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 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
A skylight construction for an opening in a building comprising; a frame means extending about the opening and including means securable about the opening, translucent or transparent means covering the opening and extending at edges to overlie the frame means, means for retaining the covering means on the frame means, said frame means comprising a base frame and a support frame overlying the base frame, and a compliant sealing means extending contiguously about and overlying the base frame and for sealing between the base frame and support frame, said base frame having thermal break means for minimizing heat transfer through the base frame, said support frame including an inner frame section, an outer frame section and second thermal break means disposed between and joining the inner and outer frame sections, said inner frame section having an upright wall forming a means on one side for holding the second thermal break means and forming on the other side thereof, at least a part of a condensation gutter, a gasket carried by and overlying the inner frame section, and means defined in the inner frame section over the upright wall for retaining the gasket in place.
Claim 2
Dependent Claim
