Window or door

Window or door assembly, comprising a support frame;

• a retaining frame spaced from said support frame and mounted thereto by frame connecting elements, each of said frames having a frame plane;
• a multiple insulating glass including at least two glass panes spaced from each other to form an intermediary air space therebetween, the weight of said multiple insulating glass being absorbed by said support frame, said support frame and retaining frame each having a longitudinal bar;
• at least two pane gaskets each being engaged between the respective glass pane and the respective longitudinal bar, said pane gaskets forming a steam tight closure over a total circumference of the respective glass pane, said connecting elements connecting the frames to each other such that a displacement slot is formed between said frames and the retaining frame at its entire periphery is displaceable relative to the support frame in the direction perpendicular to the frame so that air volume changes of the air between said two panes and pressure fluctuations of the air in outer atmosphere do not cause substantial additional loads in said gaskets and substantial buckling of said panes;
• and a frame sealing profile positioned between the retaining frame and the support frame so as to bridge said displacement slot between two frames, said profile having an elastic expansion fold and closing said air space between the two glass panes over the total circumference thereof steam tight against outer atmosphere.
