Definitions

  • the invention relates to an internal insulation element consisting of several layers.
  • thermal insulation of buildings from the outside becomes increasingly important in times of high energy costs.
  • the first choice in the thermal insulation of buildings is the external insulation. In some cases, however, such insulation outside the masonry is not possible. This can for example be the case with listed buildings or if an external insulation for technical reasons is not possible or not affordable. In such cases, there is the possibility of internal insulation. This material is applied with good thermal insulation properties from the inside to the masonry.
  • a known solution against this condensation on the inside of the wall is the application of a so-called vapor barrier on the inside of the inner insulation.
  • a so-called vapor barrier on the inside of the inner insulation.
  • the material used for the insulating layer is the use of polystyrene, especially in the generic mecanicdämm instituten widely known. This material is characterized by favorable insulation properties at a relatively low price. However, this material causes problems in fire protection, since it burns, and it also prepares when recycling the generic réelledämmimplantation problems because they actually only used thermally can be. Although it is also known to use used Styrofoam as additives in the production of new polystyrene plates and the like, but then the starting material must be sufficiently pure, which is not always possible with multi-layer insulation elements.
  • an internal insulation element is understood to be an insulation element that is used or installed in the interior or in the interior of a building. It can be realized for example as a plate or plate-shaped element, or also have other geometric shapes. It is preferably used for insulation purposes where condensation can occur, which can then lead to corresponding impairments or damage.
  • the interior insulation element according to the invention for example Also, with appropriate layer structure or arrangement, dam a hot water leading line to the interior.
  • isseendämmimplantations is thus not limited to the inner dams of the (cold) house outer wall to see.
  • the whistle of the invention is that an existing of different layers réelledämmelement is proposed, which consists predominantly of inorganic material, ie of mineral material that is not combustible.
  • the invention also includes solutions which allow a small proportion by weight of polymers, ie organic material, but which is so low that it is not questionable in case of fire.
  • an inner damping element which has a multilayer construction, wherein each layer is designed to be optimized for at least one specific function. This happens on the one hand by the choice of the material of the respective layer and on the other hand by the special layer structure.
  • the inner insulation element according to the invention has a multilayer construction.
  • the basis of the mechanical strength of the réelledämmimplantations is a support layer.
  • This support layer may have thermal insulation properties, but the focus here is on the mechanical strength, for which poorer insulation properties are taken into account at this point.
  • the supporting layer is thus the basis of the further construction of the inner lining element and acts as a supporting basic framework for the following layers.
  • the insulating layer is formed according to the invention by a material with very good properties for thermal insulation.
  • the heat-insulating material of the insulating layer has a thermal conductivity of less than 0.03 W / (mx K).
  • the thickness of the insulating layer can be chosen low, and the precious room of the room is not overly due to the shoring reduced the êtendämmelement invention. Due to the presence of the supporting layer, a thin insulating layer also does not have a negative effect on the strength of the inner insulating element according to the invention.
  • the storage layer Towards the interior of the insulation element is the storage layer.
  • This storage layer consists of a diffusion-open material.
  • the thermal insulation properties of the storage layer are lower than those of the insulating layer. Nevertheless, the storage layer also contributes to the thermal insulation between interior and exterior.
  • the main function of the storage layer is the humidity regulation of the interior or living space.
  • the storage layer absorbs humidity that accumulates, for example, when showering, cooking or in the presence of many people in the room and stores the moisture contained therein. In times of low humidity indoors, such as e.g. In the heating period is often the case, the storage layer this moisture back to the interior and thus provides a compensating for pleasant humidity.
  • the inner insulation element according to the invention also has a vapor barrier or vapor barrier layer.
  • This layer has a high water vapor diffusion resistance, making it almost close to moisture.
  • the task of the vapor barrier or vapor barrier layer is to protect the highly insulating insulating layer from condensation.
  • this vapor barrier or vapor barrier layer is disposed between the insulating layer and the storage layer and / or between the insulating layer (2) and the carrier layer (1).
  • humid indoor air can indeed penetrate into the storage layer, which is also desirable, but not up to the insulating layer.
  • the vapor barrier or vapor barrier layer also (or only) between the insulating layer (2) and the support layer (1) is arranged.
  • the inner insulation element consists exclusively of inorganic material.
  • the positive property of incombustibility of the inner dam element is combined with easy recycling since the inner damming element made of mineral materials can be easily worked up in recycling and used as an aggregate in the construction industry and so on.
  • the support layer consists of dense carrier material. This dense substrate ensures stable construction and mechanical strength of the base course.
  • the mechanical strength of the support layer is higher than the mechanical strength of the storage layer.

  • the support material has a density ⁇ 1200 kg / m 3 , in particular ⁇ 1000 kg / m 3 .
  • the support material must have sufficient rigidity, ie a minimum density, since the support layer is responsible for the mechanical stability of the inner insulation element. On the other hand, the density must not be too high, because then the total weight of the réelledämmimplantations becomes unfavorable.
  • an interval is also specified, which is described by an upper and lower limit.

However, moisture occurring at this point does not remain there but is released back into the interior of the room due to the diffusion-open properties of the storage layer 4.
