Abstract
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 an extruded rigid thermoplastic, such as polyvinylchloride (PVC), which is fixed to the roof construction about the opening. The rigid thermoplastic curb has a top co-extruded flexible thermoplastic (such as PVC) gasket integral with the curb and compressible against the edge of the glass or plastic dome or panel, a second flexible integral co-extruded thermoplastic gasket adapted to contact a retainer secured to the curb for retaining the dome or panel on the curb, and a third co-extruded flexible gasket adapted to contact and seal between the curb and a support wall there below preferably against an outer aluminum wall. The curb is provided with two recesses at its bottom which permit a snap engagement of the inner and outer aluminum walls which form the support for the curb. This snap engagement eliminates welding.
