Abstract: A floor system and a floor of a plurality of floor panels of support boards with at least one coated surface, which have a decoration and locking devices on the support board edges, which devices make it possible to connect two or more floor panels to one another and prevent a displacement of the floor panels with respect to one another in the laying plane and/or perpendicular thereto. A first part of the floor panels has support boards of wood or a woodbased material and a second part of the floor panels has support boards of a plastic.

Abstract: The invention relates to a sound-insulating board, in particular a footfall insulating board for laminate floors or similar applications. The sound-insulating board is distinguished by a continuous transition of its density from the one large-area side to the other large-area side of the board and comprises a mixture of unglued wood fibers, a binder and/or supporting fibers and a mixed plastic, such as arises from the dual system during the recovery of plastic parts. The sound-insulating boards according to the invention are used as the underside of laminate floors, but can also be used as an underlay board, to which the floor covering is then applied. A further use for the footfall insulating boards according to the invention, in particular with thicknesses of more than 8 mm, results in dry construction as a floor-leveling board on large-area structural elements.

Abstract: The invention relates to wood fiber insulating material boards and mats, in which the wood fibers and the binder fibers are aligned three-dimensionally. The fleece of wood fibers and binder fibers can alternatively have synthetic resin granules scattered on it. Likewise, a woven fabric or a film can be applied to one or both sides. The product obtained in this way is heated in a heating/cooling oven, calibrated and/or compacted to the desired final thickness. The wood fiber insulating boards and mats according to the invention have thicknesses from 3 to 350 mm and bulk densities of 20 to 300 kg/m3. They possess good transverse tensile strength and an improved compressive rigidity.

Abstract: The invention relates to the production of wood fiber insulating material boards and mats, in which the wood fibers are mixed with binder fibers, the fiber mixture is blown out of a storage container onto a first transport belt with a three-dimensional alignment of the fibers. The fleece obtained can alternatively have synthetic resin granules scattered on it. The fleece obtained is comminuted and, after being mixed once more, is blown onto a second transport belt in the desired thickness. After that, a woven fabric or film can be applied to one or both sides. The product obtained in this way is transferred to an oven belt and supplied to a heating/cooling oven. Following heating to temperatures of 130 to 200° C. by means of air blown in, softening of the binder fibers and of the synthetic resin granules takes place. As a result, an intimate connection of the wood fibers and, at the same time, attachment of the woven fabrics or films applied to the mat takes place.

Abstract: The invention relates to an insulation material board composed of a wood material/binder fiber mixture and to a method for producing an insulation material board, in which an additive (3, 4) with a thermally resistant core (4) and with a thermally activatable coating (3) is added to the mixture, and the thermally activatable coating (3) is activated by the supply of heat.
