Wood is a renewable natural lignocellulosic material. However, its hygroexpansion characteristics dramatically shorten its service life, and limit its application. In this study, wood was treated in a silicone oil bath at different temperatures to improve its dimensional stability. Results demonstrated that the silicone oil treatment decreased the tangential swelling coefficient by 13% when treated at 80 °C and by 34% when treated at 160 °C and the radial swelling coefficient by 12% when treated at 80 °C and by 49% when treated at 160 °C. Also, the moisture absorption was reduced by the treatment.
