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.

Two-piece tiles and/or floors comprised of a plurality of such two-piece tiles. In other embodiments, methods and/or processes for manufacturing or assembling such two-piece tiles, and/or to methods of assembling floors comprised of such tiles.

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.

A panel including a core, a top side, an 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 are lockable by a pivotal movement and positively lock 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 complementary receiving hook and an arresting hook. The arresting hook is assembled to the receiving hook by a joining movement in a plane perpendicular to the panel plane by the pivotal movement for the first edge pair. The receiving hook or the arresting hook has a holding groove for a separate locking element that provides vertical locking. A butting surface is arranged at the receiving hook substantially orthogonal to the top side. The arresting hook has a counterpart butting surface substantially orthogonal to the top side. The second edge pair has at least one sealing nose at a lower end of the counterpart butting surface of the arresting hook or at a lower end of the butting surface of the receiving hook. The sealing nose extends parallel to the respective panel edge over the entire length of the counterpart butting surface or the butting surface.

The present disclosure provides an artificial floor. The artificial floor comprises a plate body with a pad portion on a surface thereof. The pad portion contacts with a subfloor when the plate body is disposed on the subfloor. The plate body could be various kinds of the simulated floor such as linen, wood, or stone. The simulated floor is poor in wear resistance. The vibration or shaking during transportation may cause wearing between the simulated floors so as to damage the surfaces of the simulated floors. The subfloor may have an uneven surface, which may affect the surface flatness of the plate body disposed on the subfloor. Therefore, the pad portion of the plate body could be used as a cushion for the transportation process to protect the collision and wearing between the plate bodies. The pad portion could also be deformed locally to close the surface of the subfloor.

The invention relates to a flooring panel suitable for constructing a floor covering, which panel comprises a core layer and a decorative top layer and a layer situated between the core layer and the decorative top layer which enables improves sound performance.

Described is a set of panels (1,2), each panel comprising: ⋅ a top surface (5) and a bottom surface (4); ⋅ a first edge (6) and a second edge (7) parallel to the first edge (6), said edges (6, 7) extending between said top and bottom surfaces (5, 4); ⋅ a first groove (10) provided in the bottom surface (4) of each panel, said first groove (10) extending parallel to and along the first edge (6) of the panel; ⋅ a second groove (11) provided in the bottom surface (4) of each panel, said second groove (11) extending parallel to the first groove (10) along the second edge (7) of the panel; ⋅ a locking profile (3) allowing locking a first panel (1) with its first edge (6) to the second edge (7) of a second panel (2), said locking profile (3) comprising a base (16) and at least three protruding rims (17, 18, 19) extending parallel to one another in the longitudinal direction of the locking profile (3), a first rim (17) pressed in the first groove (10) of a first panel (1) and a second rim (18) situated in between the first and third rims (17, 19) of each locking profile (3) and cooperating with a part of the first panel (1) such that a section (13) of the bottom surface (4) of the first panel (1) is clamped between the first rim and the second rim (17, 18) of the locking profile (3), the third rim (19) configured to fit in the second groove (11) of a second panel (2) thereby locking the second panel (2) to the first panel (1), characterised in that at least the second rim (18) is continuous along the entire length of the locking profile (3). Further described is a method of manufacturing the set of panels.

The invention relates to an acoustic panel (1) for producing a wall and ceiling lining, comprising a front face (2) and a rear face (3) and recesses (4, 6) which extend from the front face (2) and from the rear face (3) into the acoustic panel. In order to provide an acoustic panel which both prevents the ability to see through from the front face to the absorber and also prevents particles from passing from the absorber through the acoustic panel (1), according to the invention at least one front-face recess and one rear-face recess (6) are arranged so as to be partially offset from one another and comprise a through-opening (7).

A set of planks (10) for covering a surface (12), comprising a first plank (16) having a first edge (24) defining a connecting tongue (26), and a second plank (18) having a second edge (28) defining a connecting groove (30), the first plank being movable between a disconnected position and a connected position, in which the connecting tongue is snap-fit in the connecting groove, the connecting tongue comprising a distal protrusion (40A) and a proximal protrusion (40B) adapted to abut upwards in the connected position against a proximal lip (42A) and a distal lip (42B) of the connecting groove. The second edge defines a guiding recess (38) at least partly located above the proximal lip (42A) for receiving the distal protrusion in an intermediate position of the first plank, in which the proximal protrusion abuts downwards against the distal lip.

The invention relates to a flooring panel suitable for constructing a floor covering, which panel comprises a core layer and a decorative top layer and a layer situated between the core layer and the decorative top layer which enables improves sound performance.
