Abstract: A wall or ceiling panel includes a substrate layer and a top layer. The substrate layer, on at least one pair of opposite edges, is provided with mechanical coupling parts, and a backing layer is provided onto the surface of the substrate layer opposing the top layer, which backing layer at least partly covers the substrate layer. The backing layer at least partly extends beyond one of the edges. An assembly of a wall or ceiling panel, and a A connection member for an assembly of a wall or ceiling panel is configured to connect to the mechanical coupling parts on at least one of the edges of the substrate layer, and to at least partly extend beyond one of the edges of the substrate layer.

Abstract: A finishing profile for a floor covering includes a finishing strip. The finishing strip includes a substrate, and the finishing strip has a top layer on the upper side of the substrate. The top layer has a decorative layer. The finishing profile further has a rail. The main region of the rail is connected to an attachment region of the finishing strip. The attachment region extends vertically on the underside of the substrate. The finishing strip defines a first curved portion. The substrate and the top layer are uniformly curved.
