  • a plaster layer applied to the thermal barrier coating or a ventilated protective facade made of wood or cement boards.
  • insulation boards made of a plastic foam material often results in the problem that the prepared from the insulation boards thermal insulation layer over a longer period alternately intense sunlight and strong cold may be exposed before attaching the weather protection, resulting in relatively strong thermal dimensional changes of the insulation boards and can lead to a detachment of the same from the substrate with glued insulation boards.
  • the insulation panels are processed in intense sunlight, there is also the problem that they can contract after gluing and it can come to open plate joints, which can form cold bridges.
  • very bright board materials e.g.
  • EPS expanded polystyrene

  • insulation boards with a base body made of a plastic foam material which have the same good properties in terms of thermal insulation and adhesion for cementitious adhesives or plasters such as open-pore uncoated insulation panels of a corresponding plastic foam material, but have a significantly lower thermal expansion behavior in direct sunlight. It is also possible to optimize these with respect to their reflection properties.
  • cut slabs can be made from one Carbon black, graphite or aluminum powder pigmented expanded polystyrene foam, which have excellent thermal insulation properties but tend to increased thermal expansion in intense, direct sunlight, on one of its two outer sides, ie on one of its two large surfaces, with a coating having a plurality of openings of white, extruded polystyrene (XPS) are provided, which can be significantly reduced their thermal length change, with virtually unchanged properties in terms of thermal insulation and adhesion to cementitious adhesives and plaster layers.
  • XPS extruded polystyrene

  • Such embodiments of the insulating panel have proven to be particularly advantageous and also have an increased flexural rigidity, which may be desirable depending on the use.
  • the second areas are formed by a plurality of individual spot coatings arranged on the body and spaced apart such that the coatings form a preferably uniform spot pattern on the surface of the body, the average area per punctiform coating is preferably less than 20 mm 2. It is also preferred that On average, more than four punctiform coatings are present per square centimeter of surface area.
  • Such embodiments of the insulation board have virtually the same flexural rigidity as uncoated plates of a corresponding plastic foam material, which may be advantageous depending on the application.
  • the coating is a material application preferably applied by printing, preferably paint application.
  • this material application by spraying e.g. of paint, with or without stencil, to apply to the open-pore outside of the body.
  • the coating consists of a thermoplastic plastic material, in particular of extruded polystyrene. Such materials can be easily connected by transient liquefaction with the open-pored surface of the body.
  • both the base body and the coating are made of thermoplastic materials and are fused together. This results in a solid, cohesive bond between the base body and the coating.
  • the coating is formed of a plastic material which consists of the same plastic base component as the plastic foam material of the base body, in particular of a polystyrene, polyurethane or polyisocyanurate. This results in optimum material compatibility and recyclability.
  • the main body of the insulating panel consists of an expanded or extruded polystyrene foam and the coating of an extruded polystyrene.
  • the coating consists of a material, preferably of a plastic material, which has a better reflectivity for infrared radiation than the plastic foam material of the base body.
  • the coating consists of a material, in particular of a plastic material, which is lighter than the plastic foam material of the base body.
  • the base body of the insulating panel of a pigmented plastic foam material preferably from a pigmented with soot particles, graphite particles or aluminum particles plastic foam material, preferably of expanded or extruded polystyrene.
  • plastic foam materials have very good thermal insulation properties.
  • a second aspect of the invention relates to the use of the insulating board according to the first aspect of the invention for the external thermal insulation of buildings. In such uses, the benefits of the invention are particularly evident.
  • a third aspect of the invention relates to a method for producing an insulating board according to the first aspect of the invention.
  • a plate-shaped base body made of a plastic foam material is provided, in which at least that outer surface, which is disposed away from the building when the insulation board to be formed with this base body is intended to be formed, has an open-pored surface.
  • this open-pored outer surface is provided substantially over its entire planar extent with a continuous coating having a plurality of regular or irregular openings or with a plurality of individual, spaced-apart punctiform coatings, such that the outer surface thus coated has a surface in which open-pore regions formed by the outer surface of the main body alternate with open-pored and / or closed-pore regions formed by the coating.
  • the inventive method makes it possible for the first time to produce insulating panels of a plastic foam material, which are comparable in thermal insulation and / or reflection properties with respect to their thermal insulation properties and their adhesive strength for cementitious adhesives or plasters with insulating panels, which are formed exclusively of this plastic foam material Sunshine clearly different from these.
  • the coating takes place under or by printing a material, preferably a paint, on the open-pored outer surface of the body. It is also intended to apply this material by spraying, with or without stencil.
  • a material preferably a paint
  • the coating takes place by contacting or by contacting a thermoplastic material in the at least partially molten state with the open-pored outer surface of the base body, resulting in the advantage that liquid material can penetrate into the open-pored surface of the body and after solidification of the same gives a good bond between the coating and the base body.
  • the coating takes place with a melting or by melting a film, preferably of expanded polystyrene (XPS), on the open-pore outer surface of the body.
  • XPS expanded polystyrene
  • the coating takes place by melting or by melting individual plastic particles previously arranged on the open-pored outer surface of the insulating board, so that a multiplicity of individual, spaced-apart spot coatings are formed on the open-pored outer surface.

As a result, these are materially interconnected.
  • the coating is formed from a plastic material which is formed from the same plastic base component as the plastic foam material of the main body, preferably from a polystyrene, polyurethane or polyisocyanurate. These materials are well established in the field of building exterior thermal insulation and there is also the advantage of good material compatibility and recyclability.
  • a base body of a pigmented, expanded or extruded Polystyrene foam provided and the coating formed from an extruded polystyrene.
  • the coating is formed of a material, in particular of a plastic material, which has a better reflectivity for infrared radiation than the plastic foam material of the base body, so that the heating of the plastic foam material in direct sunlight and thus a thermal expansion of the inventive Insulating board opposite an insulation board, which consists exclusively of the plastic foam material of the body, is significantly reduced.
  • the coating is formed of a material, in particular of a plastic material, which is lighter than the plastic foam material of the base body.
