A floor and wall covering plank includes sequentially, from bottom to top, a waterproof substrate, an adhesive layer, a veneer layer, a paint protective layer, a UV protective layer. The plank may further include optionally one or more of a padding layer and veneer layer below the waterproof substrate. The edges of the planks are routed to form a click locking system, squared or angled edges, or a tongue and groove configuration for assembling different planks together to form a floor or a wall covering. The waterproof substrate includes, in weight percentage, about 20-50% polymer material such as vinyl containing thermoplastics resin, about 20-50% calcium carbonate filler, and about 3-20% of the wood flour. A method is provided to make the floor and wall covering plank. The method includes extruding the waterproof core substrate.

A method and fastening device for attaching polyester fiber panels to a substrate, such as a wall or a ceiling. The fastening device comprises an anchor part for attachment to the substrate and a fastening part for attachment to the panel. The fastening part comprises a cylindrical portion, a helical member surrounding the cylindrical portion for penetrating the panel upon rotation of the helical member and a recess in the cylindrical portion for receiving the anchor part. The thread angle of the leading edge of the helical member is greater than the thread angle of the trailing edge.

A panel, in particular a floor panel, has a core of a wooden material, in particular MDF or HDF, or a wooden material/plastic mixture. A pattern is arranged on a visible side. The visible side is provided on at least one side edge (I, II) with a chamfer running at an angle α hereto and a length (L). The angle α of at least one of the chamfers varies over the length (L).

A backed panel comprising a facing panel and a backing panel. The backing panel has a groove, recessed portion, or any other suitable type of relief channel adapted to receive a side edge portion of a facing panel of an adjacent backed panel. By providing a space to receive a side edge portion of an adjacent facing panel, the relief channel may enable an improved lap joint to be established between adjacent backed panels.

A method for determining the moisture content of at least one resin layer provided on at least one wooden board as carrier board, wherein between the at least one resin layer and the carrier board an NIR reflecting layer is provided, including recording of at least one NIR spectrum of the at least one resin layer provided on the at least one carrier board using a NIR detector in a wavelength range between 500 nm an 2500 nm; determining the moisture content of the resin layer by comparing the NIR spectrum recorded for the resin layer to be measured with at least one NIR spectrum recorded for at least one reference sample with known moisture content by means of a multivariate data analysis, wherein the at least one NIR spectrum recorded was determined previously using the same NIR detector in a wavelength range between 500 nm and 2500 nm.

A mounting clip (1) for the floating mounting of wall and ceiling panels consisting of composite wood materials, said panels being connected to one another without adhesive by corresponding locking profiles to form a wall or ceiling covering and being fastened to a substructure. The mounting clip has a base board (2), a receiving portion (4) formed in one piece with the base board and intended for engaging in a locking profile of a panel, wherein the receiving portion has a distancing piece (5) arranged as far as possible perpendicularly to the plane of the base board, and a contacting piece (6), which adjoins the distancing piece and is arranged as far as possible parallel to the plane of the base board, and a slot (8) is provided in the base board for fastening the mounting clip to a fastening means on the substructure the slot can be at least 1.5-4 cm long and extend transversely with respect to the contacting piece.

The invention relates to an area covering element including at least one sheet-like carrier core, at least one protective layer and a decorative layer arranged between the sheet-like carrier core and the at least one protective layer. The sheet-like carrier core consists in this case of a strong, load-bearing carrier material and has at least an upper side and an underside arranged opposite from the upper side and also at least a first and second side face, arranged opposite from one another and respectively joining the upper side and underside. The decorative layer is formed by a printed film, which is firmly connected to the carrier core, the printed film at least partially covering at least the upper side and the first and second side faces of the sheet-like carrier core and the protective layer covering the full surface area at least of the printed film connected to the carrier core.

Structural insulated wall and roof sheathing systems for use in building construction designed to provide a structural building envelope that is moisture permeable but protects from bulk water, excess air, and thermal transfer.

A panel having a substrate and a top layer provided thereon, wherein the top layer comprises at least a melamine resin and a binder, the binder being selected from the group comprising: polyacrylates based binder, polyvinyl acetate based binder, polyester based binder, acrylic copolymers based binder or urethane based binder.
