Definitions

  • the invention relates to an insulation element according to the preamble of claim 1, a use of the insulation element and a method for producing a preferred embodiment of the insulation element.
  • I O DE-19815202-A1 describes an insulation element which is provided in particular as a heat insulation plate for exterior facades of houses.
  • This insulation element comprises a heat-insulating inner body and a sheathing made of rigid polystyrene foam which surrounds and connects this inner body.
  • the inner body can be made of rigid phenolic foam, rigid polyurethane foam or
  • a disadvantage of this and other known insulation elements is that they have too high a thermal conductivity for a large number of applications, so that an intolerable thickness of the insulation element is required to achieve a predetermined heat insulation.
  • the use of underfloor heating in old buildings is often only possible when considerable heat transmission losses are incurred against unheated zones, since an insufficiently thick thermal insulation layer can be installed due to the limited space available.
  • the object of the invention is to improve an insulation element of the type mentioned in the introduction so that it has a lower thermal conductivity.
  • a further object of the invention is to specify a use of the insulation element according to the invention and a manufacturing method for a preferred embodiment of the insulation element.
  • the inner body contains an insulating element which is formed from a core part which is under vacuum, this inner body has a substantially improved thermal insulation ability compared to the inner bodies described in DE-19815202-A1.
  • the insulation element according to the invention is suitable, for example, for floor insulation, for interior and exterior insulation of external walls, for steep and flat roof renovation, and for installation, for example, in wall elements, window frame extensions and parapets, and exterior doors.
  • the insulation element according to the invention can be used instead of an externally identical insulation element according to the prior art.
  • it By using it as a built-in element, for example, in a pre-existing heat-insulating arrangement formed from one or more known insulation elements, improved heat-insulation behavior can be achieved while maintaining the specified dimensions.
  • an outer surface of the insulating element is coated with an adhesive, then surrounds the insulating element with a plastic granulate and then the latter is expanded into a foamed plastic in an expansion time period which is shorter than a curing time period required for the curing of the adhesive , an insulation element with a well-fitting, detachable casing can be made from a foamed plastic.
  • the casing is formed from a heat-insulating material, which results in an improved thermal insulation ability of the entire insulation element.
  • Particularly advantageous materials for the casing are defined in claims 4 to 7.
  • Claim 10 defines a preferred embodiment of the manufacturing process, according to which granules formed from expandable polystyrene are used as plastic granules.
  • FIG. 1 shows an insulation element, with a partially cut jacket, in a perspective view
  • Figure 2 shows the inner body of the insulation element of Figure 1, in a perspective view
  • Figure 3 shows the insulation element of Figure 1, in a cross-sectional view.
  • the insulation element shown in FIGS. 1 and 3 has a heat-insulating inner body 2 and a sheathing 4 surrounding it and connected to it.
  • the inner body 2 contains an insulation element 6 which is known per se and which contains a microporous core part 10 which is welded into a highly gas-tight film 8, for example an aluminum composite film, and which is under vacuum with a pressure of approximately 0.1 mbar.
  • the core part 10 is made from an open-cell, extruded polystyrene or from pyrogenic pine Seisaure formed
  • Such dam elements are available in different dimensions and have a thermal conductivity of 0.004 to 0.008 Wm 1 K 1 , which is significantly lower than that of conventional dam materials.
  • the thermal conductivity of expanded polystyrene is approximately 0.034 to 0.040 Wm 1 K 1 and that of Polyurethane approximately 0.024 to 0.028 Wm 1 K 1
  • the sheathing 4 serves to protect the film 8 and, in particular, is intended to prevent the formation of leaks as a result of mechanical influences, since the penetration of air into the dam element 6 causes a considerable increase in the thermal conductivity and accordingly would result in a substantial loss of the desired heat insulation capability
  • the materials for the sheathing 4 include, for example, rock wool, glass wool, foam glass, cork, lightweight panels made of wood wool, wood fiber boards and other heat-insulating materials. Foamed plastics such as expanded polystyrene or polyurethane are particularly advantageous be provided.
  • the sheathing 4 is advantageously glued to an outer surface of the dam element 6
  • the film 8 has a plurality of weld seams 12, which form a vacuum-tight closure of the dam element 6.
  • External film sections 14 consist of parts of the film 8 which, with respect to an associated weld seam 12, lie on one of the evacuated area of the dam element 6 are facing away
  • the external film areas 14 are placed in a flat on the outer surface before attaching the casing 4 bring it into an overlying position to avoid a good fit of the casing and the formation of bulge-like bumps.
  • the insulation element Depending on the type of sheathing, there are various methods for producing the insulation element. If the casing 4 consists of prefabricated parts, the latter are arranged around the insulation element 6. Cohesion of the individual parts is achieved, for example, in that the casing parts and / or the insulation element are coated with an adhesive at suitable contact points before the insulation element is assembled. Instead of gluing, however, local fusing of the sheathing parts with one another and / or with an outer layer of the film 8 can also be used.
  • the casing 4 is foamed around the insulating element 6, for example by building up a layer with a thickness of 7 to 10 mm.
  • Particularly good results are achieved by first covering the insulating element 6 with an adhesive, then surrounding the insulating element 6 with a plastic granulate and then expanding the latter to a foamed plastic by supplying heat, for example with steam.
  • an adhesive must be selected that requires a curing time t for curing that is longer than an expansion time t £ required for the expansion of the plastic. This ensures that the plastic granulate material remains movable relative to the insulation element during foaming and can thus adapt to the shape of the insulation element.
  • Expanded polystyrene as the material of the sheathing 4 has the advantage over other materials such as polyurethane, for example, that excessive foaming does not occur during foaming, and thus deformation or melting of the core material 10 located in the insulating element 6 or its enveloping film 8 is avoided.
  • Another advantage of expanded polystyrene is that conventional materials for plastering and plaster layers in construction are matched to polystyrene. This means that an insulation element with a jacket made of expanded polystyrene can be provided with a directly applied layer of plaster. This results in particular in the possibility to use the insulation element instead of an externally identical, conventional insulation element, for example instead of a homogeneously formed standard insulation element.
