Definitions

  • the invention relates to a heat and sound insulating composite element made of a rigid plastic foam, e.g. a polystyrene extruder foam (XPS) and a plasterboard.
  • a rigid plastic foam e.g. a polystyrene extruder foam (XPS) and a plasterboard.
  • XPS polystyrene extruder foam
  • Composite elements made of XPS and plasterboard are increasingly being used for the interior insulation of external walls in residential buildings. Such composite elements are characterized by excellent thermal insulation, but it has been shown that their sound insulation is not sufficient for many applications, that they can even lead to a deterioration of the sound insulation compared to an uninsulated wall. For example, the longitudinal sound conduction on walls, which is essentially responsible for the sound transmission between two neighboring rooms, can be higher when using the composite elements mentioned than with non-insulated walls.
  • a guideline for the influence of additional thermal insulation is the sound transmission from a transmission room into an adjacent reception room, guaranteed by the "insertion loss" according to DIN 4109.
  • the insertion loss is 28 dB (A).
  • the longitudinal sound conduction of the external wall is increased in comparison to the uninsulated version, i.e. the acoustic insulation is negatively affected.
  • the invention was therefore based on the object of improving the sound insulation in composite elements made of rigid plastic foam and plasterboard.
  • This object is achieved in that a layer of a flexible, open-cell thermoset foam is arranged between the rigid foam panels and the plasterboard panels.
  • the preferred rigid foam is polystyrene extruder foam. Compared to other foams, it is characterized by good rigidity and pressure resistance.
  • the density of the XPS plates is generally between 25 and 40 g ⁇ l ⁇ 1, their thickness preferably between 10 and 200 mm.
  • Polystyrene particle foam made of hard polyurethane foam and phenolic resin foam according to DIN 18 164.
  • Gypsum plasterboards C are also well known. They consist of a 5 to 20 mm thick plaster layer, which is laminated on both sides with cardboard. Gypsum plasterboards are also suitable as layer C.
  • the intermediate layer B consists of a flexible, open-cell foam.
  • Foams made from condensation resins based on melamine, urea and phenol formaldehyde are suitable, but also flexible polyurethane foams.
  • Elastic foams based on melamine resins, as are e.g. are described in EP-B 71 672. These foams generally have a specific weight of 5 to 100 g / l, in particular 8 to 20 g / l and a thickness of 10 to 100 mm, preferably 20 to 50 mm.
  • the figure shows a thermally insulated outer wall (1) with two interior spaces that are separated from each other by an inner wall (2).
  • a heat and sound insulating composite element which consists of three layers: an XPS board (3), an intermediate layer (4) made of an open-cell thermoset foam and a plasterboard board (5).
  • the thickness ratio of the foam layers A: B can vary within wide limits between 15: 1 and 1:15, it is preferably between 10: 1 and 1:10 and in particular between 4: 1 and 1: 4.
  • the individual layers are bonded to one another by conventional adhesives, for example based on polyurethanes or acrylates, which can optionally be adjusted elastically or can also be foamed.
  • the insertion loss according to DIN 4104 was 31 dB (A).
