A building panel including a water resistant core including thermoplastic material and a surface layer including thermosetting resins. Also, production methods to form a board material with a dry blend of thermoplastic particles in powder form and fillers in powder form and to apply a surface layer with a hot-hot lamination process to a core including such board material.

Provided is a panel including at least one first coupling part. The first coupling part includes an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove formed in between the upward tongue and the upward flank. The side of the upward tongue facing towards the upward flank is the inside of the upward tongue and the side of the upward tongue facing away from the upward flank is the outside of the upward tongue. At least a part of an upper side of the upward tongue is inclined relative to the plane of the panel, such that the upper side of the upward tongue includes a highest point. The upward tongue has a width, wherein the highest point of the upward tongue is arranged less than 50% of the width from the outside of the upward tongue.

A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.

A panel having a core, a top side, a underside, a first edge pair and a second edge pair. The first edge pair has a groove profile at a panel edge and a complementary tongue profile at the opposite panel edge, which cooperate in positively locking relationship so that movement of locked panels away from each other in the plane of the panels is opposed. At its opposite panel edges the second edge pair has a receiving hook and a complementary arresting hook. The arresting hook can be assembled to the receiving hook by a joining movement in a direction perpendicular to the panel plane. The receiving hook has a holding groove for a separate locking element for a vertical locking action. At a corner of the panel the tongue edge of the first edge pair comes together with the receiving hook. The holding groove provided on the receiving hook of the second edge pair for the locking element has an upper groove wall with a spacing from the top side that is greater than the spacing between the panel top side and the tongue top side of the tongue profile of the first edge pair.

Decorative panel, in particular a floor panel, ceiling panel or wall panel, including a core layer having an upper side and a lower side, a decorative top layer connected to said upper side of the core layer, a first panel side edge including a first coupling profile, and a second panel side edge including a second coupling profile designed to interconnect with a first coupling profile of a second, identical panel, both in horizontal direction and in vertical direction. The core layer includes a layer of foam concrete which is constituted by a matrix of concrete material in which air pockets in the form of cells are present.

A floor panel for forming a floor covering, wherein this floor panel is at least composed of a substrate; wherein the floor panel, on at least one pair of opposite edges, comprises coupling parts, which coupling parts allow that two of such floor panels can be coupled to each other by means of a downward movement of one floor panel in respect to the other floor panel; wherein these coupling parts, in the coupled condition of two of such floor panels, form a first locking system, which effects a locking in a first direction perpendicular to the plane of the floor panels, and form a second locking system, which effects a locking in a second direction perpendicular to the edges and in the plane of the floor panels.

A floor panel arranged to be installed according to the fold-down principle, with a first pair and a second pair of edges. The second pair of edges coupling parts are arranged to be coupled to each other by a downward movement with two contact zones at opposite sides of a male part which fits into a female part. The ratio between the horizontal distance between the middle of the first contact zone and the middle of the second contact zone, and the vertical distance between the middle of the first contact zone and the middle of the second contact zone is more than 5, and/or wherein well-defined support points are applied.

A set of mutually lockable panels comprises a first panel having an edge including a male part and a second panel having an edge including a female part for receiving the male part of the first panel in unlocked condition of the panels. The male part has an outer side which, in locked condition of the panels, is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface. The female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel and an actuator for rotating the locking member from its unlocked condition to a locked condition of the panels.

The floor or wall panel has a substrate and a top layer applied thereon. The substrate consists mainly of a mineral material. The panel is provided, on at least two opposite edges, with coupling means that allow two such panels to be coupled together at the respective edges, wherein in the coupled state there is locking in the vertical direction perpendicular to the plane of the coupled panels and in the horizontal direction perpendicular to the coupled edges and in the plane of the coupled panels.

Floorboards which have a core and a surface layer and are provided with decorative joint edges which are formed by removing the surface layer. A method for making a floorboard, or a floor element that is to be divided into at least two floorboards, the method including making a core from a sheet shaped material, from which a part of a locking system for vertical locking of the floorboards is to be formed, impregnating and/or staining the core surface with a substance at least in portions which in the completed floorboard will constitute a joint edge of the completed floorboard, and arranging an surface layer on the core surface.
