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 support layer consists of dense carrier material. This dense substrate ensures stable construction and mechanical strength of the base course.
  • the upper limit is, for example, the following values: 1200 kg / m 3 , 1100 kg / m 3 , 1050 kg / m 3 , 1000 kg / m 3 , 950 kg / m 3 , 900 kg / m 3 .
  • the lower limits are, for example, the following values: 400 kg / m 3 , 450 kg / m 3 , 500 kg / m 3 , 550 kg / m 3 , 600 kg / m 3 , 650 kg / m 3 , 700 kg / m 3 , 750 kg / m 3 , 800 kg / m 3 , 850 kg / m 3 .
  • the disclosure of this application includes the set of all intervals which consists of all possible combinations of the aforementioned upper and lower limits.
  • the disclosure of this application also includes all intervals that are only limited on one side, so that have only an upper or lower limit as indicated.
  • the support material is inorganic.
  • silica gel or silica
  • amorphous silica gel or amorphous silica
  • mineral foam or calcium silicate, glass wool, rock wool, fumed silica, airgel or the like.
  • fumed silica or also fumed silica
  • airgel are characterized by very low thermal conductivities less than 0.03 W / (m ⁇ K).
  • the heat-insulating material has a thermal conductivity ⁇ 0.025 W / (m ⁇ K), preferably ⁇ 0.02 W / (m ⁇ K), particularly preferably ⁇ 0.018 W / (m ⁇ K).
  • the abovementioned materials also make it possible to realize highly efficient, ie highly insulating, internal insulation elements with a small thickness, because the insulation layer has a maximum thickness of 30 mm, preferably not more than 25 mm, particularly preferably 20 mm.
  • a heat-insulating material of the insulating layer having a specific surface area of at least 100 m 2 / g (according to BET measuring method), preferably of at least 150 m 2 / g, particularly preferably of at least 200 m 2 / g (according to BET) , 250 m 2 / g, 300 m 2 / g or at least 350 m 2 / g used.
  • Pyrogenic silica has a specific surface area of about 200 m 2 / g +/- 10%.
  • the heat-insulating material has a density of at least 100 kg / m 3 , preferably at least 150 kg / m 3 , particularly preferably more than 200 or 250 kg / m 3 .
  • the heat-insulating material has a density of less than 400 kg / m 3 , preferably less than 300 kg / m 3 .
  • an interval is also specified, which is described by an upper and lower limit.
  • the upper limit is, for example, the following values: 400 kg / m 3 , 350 kg / m 3 , 300 kg / m 3 , 250 kg / m 3
  • the lower limits are, for example, the following values: 50 kg / m 3 , 100 kg / m 3 , 150 kg / m 3 , 200 kg / m 3 , 250 kg / m 3 , 300 kg / m 3
  • the disclosure of this application includes the set of all intervals which consists of all possible combinations of the aforementioned upper and lower limits.
  • the disclosure of this application also includes all intervals that are only limited on one side, so have only an upper or lower limit as indicated.
  • a heat-insulating material is selected with the lowest possible density, because this is favorable for a low heat conductivity.
  • a variant of the proposals therefore provides that the heat-insulating material has a density of less than 300 kg / m 3 , preferably less than 250 kg / m 3 , particularly preferably less than 200 or 150 kg / m 3 .
  • an inorganic material is provided for the vapor barrier or vapor barrier layer.
  • an inorganic material offers corresponding advantages, but the invention is not limited thereto. The invention nevertheless also encompasses polymer material intended for the vapor barrier or vapor barrier layer.
  • the material of the vapor barrier or vapor barrier layer metal for example a metal or aluminum foil or the like is provided.
  • the vapor barrier or vapor barrier layer may be used as a plastic film, e.g. is formed as a thermoplastic or elastomer, in particular as PTFE, polyethylene, Plexiglas or the like.
  • the use of a metal grid between the insulating layer and the storage layer and / or between the insulating layer and the supporting layer is proposed, whereby an electromagnetic shielding can be realized.
  • the metal grid is incorporated in the vapor barrier or vapor barrier layer or laminated on the storage layer, the insulating layer or the support layer.
  • the vapor barrier or vapor barrier layer is used as an adhesive layer, e.g. is designed as a mineral adhesive or cement-bonded system.
  • the Dampfsperr- or vapor barrier layer takes on an additional task, namely, it represents a mechanical bond between the support layer on the one hand and the insulating layer on the other hand. It has not been found that there are adhesive systems that, if they are applied sufficiently flat, also reliably prevent, but in any case reduce, through-diffusion of water vapor.
  • the mixture of the cement-bonded adhesive is optimized for optimal design of the vapor barrier or vapor barrier layer.
  • grading curves of the cement and the sand used are coordinated so that only a small number of chambers arise during the setting with water, which is then preferably filled by a powder plastic dispersion. Therefore, such a cement-based adhesive comprises a small amount (e.g., 0.5 to 4%) of plastic.
  • the invention comprises not only a four-layered structure, but also an at least five-layered structure in which the vapor barrier or vapor barrier layer (with its double function!) Is arranged between the insulating layer and the storage layer and / or between the insulating layer and the carrier layer.
  • the storage material is inorganic.
  • the storage material clay mineral in particular calcium silicate, phyllosilicates, vermiculite or mineral foam is provided.
  • the storage material is open to diffusion.
  • the storage material is porous, especially highly porous (more than 60%), or microporous and high capillarity, in particular capillary water absorption of at least 100 mass%, preferably at least 150 mass%, particularly preferably at least 200 or 250 mass%.
  • porous, or microporous reference is made to the above.
  • the capillary water absorption describes the ability of the storage material to absorb mass of water based on its own mass. Storage layers of calcium silicate (90% porosity) reaches a water absorption of 26 kg / m 2 .
  • the storage material is fungicidal, or the storage layer has a fungicidal coating.
  • Calcium silicate is characterized by a fungicidal property, as it forms a basic environment in contact with water that reduces, prevents or avoids the colonization of mold. At the same time, it is a material with high capillarity, that is, it is capable of absorbing and storing humidity largely from the ambient air and then releasing it again when needed.
  • the storage material has a density of> 150 kg / m 3 , preferably> 200 kg / m 3 , particularly preferably> 250 kg / m 3 .
  • the storage layer 4 Due to the moisture-regulating and fungicidal properties of a storage layer 4 formed in this way, growth of mold in the region of an interior-insulating element according to the invention is scarcely possible.
  • another material with moisture-regulating properties can also be used as the storage material; a fungicidal action could also be realized via a corresponding coating of the storage layer 4.
  • the storage layer has a thickness of about 20 mm.
  • the porous calcium silicate used has a density of about 285 kg / m 3 .
