Definitions

  • the present invention relates to a wood-based panel with reduced acoustic emission according to claim 1 and a method for its production according to claim 14.
  • Laminate flooring which can be produced from wood-based panels or floor panels, has been marketed for about 25 years with a focus on Central Europe.
  • the market share of laminate flooring in the total floor market is now more than 10% in individual countries.
  • the focus of the use then as now in the non-commercial area for almost all domestic applications.
  • a particular advantage of laminate flooring is that it can be easily installed using floor panels, without these panels must be glued together.
  • laminate floors are becoming increasingly popular, the product still suffers from certain shortcomings that are repeatedly highlighted by users.
  • the product laminate flooring is predominantly made of wood and is therefore moisture-sensitive or not dimensionally stable in the event of changing air humidity. For this reason, use of laminate flooring e.g. to classify as critical in humid areas.
  • Laminate floors are mainly laid floating using individual panels, whereby a connection between the individual panels is effected in the laying plane, but with no contact with the underlying ground layer.
  • audible sound waves are generated. These sound waves are on the one hand audible as Begehschall in the same room in which the excited laminate floor is, or are audible as impact sound in underlying rooms. The buyer of the product perceives the room / walking noise as particularly negative.
  • the order quantities of the synthetic rubber on the back of the floor panels are at least 250 g / m 2 , whereby the product is considerably more expensive.
