Abstract: An architectural glass unit comprises a glass light having an inner surface and a flexible structural gasket extending along edges of the glass light and located adjacent the inner surface. A thin adhesive layer bonds the glass light firmly to the structural gasket. A supporting frame extends along the same edges of the glass light and is located on the side of the gasket opposite the glass light. This frame includes means for mechanically fastening the structural gasket to the frame. In one embodiment, a bonding material such as structural silicone directly bonds the glass light to the supporting frame and is arranged along one side of the gasket. L-shaped flanges integrally formed on the frame and rolled into sealing engagement with the gasket are used for the mechanical fastening.
