Sliding wall systems and their door panels are known, for example, in multi-leaf entrance doors, wall sliding elements used as a room divider or wall elements in front areas of buildings, especially in restaurants and shops, to keep the shop open or closed according to the weather. The door leaf elements are usually movably received in ceiling mounted ceiling guides. In this case, the individual wing elements can be parked in a lateral position, so that there is no hindrance to the entering public traffic.

Due to increasing requirements for energy efficiency in and on buildings, the requirements for thermal insulation of such sliding wall systems are also increasing.

By this configuration, a secure and stable connection between the insulating webs and frame profiles of a sliding wall system is effected as well as easy manufacturability by a simplified joining of insulating bars with the frame profiles. Furthermore, the thermal effective contact area is optimized with respect to the effective load transfer area.

It is particularly preferred that the angle β1 between 50 ° -60 ° and the angle β2 is between 60 ° -80 °, whereby the advantages of the invention can be further optimized.

To further optimize the thermal contact, it is also advantageous that the free legs of the U-shaped groove-like receptacle protrude from the longitudinal side of a profile and the base side of the groove-like receptacle is formed with the longitudinal side in alignment. The thus formed thermally effective ribs lead to an optimized thermal contact between the groove-like receptacles and the insulating bars.

Further, the second door panel 400b is pivotally and slidably disposed in the ceiling guide 200. Thus, the first door leaf element 400a and the third door leaf element 400c serve as sliding sash, the fourth door leaf element 400d as a rotary wing or pendulum wing and the second door leaf element 400b as a rotary sliding sash.

The gap between the door panel members 400a, 400b, 400c, 400d and the ceiling guide 200 or the building floor 101 may vary due to mounting tolerances and / or over time due to frequent use or relative movement as well as thermal expansion or contraction. This gap is optically and thermally sealed by means of horizontally extending brushes 490a, 490b, with the brushes 490a, 490b on the ceiling-side horizontal door leaf frames 410ab, 410bb, 410cb, 410db and / or the bottom horizontal door leaf frames 410aa, 410ba, 410ca, 410da of the door leaf elements 400a , 400b, 400c, 400d are arranged.

Fig. 2 shows a cross section through the ceiling guide 200 of the Fig. 1 known sliding wall system 100. The ceiling guide 200 is fixed to the building ceiling 201. The ceiling guide 200 comprises a running rail 300 in which a roller carriage 500 is displaceably arranged. On the roller carriage 500, a door leaf element 400 is arranged hanging.

The running rail 300 is substantially U-shaped, with the free legs of the U-shaped running rail 300 forming the end faces 301a, 301b of the running rail 300. Further, in particular at the distal end of the free legs of the U-shaped running rail 300 running surfaces 302a, 302b for guiding the roller carriage 500 are formed.

The rail 300 is formed of a first material having a thermal conductivity of 75-235 W m ^-1 K ^-1 and a thermal expansion coefficient of 21-24 * 10 ^-6 K ^-1 .

Preferably, both end faces 301a, 301b of the running rail 300 have a surface roughness parallel to the extrusion direction of Ra 0.1-3, preferably Ra 0.2-2, particularly preferably Ra 0.75-1.8 measured according to DIN EN ISO 4287 , As a result, particularly advantageous adhesive and contact properties for the thermal separation profile to be fastened to the running rail, which will be explained in more detail below, can be achieved.

The thermal separating profile 320 is arranged on an end face 301b of the running rail 300 via a fastening means 325, in particular a screw, clamping or glued connection. Although in Fig. 2 only a thermal separation profile 320 is disposed on one of the end surfaces 301b, it is of course possible and advantageous to provide a thermal separation profile on both end faces 301a, 301b.

The thermal separation profile 320 abuts against the end face 301b of the running rail 300. For the installation, the thermal separating profile 320 comprises a plurality of mutually separated contact surfaces 321a, 321b, 321c, 321d between the thermal separating profile 320 and the end face 301b of the running rail 300. In order to further improve the thermal separation, it is preferred that the entire contact surfaces 321a , 321b, 321c, 321d of the thermal separation profile 320 correspond to 1-10% of the area of an end face 301b of the track rail 300.

At the plant leg 324, a groove-like guide 326 may be provided for receiving the free bristle ends of a brush 490a. The guide 326 is formed in such a way that the free bristle ends of the brush 490a arranged beneath the running rail 300 in the horizontal door leaf frame 410 are enclosed at least in sections by the groove-like guide 326. This results in a visually appealing joint image of the sliding wall system 100, since fraying of the bristle ends of the brush 490a, which usually occurs during operation of sliding wall systems, is visually obscured by the groove-like guide 326. Further, the groove-like guide 326 improves the windproofness of the sliding wall system, because by fixing the free end of the bristles of the brush 490a, this has an improved mechanical stability.

The thermal separation profile 320 is formed of a second material having a thermal conductivity of 0.02-0.1 W m ^-1 K ^-1 and a thermal expansion coefficient of 40-300 * 10 ^-6 K ^-1 .
