• a first glass plate with a first glass plate thickness and a first edge;
• a second glass plate with a second glass plate thickness and a second edge, the second edge aligned with the first edge to form a common plane;
• an intermediate layer which directly connects the first and the second glass plates together, the intermediate layer being formed of a material other than glass;
• at least one connecting element, wherein the first and second glass plates are positioned in parallel spaced planes forming an intermediate space therebetween and the intermediate layer substantially fills out the intermediate space between the first and second glass plates, wherein a thickness of the intermediate layer is at least equal to half of one of the first and second glass plate thicknesses, wherein the connecting element is embedded only in an edge region of the lightweight glass plate in the intermediate layer, and wherein the intermediate layer penetrates into a space between the connecting element and the first and second glass plates;
• and
• a sealing material attached to both the first and the second glass plates within the edge region of the intermediate space not occupied by the intermediate layer, the connecting element extending through the common plane and the sealing material and into the intermediate layer.
