Abstract

The skylight may be of the domed-type or flat type and of single or double glass (acrylic or other transparent or translucent plastic) construction. The skylight fits within an opening in a roof or the like and has a peripheral curb of aluminum or the like material which is fixed to the roof construction about the opening. The curb member or frame at its top receives a flexible thermoplastic (such as PVC) gasket compressible against the edge of the glass or plastic dome or panel. In accordance with one embodiment of the invention the frame may be constructed of a material such as PVC, in which case the top gasket may be integral with the frame or curb. In this case there may also be a second flexible thermosplastic gasket adapted to contact a retainer secured to the curb for retaining the dome or panel on the curb. In another embodiment of the invention the frame or curb may be constructed of aluminum or the like having a thermal bridge associated with the frame to minimize the transfer of heat from one side of the frame extrusion to the other. The frame may also have associated therewith stops extending upwardly for limiting the position of the domes or panels. These stops are useful in transportation of the unit and also when the unit is to be installed on a slanted roof.
