A rectangular panel which, on the first and on the second pair of opposite edges, has coupling parts configured for easy installation in a wall or ceiling covering. A locking occurs between the coupled panels; and a wall or ceiling covering that includes such panels.

A composite wood prefabricated wall panel configured for reduced moisture absorption includes a composite wood panel body, one or more connection components, and a priming layer. The composite wood panel body includes a front face, a rear face, and at least one edge. The one or more connection components are affixed to the rear face or the at least one edge, and the one or more connection components are configured to secure the composite wood prefabricated wall panel to one or more structural members of a prefabricated wall system. The priming layer is disposed over one or more surfaces of the composite wood panel body.

A profile element for attachment to the rear side of a faade panel, which in turn is fastened to a base such as a building surface or substructure. The profile element is formed in one piece and includes three functional sections arranged one after another: a fixing section for fixing the profile element to a base; a support section for attachment to the faade panel; and a spacer element which, in the installed state, ensures the correct distance between the base and the rear side of the faade panel. The profile element is extendible by a supplementary element, which has functionally similar elements and is only used if required by the geometry of the faade panel. The supplementary element is usable for positive connection to the profile element of an adjacent faade panel. Such a faade system provides flexibility for a wide variety of types and dimensions of faade panels.

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.

A system includes one or more decorative screen panels configured at an initial position. The system also includes a locking and spacing apparatus positioned on an exterior portion of the one or more decorative screen panels. The spacer is positioned to receive a locking mechanism. The locking mechanism is positioned on the locking and spacing apparatus over the one or more decorative screen panels. A first portion of the locking mechanism is positioned within the spacer. A second portion of the locking mechanism is positioned under the locking and spacing apparatus and configured to move in a perpendicular direction. The movement in the perpendicular direction secures the locking mechanism within the locking and spacing apparatus.
