Abstract: A glass panel assembly includes at least one elastomeric base plate which is received on a supporting frame structure, at least one elongated rigid attachment element received on the base plate for attaching it to the frame structure, at least one glass panel received on the base plate so that it is supported thereon and at least one pressure plate received on the glass panel and secured to the attachment element for securing the glass panel in the assembly. The assembly is adapted to compensate for dimensional irregularities and different angular planes in the supporting frame structure as well as differences in the thermal expansion properties of the various components in the assembly and the support frame structure. The assembly is further adapted to minimize thermally conductive paths between interior and exterior assembly components in order to minimize condensation on interior components, and the one or more base plates of the assembly include gutters for removing moisture from the assembly.
