Such a frameless door or window is from the FR 2 662 739 A1 known. Similarly, a frameless window from the FR 2 142 064 A1 known.

It is increasingly the trend in business portals, in the field of offices and in modern architecture to use sliding glass doors and windows. Sliding glass doors, by eliminating the opening angle as it is given in hinged doors, bring more usable space and give a certain perspective in both directions and contribute to the openness and the connection between inside and outside.

In addition, continuous glass facades have established themselves in today's architecture, whereby frame parts of windows and doors in the glass facade are perceived as disturbing.

From the AT 9 285 U is an initially mentioned frameless door or a window known. This door or window gives the visual impression from the outside that the glass surface is not disturbed.

The object of the invention is to provide a door or a window of the type mentioned for example a glass facade, on the one hand avoids the above disadvantages, provides optimal thermal insulation and on the other hand, an economical production and assembly allowed.

The object is achieved by the invention.

The invention is characterized in that at least one insulating element is provided in the space of the main carrier of the lower floor frame part, wherein the insulating element forms a plane with the outer contour of the main support and on the insulating a running rail for the lift-slide fitting is provided and that in space the main carrier of the upper floor frame part at least one insulating element (21) and a guide rail for the sliding movement is provided, wherein the guide rail is arranged on the insulating element. With the invention, it is possible for the first time to ensure high stability for the operation of the frameless door or the window through the, preferably circumferential, dimensionally stable main support. Furthermore, given by the arrangement of the insulating thermal breaks, which mean a huge improvement in the heat transfer coefficient. This optimization of the heat transfer coefficient thus results in a large saving in energy costs compared to conventional constructions in this field. An economical production of the recesses in the main carrier by, for example, simple milling operations is guaranteed. Due to the arrangement of the running rail and also the guide rail on the insulating the running rail or the guide rail, the in many cases represents a cold bridge, thermally separated. The heat transfer coefficient is thereby set very low

For the sake of order, it is stated that the opening width generally corresponds to the sliding door or sliding window width. The displacement length therefore corresponds to twice the opening width. The insulating elements are preferably plastic profiles, which are formed according to their use.

According to a further particular feature of the invention, the insulating element is offset outside the room, wherein preferably the profile of the running rail projects beyond the paragraph and in the remote area a, preferably U-shaped, Rigol, preferably with an inlet grid, is arranged.
