The present invention is concerned with a method for obtaining a wood panel, preferably an OSB panel, with significantly reduced thickness swelling properties when exposed to or contacted with moisture or water. The novel dimensionally stable panels are obtained by an alternate vacuum&mdash;steam injection method. The method is an after-fabrication, or post-treatment method, and involves one or more cycles of applying a vacuum followed by injection of hot steam in a sealed treatment chamber.
