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. There is also provided 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. The rigid curb is of a thermoplastic in the shore 'D' durometer hardness scale, while the flexible gaskets are of a thermoplastic in the shore 'A' durometer hardness scale. A heat platten welding technique, which would most commonly be used in welding the curb frame mitres, would also weld the gaskets simultaneously for a continuous seal. Other less commonly used thermoplastic welding techniques, such as ultrasonic, hot gas, high frequency and friction, could be employed to accomplish the simultaneous bond at the corners.
