Definitions

  • the present invention relates to a plate-shaped thermal insulation composite. Furthermore, the invention relates to a thermal insulation composite area, in particular thermal insulation panel area, comprising thermal insulation composite or thermal insulation boards, as well as methods for producing thermal insulation joints, in particular thermal insulation panels. Moreover, the invention relates to the use of thermal insulation joints, in particular thermal insulation panels, for the thermal insulation of buildings.
  • Vapor-proof internal insulation has the disadvantage that it can easily be damaged in small repairs or installations and no longer fulfill their task.
  • the moisture balance of a building exterior wall, in particular impact rain wall can be noticeably affected by an internal insulation to the detriment. Because a building facade absorbs water in the course of a year, which causes no damage as long as the damp masonry in the summer can dry inside. After attaching a vapor-tight inner insulation this is no longer possible. Moisture accumulates behind the insulation material and the masonry becomes continuously wet. This increases the risk of mildew and the risk of frost damage. Structural damage can no longer be ruled out.
  • Capillary-active internal insulation does not use a vapor barrier.
  • the above-described disadvantages occur in such internal insulation regularly not or only attenuated, depending on the quality of the inner insulation.
  • homogeneous open-pore mineral plates are used for capillary-active internal insulation. These include calcium silicate boards such as the commercially available product Calsitherm, mineral insulating materials which contain perlite as a filler, for example the product Tectem, and the aerated concrete Multipor. In this context, also on the DE 197 23 426 C1 and the DE 10 2010 005 361 A1 directed.
  • the essential common feature of these insulation boards is that the homogeneous material must simultaneously fulfill the two functions of thermal insulation and capillary conductivity, thus it is inevitably only a compromise dar.
  • These plates generally have a density of about 120 to 300 kg / m 3 at a Thermal conductivity (dry) from approx. 0.045 to 0.065 W / mK.
  • capillary-active interior insulation slabs of blown cork as in the DE 10 2007 025303 A1 described, used, which have been filled through the entire plate cavities under vacuum with modified clay. While the first material is responsible for the thermal insulation (cork), the other material (clay) is used for capillary conductivity.
  • the bulk density of the filled cork plate is 120 to 150 kg / m 3 with a thermal conductivity (dry) between 0.04 to 0.06 W / mK.
  • EP 2 447 431 A2 serves a plate of expanded polystyrene whose individual prefoamed balls are still largely round and have adopted little of the usual polyhedra in polystyrene plates, as responsible for the thermal insulation component.
  • This plate is traversed by continuous and partially connected cavities, which, similar to in DE 10 2007 025 303 A1 were filled under vacuum with a lime / cement-based composition as a capillary-conductive material.
  • An essential feature of the above-described embodiment of insulation boards is that in Basically, two individual anisotropic scaffolds, one in charge of thermal insulation and one for capillary conductivity, are placed one inside the other. As a result, there is no preferred direction for either the heat or the capillary.
  • insulation boards such as EP 86 681 B1 can be seen, also have a checkerboard-like arranged Dämmplattenabête, which are connected via capillary-active cuboid webs.
  • Insulating boards with cuboidal capillary conductive webs are also found in the DE 10 2010 044 791 A1 and DE 10 2010 044 789 A1 disclosed.
  • the webs are made of calcium silicate, the insulation boards are vacuum insulation panels and aluminum-foamed rigid polyurethane foam.
  • Insulating materials as in the DE 197 23 426 C1 and DE 10 2010 005 361 A1 disclosed, are relatively heavy and have significantly poorer insulation properties in the dry state than the usual insulation for the outer insulation (such as EPS, PU or PF). Due to their high density and the required due to the only moderate thermal insulation higher plate thickness for a comparable energy savings and resource consumption in the above-mentioned insulation materials is high. In addition, these insulating materials are generally hardly mechanically loadable, which is reflected in the often small plate dimensions that must be applied in practice. It is not uncommon in the creation of a insulated inner wall to breakouts and breaks, especially on plate corners, which are then often filled with mortar, but which has no heat-insulating properties, thus representing a thermal bridge. Due to the manufacturing process, cracks and bubbles can not be ruled out over a large area. In these areas, the capillary is interrupted.
  • Insulating materials as in the WO 92/10624 generally do not use small amounts of capillary conductive material. This gives away valuable space for the heat-insulating component. Also, the production of these insulation materials is often not trivial. In addition, the mechanical complexity is high. Due to the required vacuum, the systems can fill only small sized blocks with the capillary active material.
  • the DE 102 46 587 A1 refers to a stiffened mineral wool plate with dimensions: height from 10mm to 200mm (z-direction), width from 625mm to 2000mm (x-direction) and length from 1000mm to infinitely long (y-direction).
  • the stiffened plate is cut into strips (y / z or x / z plane).
  • Glue gypsum, cement mortar, plastic, resin or bituminous glue
  • the present invention was therefore based on the object to provide insulation materials that overcome the disadvantages of the prior art and in particular allow a building interior insulation, which is structurally easy to implement and at the same time minimizes the risk of thermal bridges or completely excludes, and although without relying on a vapor barrier.
