Abstract (en)
[origin: WO02055811A1] The invention relates to a sound insulation mat for floor coverings, particularly for parquet floors and laminated floors, comprising a mat layer that has a mat top side and a mater underside, whereby the mat layer contains natural raw material fibers, at least one bonding agent and high-density particles. The aim of the invention is to provide a sound insulation mat and a method for producing the same with which both the footstep sound as well as the room sound insulation are improved. To this end, the invention provides that the high-density particles are arranged in an inhomogeneously distributed manner inside the mat layer whereby creating a density distribution that increases from the mat underside to the mat top side. The invention also relates to a method for producing a sound insulation mat according to which: a mixture consisting of natural raw material fibers and of at least one bonding agent is produced; a loose mat is formed from the mixture; high-density particles are arranged in a distributed manner on the mat top side, whereby subsequently penetrating into the mat, and; the mat is subsequently compacted.
