A method of producing a veneered element, including providing a substrate, applying a sub-layer on a surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure to the veneer layer and/or the substrate, such that at least a portion of the sub-layer permeates through the veneer layer. Also, such a veneered element.

A formaldehyde free adhesive composition and a plywood obtained by the adhesive composition is provided, and the plywood retains desired performances, such as water resistance and workability.

A composite wall panel having a front surface, a rear surface, and side surfaces extending therebetween is provided. The panel includes a cured composition of pieces of cellulose and/or chaff and at least one binder. A wall assembly is also provided. The assembly includes: a frame including a plurality of linearly arranged elongated studs having a top end, a bottom end, and a first longitudinal side and a second longitudinal side extending between the respective ends; a plurality of interconnected wall panels mounted to the first side of the elongated studs of the frame to form a first wall portion; a plurality of interconnected panels mounted to the second side of the elongated studs to form a second wall portion; and an insulating layer inserted within a cavity between the first wall portion and the second wall portion.

A method of producing a moulded article comprising a thermoset polymer and particles of porous natural materials, such as wood materials, and uses thereof. The composite material has a continuous matrix of a hardened thermoset polymer and, distributed within the matrix, and the particles are at least partially encased by the thermoset polymer. The method comprises the steps of providing a mould with two opposite pressing surfaces, said pressing surfaces defining a space between them; feeding particles of porous natural materials into the space between the pressing surfaces; advancing the surfaces towards each other to compress the particles in said space; feeding unhardened thermoset resin in liquid form into the mould so as to fill at least said space between pressing surfaces while keeping the particles compressed between the pressing surfaces; and curing the thermoset resin in the mould to provide a moulded composite article.

A web structural body includes cellulose fibers and a binding material binding the cellulose fibers, and in the web structural body described above, a molten rate of the binding material at a surface of the web structural body is higher than a molten rate of the binding material at a center in a thickness direction of the web structural body.

A method for producing a board according to the present invention includes the steps of: (A) dispersing a polycarboxylic acid, a saccharide, and ammonium sulfate in a collection of small wood pieces; and (B) subjecting the collection of small wood pieces containing the dispersed polycarboxylic acid, saccharide, and ammonium sulfate to hot press molding to form a board comprising the small wood pieces bonded together.
