for closing the front and rear ends of the flow passage, with each closure flap being pivotable between an open position in which the flap does not obstruct air flow through the respective opening and a closed position in which the flap extends across the respective opening. The closure flaps are biased to an open position and are movable to the closed position by aerodynamic forces.
