  • a large surface 16 arranged opposite the large surface 10 and running parallel to the large surface 10 has regions 17 in which mineral fibers 15 running obliquely to the large surface 16 and / or parallel to the large surface 16 are cutting away or dragging away, so that in these areas the mineral fibers 15 are oriented substantially perpendicular to the large surface 16.
  • the large surface 16 is partially covered with a lamination 18, wherein the lamination 18 consists of individual strips not shown in detail, which are glued with its longitudinal axis perpendicular to the longitudinal axis of the webs 9 extending on the surface 16 and thus the cohesion of the webs 9 in the area the large surface 16 support.
  • the lamination 18 is formed tensile and glued to the Mineratfaserdämmstoffelement 4 via a polyurethane adhesive.
  • a mesh fabric 19 made of glass fibers is inserted as a reinforcement.
  • FIG. 3 shows a second embodiment of a Mineralmaschinedämmstoffijnements 4 in side view, which differs from the embodiment according to FIG. 2 in the area of the large surface 10, the majority of the mineral fibers 15 running obliquely or parallel to the large surface 10 are removed by grinding or cutting.
  • the mineral fiber insulating member 4 detects FIG. 3 in the area of the large surface 16 instead of the lamination 18 in FIG. 2 an impregnation 20 of a mass 21 introduced between the mineral fibers 15, which solidifies and compacts the large surface 16.
  • the mass 21 consists of a fiber-reinforced bitumen-plastic material, wherein the fibers contained in the mass 21 are formed as mineral fibers.
  • the mass 21 may additionally be arranged as a coating not shown in detail on the large surface 16.
  • FIG. 1 Profile rails 12 shown connected to the roof substructure 2. This can be used by the design of Mineralmaschinedämmstoffmaschine 4 long rails 12 with U-shaped or Z-shaped or L-shaped cross-section.
  • the introduction of long rails 12 has the advantage that this introduction in a short time is possible and that the production of such rails 12 is cheap with great length.
  • These rails 12 are relatively stiff and form a stable support structure for an in FIG. 1 not shown roofing, which may for example consist of profiled sheets.
  • long rails 12 can of course also shorter rails 12 are used.
  • the short profile rails 12 have the advantage that they can be arranged flexibly. For this purpose, it is necessary for long rails 12 to cut them.
  • the penetration resistance of the profiled rails 12 described above can be reduced if the profiled rails 12 are formed in the region of the free ends of the legs 14 with not illustrated serrations or teeth.
  • the free ends of the legs 14 may be ground in a blade shape, so that penetration into the Mineralfaserdämmstoff electrode 4 is also possible without any problems if the Mineralfaserdämmstoffmaschine 4 have a higher density, for example, more than 90 kg / m 3 .
  • the building roof 1 described above is sufficiently pressure-resistant by the design of Mineralmaschinedämmstoffelements 4 and by the arrangement of Mineralmaschinedämmscherlements 4 in conjunction with a tear-resistant seal 5 relative to the trapezoidal sheets 6 of the roof substructure 2 to run on it with tires transport vehicles transporting insulation materials.
  • the accessibility and navigability of the building roof 1 is achieved in particular by the design of the Mineralfaserdämmstoff electrode 4 with the special fiber flow in combination with the seal 5 and the alignment of Mineralfaserdämmstoff institute 4 to the trapezoidal sheets 6. If the Mineralfaserdämmstoffmaschine 4 formed with their webs 9 in sufficient thickness and / or high density, so the seal 5 may differ from the above, even made of thin polyethylene films to form an airtightness layer.
  • FIG. 1 Not shown crowds are usually attached to the rails 12.
  • FIG. 1 are not shown in detail and connects the rail 12 with the trapezoidal sheets 6.
