A system for introducing a noise-dampening polymer in-line in the manufacturing process of a manufactured wood product to achieve higher acoustic performance in siding, sheathing, roofing, flooring, and similar applications using the manufactured wood product. Several lines or bands of the noise-dampening polymer are deposited transversely across one side or face of the product. The polymer is deposited where the product is expected to contact joists or studs. The polymer may be a viscoelastic polymer.

Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

In a system for producing room elements, in particular walls, from individual construction elements, in particular made of wood, which are connected to one another to form the room element, at least four construction elements have different forms but are adapted to one another in terms of their dimensions. To this end, construction elements made of solid material are provided and construction elements consisting of hollow elements, into which an insertion frame is inserted. The construction elements are interconnected by means of pins, which are fastened in holes in the interior of the construction elements.

A wall element including upper and lower elements at upper and lower edges. A first side element extending along the first side, a second side element extending along the second side and a substantially rectangular board are present. The upper and lower elements include a first edge coinciding with the first side and a second edge coinciding with the second side, wherein the first and second edges are arranged in an angle with respect to a plane perpendicular to the outer surface, the angle lies within the interval 20°-45°, and the first and second side elements extending parallel to the plane, perpendicular to the board and having a total extension corresponding to the extension of the upper and the lower element in the plane, wherein the first side element bear against the plate and the second side element extend from the inside of the wall element.

A method for coating a building panel, including applying a first coating fluid including an organic binder on a surface of the building panel to obtain at least one coating layer, and applying barrier components and photocatalytic particles, preferably TiO.sub.2, on the at least one coating layer. Also, a building panel formed by the method.
