Definitions

  • the invention relates to a wall covering intended to be permanently applied to a house interior wall to prevent mold growth on a cool wall area of the house interior wall.
  • the invention also relates to the intended arrangement of such a wall covering on the inside wall of the house, the use of such a wall covering for application to the inside wall of the house and a method for applying the wall covering to the inside wall of the house to prevent mold growth on a cool wall area of the inside wall of the house.
  • the object of the invention is to provide a wall covering that can prevent mold growth on cool areas of house interior walls.
  • a wall covering which is formed by a thermally conductive fleece, fabric or a wallpaper coating, consists of a material with a thermal conductivity of more than 200 W/m ⁇ K, is non-electric and is intended for this purpose to be applied so flatly to the inside wall of the house that it covers the cool wall area as well as a warmer wall area adjacent to the cool wall area and thereby absorbs heat from the warmer wall area and conducts it to the colder wall area in order to reduce the surface temperature of the cool wall area by 1-3° to increase C.
  • this wall covering is consequently the high natural thermal conductivity of the material from which it is formed, exploited to a wall area that is warmer than the cooler wall area at risk of mold to absorb heat and conduct it to the cooler wall area, so that the temperature in the cooler area rises by 1 to 3°C and mold can therefore no longer form.
  • the wall covering is in direct, planar contact with the masonry of the inside wall of the house.
  • the heat absorbed by the wall covering in the warmer wall area comes mainly from the masonry of the warmer wall area. However, some of the heat also comes from the room air in front of the warm wall area, which gives off its heat to the masonry and also transfers it to the wall covering.
  • the thermal pad is not electrical, i.e. no current flows through it and therefore does not serve as an active heater. It therefore does not require connection by an electrician, has no power consumption, is maintenance-free and has a long service life.
  • the cooler wall area is, for example, in room corners or in the area of window reveals, while the warmer wall area is a middle area of the house interior wall.
  • the material from which the wall covering is made can be aluminium, copper or carbon (graphite), as these materials have very good thermal conductivity.
  • the wall covering is designed as a fleece, this can have a thickness of between 0.05 mm and 0.2 mm, for example.
  • the fleece preferably consists of aluminum, copper and/or carbon fibers (graphite fibers).
  • the wall covering is designed as a fabric, this can be formed, for example, by wires with a diameter between 0.05 mm and 0.3 mm.
  • the fabric can have a mesh size between 0.2mm and 1.5mm. It can therefore be regarded as a fine-meshed fabric.
  • the fabric has a basis weight of 100 to 200 g/m 2 .
  • this coating can have an application weight of between 150 g/m 2 and 250 g/m 2 .
  • the wall covering is also conceivable in the variant of the wall covering as a woven fabric or fleece that the wall covering is applied to a carrier material in order to improve its processability.
  • the carrier material can consist of a rollable material, for example paper, a textile or a fleece, with the wall covering being laminated onto the rear side of the carrier material intended to face the interior wall of the house.
  • a carrier material made of fleece can consist of fibers made of glass, cellulose or polyester or can contain these materials.
  • the carrier material On its outside facing the interior, the carrier material can have a layer of a foamed material.
  • the carrier material can be an essentially dimensionally stable insulating board, in particular made of a mineral material such as expanded glass, perlite or calcium silicate.
  • the wall covering preferably has an air layer thickness equivalent to water vapor diffusion (s d value) of less than 0.5 m.
  • the invention also relates to the use of a wall covering with one or more of the aforementioned features for permanent application to a house interior wall to prevent mold growth on a cool wall area of the house interior wall in such a way that it covers both the cool wall area and a warmer wall area adjacent to the cool wall area covered and thus absorbs heat from the warmer wall area and conducts it to the colder wall area in order to increase the surface temperature of the cool wall area by 1-3°C.
  • the invention also relates to an arrangement of a wall covering with one or more of the aforementioned features and an interior wall of a house, on which the wall covering is applied to prevent mold growth on a cool wall area in such a way that it uses the cool wall area as a also covers a warmer wall area adjacent to the cool wall area and thereby absorbs heat from the warmer wall area and conducts it to the colder wall area in order to increase the surface temperature of the cool wall area by 1-3°C.
  • the wall covering is in the form of the fabric, it can be embedded in a layer of mineral adhesive, e.g. a cement adhesive, which is applied to the inside wall of the house.
  • mineral adhesive e.g. a cement adhesive
  • the wall covering is in the form of a fleece or a backing material coating, it can be applied to a layer of dispersion adhesive that is applied to the inside wall of the house.
  • the invention also relates to a method for applying a wall covering with one or more of the aforementioned features to a house interior wall to prevent mold growth on a cool wall area of the house interior wall, the wall covering being applied in such a way that it covers the cool wall area as well as one on the cool wall area covers the adjacent warmer wall area and thus absorbs heat from the warmer wall area and conducts it to the colder wall area in order to increase the surface temperature of the cool wall area by 1-3°C.
  • a mineral adhesive for example a cement adhesive
  • a cement adhesive can be applied to the inside wall of the house and the wall covering can then be embedded in the adhesive so that it is in full-surface contact with the masonry.
  • the cement adhesive can be applied, for example, with a notched trowel, also known as a notched spatula or notched trowel, using what is known as the comb bed method. This has the advantage that the adhesive is applied and distributed particularly evenly.
  • the Notched trowel consists of a plate made of metal or plastic and a handle, the plate having at least one edge along which teeth are arranged in the form of triangular projections (pointed teeth) or square projections (square teeth).
  • the wall covering or the fabric is placed in the adhesive. This pushes the adhesive through the machine of the fabric.
  • the adhesive is then smoothed, for example with a smoothing spatula, also known as a smoothing trowel.
  • the wall covering is thus completely embedded in the mineral adhesive.
  • a dispersion adhesive can be applied to the inside wall of the house and the wall covering can then be glued to the adhesive.
  • the dispersion adhesive can also be applied with a notched trowel (notched spatula or notched trowel) using the so-called comb bed method. This variant is very easy to carry out and is therefore particularly suitable for do-it-yourselfers.
  • the fleece or carrier material can then be painted over if necessary.
  • the wall covering is optimally processed if it is provided as rolled goods, i.e. in a rolled-up state. This prevents kinks and makes transport easier.
  • FIG 1 shows a wall covering 1 according to the invention for permanent application to a house interior wall 2a to prevent mold growth on a cool wall area 5 of the house interior wall, which is formed only by a thermally conductive fabric 1.
  • the fabric 1 consists of aluminum, copper or carbon wires with a diameter between 0.05 mm and 0.3 mm and a mesh size between 0.2 mm and 1.5 mm. It has a thermal conductivity of more than 200W/m ⁇ K.
  • the wall covering can also be formed from ribbons.
  • FIG 2 shows an arrangement of this wall covering 1 on the inside 2a of a house wall 2.
  • the wall covering 1 is intended to be so flat on the inside wall 2a of the house that it has a cool wall area 5, which is present here in the wall corner, and a warmer area adjacent to the cool wall area 5
  • Wall area 4 which is present here approximately in the central area of wall 2, covers.
  • the wall covering 1 or the fabric is embedded in a mineral adhesive applied to the wall 2, for example a cement adhesive, so that it penetrates the mesh.
  • the wall covering 1 is thus in direct contact with the masonry. It absorbs heat 4 from the warmer wall area and conducts it to the colder wall area 5 in order to increase the surface temperature of the cool wall area 5 by 1-3°C. This avoids or at least minimizes the risk of mold formation. This is solely due to the natural thermal conductivity of the material and the structure of the wall covering 1. Because it is not electrical and therefore does not form an electrical heater.
  • the wall covering 1 can be a fleece that is applied directly to a dispersion adhesive applied to the wall 2 .
  • the fleece can have a thickness of between 0.05mm and 0.2mm and have fibers made of aluminium, copper and/or carbon.
  • a carrier material can be present on the inner and/or outer surface of the wall covering 1 for its stabilization and easier processing, for example made of a layer of paper, a fleece (e.g. painter's fleece) or a foamed material (such as a thin layer of cellular rubber, styrofoam or polyurethane).
  • the carrier material can be glued or laminated onto the wall covering 1, which can be a woven or nonwoven fabric.
  • a fleece as the carrier material, its fibers - in contrast to the thermally conductive fibers of the wall covering fleece - consist of cellulose or glass.
  • Such a wall covering can be easily glued to the inner surface 2a of the building wall 2a. If the surface of the wall covering 1 facing the room 6 has a carrier material in the form of a paper layer or a non-woven fabric that is glued on, the wall covering 1 can easily be covered or painted over with wallpaper.
  • the surface of the wall covering 1 facing the room 6 has an outer fleece 8 made of cellulose or glass (painter's fleece) that can be painted over and/or papered over, and the surface of the wall covering 1 facing the wall 2 has an inner fleece 9, e.g. made of polyester, so that the wall covering 1, here in the form of a fabric or lattice, is arranged between the inner and outer fleece 3, 4 and is fastened with adhesive.
  • This layer arrangement then forms a composite material 7 overall.
  • a foamed material can also be used, e.g. B. a thin layer of cellular rubber, polystyrene or polyurethane.
  • a carrier material in the form of a mineral insulating board 10 is arranged, in particular glued, on the surface of the wall covering 1 facing the wall 2 .
  • the insulation board can consist of expanded glass, perlite or calcium silicate, for example.
