Heat treatment is often used to improve dimensional stability of wood. This research was performed in order to determine how the heating process affects mechanical properties and decay resistance of oak and lime wood. Specimens were subjected to 3 hour heating at 130, 160, 190 and 220 ◦C temperatures. After undergoing heat treatment, mechanical properties of heated and unheated specimens were tested. The results showed that treated specimens had lower mechanical properties compared to untreated ones. Moreover, the mechanical strength decreased with an increase in the treatment temperature. On the other hand, the higher the heating temperature, the better wood resistance to decay.
