A unique modified shiplap joint with a transverse spline extending into the respective edge of each piece of siding forming the joint. The spline ensures that the two adjacent pieces of siding are properly and adequately connected to each other, and, through the nail in the underlap portion of the joint, to the wall. The spline may be located in four possible positions: (1) attached to the back side of the underlap section of the joint (i.e., closest to the wall); (2) through the center of the underlap section of the joint; (3) directly attached to the front face of the underlap section of the joint; and (4) through the overlap section of the joint (i.e., closest to the outside face). The spline may be installed on one of the pieces of siding during manufacturing or at the factory, or alternatively, at the job site.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.

A unique modified shiplap joint with matching or corresponding reverse curves on opposing edges or ends of a piece of siding, each forming one-half of the joint: an underlap edge, and an overlap edge. The respective curves engage and resist or prevent separation of the edges, particularly under a pre-determined wind load. A fastener channel in the underlap section allows for a nail or fastener to be used, while the nail head is then covered by the adjacent overlap section. The respective edges form an angled gap, which is configured to prevent water or rain from entering.

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.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel.

[Object] To provide a building material, a stacked body of building materials, and a building-material construction method capable of improving the construction properties while suppressing a design surface from being damaged. [Solution] A building material includes a substantially rectangular plate-shaped building material body 2 that includes a first face 2F and a design surface 3 within the first face 2F; and a protective sheet S1 that is affixed to the building material body 2 in a peelable manner. The design surface 3 includes a covered region C1 that is covered with the protective sheet S1 and thereby protected and an exposed region B1 that is not covered with the protective sheet S1 and that extends along a first design end portion 3D, which is an end portion of the design surface 3.

A tile system for a burn room includes a plurality of interlocking surface tiles, each surface tile having an upper portion and a lower portion. The lower portion extends beyond at least a portion of a perimeter of the upper portion to define a flange. The system further includes a plurality of interlocking corner tiles configured to interact with at least one of the plurality of surface tiles; and a bracket system for securing the plurality of surface tiles and the plurality of corner tiles to a surface.

Floor covering, made of floor elements, which, at least at two opposite sides, comprise a male and a female coupling part, which allow that two of such floor elements can be interconnected at the respective sides at the respective sides by pushing one of these floor elements with the associated male coupling part, by means of a downward movement, home into the female coupling part of the other floor element, wherein at least one of said coupling parts, either the male coupling part or the female coupling part, is made as least partially in a filled synthetic material composite, such as extruded wood.

A floor panel is of synthetic material and forms a layer-shaped substrate with first and second pairs of opposite edges. The first pair of opposite edges has coupling parts forming a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, and forms a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels. The coupling parts on the first pair of opposite edges are realized substantially in the material of the floor panel itself. The floor panel is provided with an edge configuration on the second pair of edges allowing two of such floor panels to be positioned with their respective edge alongside each other and free from mechanical horizontally active locking systems.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel.
