The invention relates to a wooden material panel, in particular a wall, ceiling or floor panel, comprising a surface coating that is applied in at least some sections. Said coating contains at least one layer of plastic with a Shore hardness A of up to 90, preferably up to 80, in particular up to 65, preferably up to 50, especially between 20 and 60 and more specifically between 30 and 40. The invention also relates to a method for producing said wooden material panel.

The present invention relates to a method for producing a layered material, the layered material comprising a carrying layer and one or more further layers, wherein at least one of the further layers comprises thermally expandable microspheres, the method comprising attaching the layer comprising thermally expandable microspheres to another layer of the layered material, and thereafter expanding the microspheres. It also relates to a layered material comprising two or more layers of which one is a carrying layer, wherein at least one of the layers positioned under the carrying layer comprises expanded thermoplastic microspheres. It further relates to a composition for impregnating, or coating, a substrate, comprising thermally expandable microspheres.

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.

The invention relates to a sound proof composite system for space limiting surfaces comprising at least one coating layer (V) and one insulating layer (D) made of at least three additional layers. By using modified polyolefins having at least a required higher percentage of comonomers in order to obtain said properties, more precisely in the form of m-PE/ m-PP (VLDPE/ VLDPP) or a soft PVC sheet (I) as a core for the insulating layer (D) in combination with at least two external single or multi-layered sheets (A) containing a barrier substance (A1), it is possible to obtain densities of the insulation layer (D) of less than 1600 kg/m3 while ensuring good sound-proof qualities.
