3/777 MD:nm 5/80 THERMAL BREAK SKYLIGHT Abstract of the Disclosure 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 corres- ponding to the opening size with mitred and vulcanized cor- ners thus providing an optimum seal.
