Definitions

  • the invention relates to a method for producing outer surfaces of buildings, in particular thermally insulated outer surfaces, in which a layer of plate-like or sheet-like material is applied to the outer wall of the building, and to a sheet or plate material for carrying out the method.
  • Exterior walls of buildings are covered with coatings such as plastering and painting or cladding made of board material, ceramic boards, tiles or shingles or boards made of natural or artificial slate etc. for protection against weather influences as well as for aesthetic / aesthetic reasons.
  • coatings such as plastering and painting or cladding made of board material, ceramic boards, tiles or shingles or boards made of natural or artificial slate etc.
  • the so-called external insulation has become established both for the subsequent thermal insulation of older buildings and for the new construction of buildings, whereby a thermal insulation composite system (ETICS) is used to a large extent, in which thermal insulation boards are initially used on the shell of the building's outer walls, ie Water vapor diffusible hard foam panels or mineral fiber panels can be applied to the shell wall using adhesive points with adhesive mortar.
  • ETICS thermal insulation composite system
  • a mesh fabric is then used on the outside of these thermal insulation boards Carrier for a plaster applied, on which - after applying and setting the plaster - then finally the outer plaster representing the visible surface of the building or - at least in some areas, for example in the base area of a facade - also a slab, in particular a tile covering is applied.
  • the invention has for its object to provide a method for the production of building outer wall surfaces, which can be used both on the outer surfaces of building walls of unfinished buildings and on the outside of the building walls of older buildings, which already with an unsightly or damaged plaster, Clinker or panel covering or external thermal insulation are provided.
  • This object is achieved according to the invention in that on the outer surface of the building wall a layer of a clothing carrier formed by a film with a mesh fabric provided on the outside of the building facing away from it is applied so firmly that air spaces which are connected to one another between its underside facing the building and the outer wall of the building be formed that a hardening or setting plaster that surrounds the lattice fabric and is applied to the lattice fabric-facing side of the clothing carrier is applied and then solidified, and that an outer covering determining the appearance of the building wall is applied to the outside of the solidified plaster.
  • water vapor can diffuse out of the building wall and - if necessary - can be removed as condensate.
  • the continuous air space between the film and the outer wall of the building is preferably obtained by using a clothing carrier, in which the film is profiled by a plurality of projections protruding from the opposite side.
  • the film material used here can be used for other purposes, for example for draining and / or ventilating panel coverings laid outdoors, which are provided on one side with a high-strength mesh fabric serving as an adhesion promoter and / or for reinforcing the composite mortar for panel coverings to be applied.
  • profiled metal foils or sheets with thin walls for example made of aluminum or corrosion-resistant steel, can also be used.

  • the method according to the invention can therefore be used quite generally to create a plaster support system which is decoupled from the substrate and which push-proof insulation boards, cannot be used with substrates that can be plastered or for seamless plaster processing on old prefabricated house facades.

  • the profiled film is laid on the outside of the outer wall of the building in such a way that at least one passage to the ambient atmosphere is also formed in the upper horizontal edge region of the film which is remote from the floor.
  • This then provides rear ventilation of the additionally applied composite layer of film, plaster and outer covering, which functionally guarantees removal of water vapor and moisture from inside the building and protection against driving rain, etc., in accordance with the ventilated facades customary in construction.
  • the film used for the covering carrier itself can be a continuous, closed film, which therefore forms a barrier against the penetration of moisture by driving rain or by reverse diffusion into the building wall under unfavorable external climatic conditions.
  • the method according to the invention can also be carried out using a film with a large number of continuous openings or perforations, so that steam or steam can be evaporated or vented through these openings or perforations.
  • a film with a large number of continuous openings or perforations can be used in addition to the above-described attachment with passages in the region of the lower and / or upper edge.
  • the water vapor permeability of the film can suffice due to the water vapor permeability created by the passages or perforations in order to avoid the formation of moisture in the building wall.
