Abstract: In an edge connection for the panes (1, 2) of a compound glass element there is provided a spacing profile (3) which preferably consists of a poorly heat-conductive plastic material. This is adhered between the panes with a contact adhesive (4). As a vapour-barrier, a band (5) of a thin flat metal foil is applied around the exterior of the spacing profile. The outer surface (3.1) of the spacing profile is inwardly offset with respect to the flat metal band in the edge regions adjacent the panes, in such a way that peripherally running chambers (6) are created. These chambers are filled with a vapour-proof adhesive, preferably butyl-adhesive.

Abstract: The glazing element is provided with at least one tensioned insulation form (2) between two panes (1). Spring elements (3) secured to a tension profile (4) serve to place the film under tension. The spring elements are distributed over the entire film periphery. They are also elastically bendable in all directions transverse to their elongation, and are secured with their longitudinal direction essentially perpendicular to the film plane with one end at the film and the other end secured to the tension profile In this manner, the spring elements can elastically follow relative shape alterations of the film with respect to the tension profile by bending transversely to their longitudinal direction. In this novel construction, tension forces are distributed in all directions in the insulation film. No friction forces need to be overcome in order to tension the film. The entire tension taken up by the film support is so small that it is possible simply to adhere the tension profile inwardly to the panes.
