Abstract: The invention concerns an extruded composite containing wood fibre material and polymer. The wood fibre material is wood material where the knot or branch content is at least 10 w-%, or bark, or would material into which extract material obtained by extracting knots, branches or bark has been absorbed. The amount of the polymer is 5-25 % from the weight of the composite. The composite has high hardness, and reduced moisture absorption and swelling properties. It can be used as constructional material.

Abstract: The invention relates to treatment of thermally modified wood. Thermal modification means controlled heating treatment of wood most appropriately under moist atmosphere so as to improve the dimensional stability and decay resistance of the wood. In accordance with the invention, the water absorption tendency of themally modified wood is reduced by treating the wood with a hydrophobic sizing agent reactive with cellulose, the treatment resulting in water-repellent wood. The wood can be treated with a solution containing a sizing agent, and then the solvent is evaporated by drying. Suitable sizing agents comprise alkyl ketene dimers (AKD) and alkenyl succinic acid anhydrides (ASA) dissolved in acetone, for instance. When ASA is used, the dried wood impregnated with the sizing agent requires an additional heating treatment in order to become hydrophobic.

Abstract: The invention relates to a method for treating thermally modified wood, to thermally modified wood treated according to the method and the use of resins as the protective agent for thermally modified wood. According to the invention, on the wood there is applied a liquid resin-based protective agent, which is dried and/or hardened, so that there is obtained a transparent protective surface for protecting the wood against the effects of weather. The protective agent can be phenol formaldehyde resin, melamine formaldehyde resin or urea formaldehyde resin, which is applied on the wood as an aqueous solution and dried by means of heat. Resin decreases the absorption of water in the wood and reduces the cracking of wood. Particularly phenol formaldehyde resin also prevents the wood from turning gray in the open air.
