A wood substrate or member is included, having an increased density with respect to natural, untreated wood. The process includes drying the wood prior to application of heat and pressure, which are controlled to reduce or eliminate color change on a surface of the wood member where heat and pressure are applied.

A process for the production of OSB wood-based panels including: a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and, optionally, gluing the non-steam treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board. The steam treatment takes place after the wood strands have been produced and made available, or after the wood strands have been sifted and separated according to the use of the wood strands for the middle and top layers of the panel. Also, an OSB wood-based panel made using the process.

The invention relates to a wood conditioning system comprising: a first chamber; a second chamber; at least one air conveyor device for circulating air between the first chamber and the second chamber; the second chamber comprising at least one device for spraying water substantially against a direction of the circulated air. Some aspects of the invention relate to a method for wood conditioning.

Disclosed is a process for the treatment of wood strands suitable for the manufacture of OSB boards, in which the wood strands are treated with steam without drying after extraction, the steam being passed over the wood strands at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar. Also disclosed is a process for the production of OSB wood-based boards including the steps of a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and gluing the non-steam-treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board.

A method of and system for producing Class-A fire-protected oriented strand board (OSB) sheets. Each Class-A fire-protected OSB sheet has: a core medium layer made of wood pump, binder and/or adhesive materials; a pair of OSB layers bonded to the core medium layer; a clean fire inhibiting chemical (CFIC) coating on the surface of each OSB layer, made from CFIC liquid applied to the surface by dipping the OSB sheet into the CFIC liquid in a dipping tank, allowing shallow surface absorption into the OSB layers and ends of the core medium layer at atmospheric pressure; and a moisture, fire and UV protection coating spray coated over the CFIC coating to provide protection against moisture, fire and UV radiation from Sunlight, which is quickly dried by passing through a drying tunnel on the production line.
