a first pane and a second pane arranged parallel to the first pane;
an intermediate adhesive layer arranged between the first pane and the second pane and forming a laminate therewith, the intermediate adhesive layer comprising a layer opening or recess surrounded by an inside opening wall of the intermediate adhesive layer;
a reinforcing adhesive material in the layer opening or recess of the intermediate adhesive layer and having a higher strength or hardness than the intermediate adhesive layer, wherein the reinforcing adhesive material is coplanar to the intermediate adhesive layer; and
at least two separate accesses extending from an outside of the window pane to an inside of the layer opening or recess,
wherein
a first access of the at least two accesses is configured to supply the reinforcing adhesive material in liquid form to the layer opening or recess,
a second access of the at least two accesses is configured to vent the layer opening or recess to the outside of the window pane during supplying of the reinforcing adhesive material in the liquid form to the layer opening or recess,
at least one of the accesses comprises a through hole in at least one of the first pane or the second pane,
the layer opening or recess in the intermediate adhesive layer has opposing ends and corresponding opposing end portions, and each of the opposing end portions includes a through hole,
separate upper and lower through holes extend from the outside of the window pane to the inside of the layer opening or recess,
one through hole is an upper through hole and another one through hole is a lower through hole,
the upper through hole is in an upper corner or near an upper portion of the inside opening wall of the opening or recess,
the lower through hole is in a lower corner or near a lower portion of the inside opening wall of the layer opening, and
one of the first and second panes is an outer glass pane, and the other of the first and second panes is an inner glass pane,
the upper through hole is provided in the inner glass pane for supplying the reinforcing adhesive material in the liquid form to the layer opening or recess, and
the lower through hole extends through the inner glass pane, the reinforcing adhesive material, and through the outer glass pane, wherein the lower through hole is provided for venting the layer opening or recess to the outside of the window pane during supplying of the reinforcing adhesive material in the liquid form through the upper through hole into the layer opening or recess, and for holding and clamping the window pane in the vehicle.
