ABSTRACT:
A skylight assembly is provided to be mounted to cover an opening in a roof structure. The assembly includes a liner adapted to be mounted adjacent the edge of the opening in the roof structure around the periphery to surround the opening and to form a wall extending upward from the roof structure. An outer dome and an inner dome are provided with the domes spaced and the outer dome overlying the inner dome. Both of the domes engage a sealing gasket positioned on the liner wall. A supporting frame is coupled to the dome and sealing gasket arrangement and the frame and arrangement are hinged to the liner to permit shifting thereof with respect to the liner between a closed position overlying the opening in the roof structure and an open position permitting access to the opening from the exterior of the roof structure. The supporting frame has a U-shaped end portion to receive the peripheral edge portion of the outer dome therein and thereby support the outer dome. The manner of engagement between the frame and the outer dome enables the assembly to resist significant tension forces. A weep hole is provided in the frame to alleviate the danger of condensation in the portion of the outer dome enclosed by the frame and gasket. The exposed peripheral edge of the outer dome is protectively enclosed.
