A set of essentially identical floorboards each including a front face and a rear face extending in the horizontal plane, a core, and a surface layer, a mechanical locking system is arranged at least at two opposite edges for connecting a floorboard with an adjacent floorboard in a horizontal and a vertical direction, said mechanical locking system being configured for connecting the floorboard with the adjacent floorboard by vertical folding, wherein one of said opposite edges is provided with a horizontally extending protrusion at an upper edge, and wherein said protrusion is configured to overlap a surface groove at an upper edge of the other of said opposite edges, such that two connected and adjacent floorboards have upper overlapping edges.

A spacer assembly for flooring systems, such as for aircraft flooring, includes a spacer panel and one or more flooring panels. The spacer panel includes a core layer and a bottom layer. The core layer has a top face and a bottom face and the bottom layer has a lower face and an upper face that is bonded to the bottom face of the core layer. The lower face of the bottom layer is located adjacent to a structural floor and the bottom layer slides over the structural floor. The one or more flooring panels connect to the top face of the core layer, where the flooring panel and the spacer panel slide over the structural floor. Two or more flooring panels can be connected, such as by an adhesive material, to a spacer panel with a sealant member between the flooring panels to avoid infiltrations of liquids.

A magnetic perimeter attachment for an interior space of a vehicle, such as an aircraft or other such vehicle. The vehicle flooring section includes a magnetic tape attached to the structural floor of a vehicle and a spacer panel magnetically coupled to the magnetic tape, where the spacer panel is located on the perimeter of the vehicle flooring section. The magnetic tape includes a carrier layer having an acrylic or rubber adhesive material, which is for bonding to a structural floor panel of the vehicle. The tape also includes a magnetic material deposited in the carrier layer. The magnetic material and the adhesive material are located on opposite sides of the carrier layer.

A gap bridging device including two anchoring devices that anchor the gap bridging device at two building elements that are separated from each other by a gap; and a bridging device that is connected with one of the two anchoring devices respectively at longitudinal sides of the bridging device that are arranged opposite to each other, so that position changes of the building elements relative to each other are compensated by a shape-change of the bridging device, wherein the two anchoring devices respectively include a base element that is anchorable at one of the two building elements and a top element that is connected with the base element by a plurality of bolts in a force transferring manner and connected with the gap bridging device.

Surface coverings, such as floor coverings, with an interlocking design are described. Methods of making the surface coverings are further described. A plank including a resilient composite sheet having four sides, an upper surface, a lower surface, and an overall thickness, and said composite sheet comprising at least one base layer, wherein said at least one base layer comprising at least one polymeric material and at least one filler, wherein opposite sides of the composite sheet comprise a first tongue on a first side and a first groove on the opposite second side, wherein the first tongue and first groove have complementary shape to each other to be interlockingly engageable with a corresponding groove or tongue on an adjacent floor plank.

Ceramic and stone tiles are shown, which are provided with a locking system including a separate strip part connected to vertical and horizontal grooves formed in the tile edge. A set of ceramic or stone tiles including a first tile provided with a first edge and a second tile provided with a second edge wherein the tiles are provided with a locking system for locking the first edge to the second edge in a horizontal direction parallel with a tile surface and in a vertical direction perpendicular to the horizontal direction, said locking system includes a first and a second tongue and a strip part provided with a first and a second locking element.

Ceramic and stone tiles are shown, which are provided with a locking system including a separate strip part connected to vertical and horizontal grooves formed in the tile edge. A set of ceramic or stone tiles including a first tile provided with a first edge and a second tile provided with a second edge wherein the tiles are provided with a locking system for locking the first edge to the second edge in a horizontal direction parallel with a tile surface and in a vertical direction perpendicular to the horizontal direction, said locking system includes a first and a second tongue and a strip part provided with a first and a second locking element.

Wood flooring is described, which provides resistance to surface liquids by reducing or eliminating checking on the surface of the wood and transmission liquid through the seams in an installed wood floor. This is achieved by combining a surface coating, a wood veneer and core or solid wood, a tongue and groove profile, and application of a sealer along the tongue and groove or locking profile.

A set of essentially identical subfloor panels including a joint configured to be glued, wherein the joint includes an element at a strip which protrudes from a first joint edge at an edge of a panel and an element groove at an adjacent edge. The joint includes a flexible tongue which is configured to cooperate, in the joined position, with a tongue groove for positioning of the panel relative the adjacent panel in a first vertical direction. The joint is configured for a joining of the edge and the adjacent edge by a vertical motion of the edge relative the adjacent edge. A space above the strip and between the element and the first joint edge is configured to be filled partly or completely with a glue before the edge and the adjacent edge are joined.

A method and kit for renovating and reconstructing wet rooms, wherein panel modules are attached to a wall, floor, and/or ceiling of the wet room, by providing panel modules having a water-impermeable coating or core; determining an installation position of a panel module; attaching a water-resistant sealing strip section to form an outer contour of the panel module; applying a water resistant sealing adhesive to the sealing strip section such that the sealing adhesive continuously underlays edge regions of two adjacent panel modules; and pressing a first panel module onto a first subregion of the sealing adhesive and a second panel module adjoining the first panel module whereby the two adjacent side regions of the panel modules are completely underlaid with sealing adhesive to produce a seal point between the panel modules to prevent moisture from entering the wall, floor, or ceiling through a joint formed between the panel modules.
