The glazing comprises two identical transparent elements each with an integral pane portion and an edge portion having sealing ribs. Internal covering means comprising two wall sections, overlap each other to provide an inner seal. The height of the wall is less than the thickness of the sandwich material, and the walls may also interengage and interlock. |
