    Abstract: A frame for a façade, a façade element, a window or a door is formed from a number of profiled elements, at which an insulating glazing unit having at least two glass panes held at a distance from one another is retained. An intermediate space under negative pressure is formed between the glass panes. The insulating glazing unit is clampingly retained at the edge thereof between an inner sealing profiled element and an outer sealing profiled element and pressure strips are provided on the exterior of the insulating glazing unit, which pressure strips are fastened to the profiled elements of the frame. A thermal-conductor arrangement is provided on and/or in the inner sealing profiled elements at least in some areas. Due to the thermal-conductor arrangement, heat can be fed to the edge of the insulating glazing unit lying against the inner sealing profiled element in the event of cold outside temperatures.
