  • the second brush 72 has a second stocking width preferably between 2 mm to 10 mm, particularly preferably between 3 mm to 7.5 mm, and a second stocking height preferably between 1 cm to 2.5 cm, particularly preferably 1 cm to 1.5 cm , on.
  • the bending stiffness of the first brush 71 is greater than the bending strength of the second brush 72.
  • the bristles or fibers, from which the trimmings 82, 88 of the brushes 71, 72 are formed have a sufficient bending stiffness to a sufficiently good tightness the first brush 71 and the second brush 72 against mechanical or pneumatic influences, on the other hand, however, cause no damage to the surfaces of floor and / or ceiling guides when moving the door leaf elements 3 in the sliding wall system 1. This is important because in addition to sand and scratch-resistant mineral floor coverings, especially in the floor area, materials such as wood are increasingly being used whose sanding and scratch susceptibility is significantly higher.
  • the material of the first trimming 82 has a first bending stiffness between 0.07 Nmm 2 and 0.3 Nmm 2 , preferably between 0.07 Nmm 2 and 0.15 Nmm 2 .
  • the material of the second trimming 88 has a second bending stiffness of 0.064 Nmm 2 .
  • the bending stiffness can be measured according to DIN EN ISO 22254.
  • the gap between the two adjacent door panel members 3 may vary over time due to frequent use or relative movement as well as thermal expansion or contraction.
  • the gaps may also be different between different adjacent door leaf elements. Since the second trimming material of the second brush 72 is soft, these variations can be compensated. Variations of the gap between the mounting profile 4 and the ceiling guide 2 are usually smaller, especially when a single integral ceiling guide 2 is used for all door leaf elements, whereby a lower flexural rigidity is justified.
  • the first brush 71 has a first plastic film 80a and the second brush 72 a second plastic film 80b, wherein the first plastic film 80a in the first brush 71 and the second plastic film 80b in the second brush 72 is arranged centrally.
  • the first plastic film 80a is made of polyethylene.
  • polyethylene has a high toughness and elongation at break, a good sliding behavior, a low wear, a high temperature resistance and a very low water absorption.
  • the first plastic film 80a is single-layered and the second plastic film 80b is double-layered.
  • the first plastic film 80a preferably has a first film thickness between 30 .mu.m and 200 .mu.m, particularly preferably between 50 .mu.m and 150 .mu.m.
  • the second plastic film 80b has a second film thickness between 30 .mu.m to 200 .mu.m, particularly preferably between 50 .mu.m and 150 .mu.m.
  • the material strength of the flexibility of the first brush 71 and the second brush 72 can be controlled.
  • the specified film thicknesses show an optimum sealing effect.
  • a first film height of the first plastic film 80a in the first brush 71 is between 100% and 150%, preferably between 105% and 125% of the first stocking height of a first stocker 82 of the first brush 71.
  • the second plastic film 80b in the second stocker 72nd has a second film height between 100% and 150%, preferably between 105% and 125%, of the second stocking height of a second stocking 88 of the second brush 72.
  • the first plastic film 80a in the state arranged in the first brush 71 is 2% to 20%, preferably 5% to 10%, in relation to a first brush height inwards, to the first base region 81 of the first brush 71 and the second plastic film in the state arranged in the second brush 72 are set back by 2% to 20%, preferably by 5% to 10%, in relation to a second brush height to a second base region 87 of the second brush 72.
  • a good engagement of the second plastic films 80b of two adjacent door leaf elements 3 in the closed position and consequently an improved sealing effect is effected.
  • each of the first brushes 71 contacts the bottom and / or the surfaces with a contact pressure of 0.01 N / mm 2 to 0.5 N / mm 2 Ceiling guide 2.
  • the second trimming 88 engages opposite second brushes 72 of two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding wall system 1 each other.
  • the adjacent door leaf elements 3 remain sealed against each other, even if the gap is larger by eg wear of the second brush 72.
  • the second trimmings 88 of opposing second brushes 72 of two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding wall system 1 a coverage of 2% to 20%, preferably from 5% to 15% based on the second stocking height of second brush 72 on.
  • the two layers of the second plastic film 80b in the state arranged in the second brush 72 have a substantially identical second film height. This leads to a uniform load and thus to a comparable wear of the two layers.
  • the two layers of the second plastic film 80b directly adjoin one another, in particular without interposition of bristle fibers.
  • the two layers form a unit which can better withstand mechanical or pneumatic influences and causes improved tightness.
  • the second plastic foils 80a of opposing second brushes 72 of two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding wall system 1 have a coverage of 1% to 20%, preferably 2% to 10%, based on the second foil height of the second brushes 72 on.
  • the sealing effect can be further optimized.
  • the second brushes 72 are substantially identical to opposing second brushes 72 of two adjacent door leaf elements 3.
  • the sliding wall system has in particular an air permeability based on the joint length of 5 m 3 / hm to 20 m 3 / hm, preferably 10 m 3 / hm to 20 m 3 / hm, at a differential pressure of 200 Pa, measured according to EN1026 on.
