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.

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.

The rigid thermoplastic curb has a top co-extruded flexible thermoplastic (such as PVC) gasket intergral 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.

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 base that may be constructed of a metal material such as aluminum, and which is fixed to the roof construction about the opening. The base comprises inner and outer base frames separated by a thermal break, a peripheral curb frame disposed over the base, and a retainer for securing the skylight dome over the curb frame. In one embodiment the thermal break is formed by a separate gasket preferably in the form of a pre-molded butyl tape with a neoprene shim. The curb frame is sealed to the base by means of a hollow second gasket preferably secured to the base but separate from the butyl gasket. In another embodiment, a foam rubber gasket is employed having an enclosed hollow tube for maximum compliance functioning both as the thermal break and as the gasket between the base and the curb frame. The gasket is provided in rectangular sizes corresponding to the opening size with mitred and vulcanized corners thus providing an optimum seal.

A skylight that may have a domed-type or flat-type glazing and which is adapted to fit within the opening of a roof or the like having a peripheral frame which is fixed to the roof about the opening. The frame is constructed including a base frame and an operating leaf frame usually referred to as an operating leaf frame or operating leaf. A retainer is used for securing the skylight cover over the operating leaf frame. The frame comprises a rigid plastic profile (core) having high temperature resistant properties and a plastic capping material extruded over the external exposed surface of the core to protect the profile from weathering. There is also preferably provided with the profile and capping, a flexible gasket means which may include respective gaskets associated with both the base frame and the operating leaf frame.

A safety vent preferably for use in a high rise building for permitting the escape of smoke and fumes and comprising a fixed frame accommodated by an opening in the building, a movable frame pivotally secured to the fixed frame and means for biasing the movable frame to an open position. In the preferred embodiment the movable frame includes panel means and pivots at its lower end. A latch mechanism maintains the movable frame in a closed position while a release mechanism, operated either electrically or pneumatically, can be energized to permit opening of the vent. Limiting means in the form of shock absorbers or snubbers interconnect between frames for limiting the open position of the vent.
