Definitions

  • the present invention relates to a fire bar for building facades with a thermal insulation composite system, a building facade comprising the fire bar, and the use of the fire bar.
  • Building insulation is an essential part of new construction and renovation of buildings.
  • the outer facades of buildings are provided with thermal insulation panels in order to significantly reduce the passage of heat through the facades.
  • the heating energy required in winter and the energy required for cooling in summer can be significantly reduced.
  • Thermal insulation panels that are frequently used are rigid foam panels made from foamed plastics, in particular from foamed polystyrene, such as expanded polystyrene (EPS) and/or extruded polystyrene (XPS).
  • foamed polystyrene such as expanded polystyrene (EPS) and/or extruded polystyrene (XPS).
  • EPS and XPS panels are not only relatively inexpensive to produce, but they also have very good thermal insulation properties.
  • EPS and XPS panels are not only relatively inexpensive to produce, but they also have very good thermal insulation properties.
  • EPS and XPS panels are not only relatively inexpensive to produce, but they also have very good thermal insulation properties.
  • they are easy to process. For example, they can easily be cut to a desired size.
  • differences in surface area between different panels can be easily leveled out after they have been applied to the house wall due to their material properties.
  • EPS and XPS boards are classified as combustible building materials and flame-retardant EPS and XPS boards as hardly combustible building materials.
  • fire breaks are installed in the thermal insulation of the building facade, especially in larger buildings.
  • Such fire bars are often above Building openings such as windows and doors are attached to prevent the fire from spreading through the building opening to the thermal insulation of the facade in the event of a fire inside the building.
  • fire breaks are also typically used horizontally across an entire facade or even as a horizontal fire break band running around the entire building, consisting of a large number of individual fire breaks. This prevents sources of fire and fire from spreading to the entire facade.
  • the DE 20 2007 007 225 U1 describes a component for a thermal insulation composite system comprising two insulating elements and a fire protection layer made of a non-combustible material such as mineral wool, the fire protection layer being arranged between the two insulating elements and extending essentially over the entire cross-sectional area of the component.
  • the insulating elements are preferably made of expanded polystyrene, but can also consist of polyurethane, for example. If the insulating elements are made of expanded polystyrene, the surface of the component can be well matched to the adjacent insulating elements through abrasion. However, the material does not form a suitable fire barrier against fire. If the insulating elements are made of polyurethane, they form a suitable fire barrier, but its surface cannot - or only extremely badly - be matched to the surfaces of the adjacent insulating panels.
  • fire bars made of polyurethane (PUR) and polyisocyanurate (PIR) rigid foam with increased density are often used.
  • PUR polyurethane
  • PIR polyisocyanurate
  • Thermal insulation panels made of hard foam, which has on the side facing the wall at least one substantially the entire panel length and panel thickness penetrating recess, which preferably with mineral wool, respectively. is filled with polyurethane or polyisocyanurate rigid foam.
  • the EP 2 706 160 A2 describes facade panels for exterior walls of buildings, the panel body comprising a fire protection body which extends along at least one side of the panel body, the fire protection body being covered on at least one longitudinal side by an adaptation layer which is preferably formed in one piece with the panel body. In order to produce such plates, however, an increased effort is required.
  • the object of the present invention is therefore to provide a fire bar for building facades with a thermal insulation system, which eliminates the disadvantages of the prior art and allows simple and unproblematic mechanical abrasion of the individual insulation panels and the fire bar - and thus leveling out any unevenness that has arisen - without adversely affect the subsequent processing step(s), such as applying a plaster.
  • the fire bar should be available separately and not integrated in a thermal insulation panel, which means that the fire bar is attached to the facade independently of thermal insulation panels. This should significantly reduce or even rule out incorrect assembly.
  • a building facade with a thermal insulation composite system (1) comprising a facade (2), an insulating board (3), in particular an upper (3') and a lower (3") insulating board, and the fire bar (45) claimed according to the invention, wherein the fire bar (45) and the insulation board (3) are attached to the facade (2) and the fire bar (45) is adjacent to the insulation board (3) with the thinner layer (51) of the fire bar (45) on the side of the fire bar (45) is arranged, which faces the facade (2).

  • the layer (51) made of polystyrene foam - which is part of the fire bar (45) - due a below the fire bar (45) located fire melts away and the molten polystyrene drips down, the heat can resp. do not spread the fire upwards through the resulting thin gap between the remaining fire bar (45) and plaster (7) applied to the insulating board (3) and fire bar (45). In this way, little or no insulation material located above the fire bar (45) melts.
  • the building facade according to the invention with a composite thermal insulation system (1) can be produced in a simple manner. It was found that not only can a source of fire and fire be contained locally by using the fire bar (45) according to the invention and that the fire does not spread beyond the fire bar (45) according to the invention, but the surface of the building facade (1) with applied Surprisingly, the thermal insulation composite system can also be reworked without any problems and without the formation of dust, in order to be completely flat for a subsequent layer - for example plaster. This is particularly the case when the insulating panels (3) and the thin layer (51) of the fire bar (45) are made of the same material, i.e.
  • the fire bar (45) when they are advantageously both made of expanded polystyrene (EPS) or extruded polystyrene (XPS ) consist.
  • EPS expanded polystyrene
  • XPS extruded polystyrene
  • protruding corners and edges can be easily removed without creating dust.
  • the adhesion to a subsequent layer such as a layer of plaster
  • the insulating panels (3) can also be cut to size without any problems when creating the building facade (1) according to the invention without running the risk of a fire bar integrated therein being partially or completely cut off by mistake.
