The present invention relates to a method of heat treatment of a solid piece of wood, such as sawn timber. According to the method, the temperature difference between the inside temperature of the heating oven and, correspondingly, the inside temperature of the wood is maintained at a maximum of 10° C., after the level of moisture content of the piece of wood has reached the fibre saturation point of the wood. A small temperature difference such as this is maintained when the temperature is further increased until a level of moisture content is reached at which the strength properties of the piece of wood are at their best. By means of the solution it is possible to considerably reduce the formation of internal cracks in heat treated wood. |
