Abstract
Since ancient times, heating wood has been used a method to dry and modify its properties. Nowadays, heattreatment is used in industrial processes for the same reasons. Treatment at temperatures above 150 °C canchange the color, improve resistance to biodegradation and enhance dimensional stability. However, losses in themechanical and technological strength of wood may also occur, and this drawback is a limitation for the use ofheat-treated wood in a broad range of products. The treatment method used in the world is called “Thermowood”and this method can industrially applied in Finland. The method involves heating wood in a steam atmospherewhere the heat causes chemical changes in the structure of the wood. In this study, the effect of heat treatment onwood properties was investigated.
