Strong and dimensionally stable wood panel assembly and method of fabrication thereof

A method for fabricating a wood panel assembly comprising the acts of providing a steam-treated wood panel assembly comprising two faces and a core submitting the steam-treated wood panel assembly to an elevated pressure under an elevated temperature so as to decrease its thickness is described herein. Also described herein is a wood panel assembly having a high strength and a high resistance to swelling under moisture. The assembly comprises two faces, each of the faces having an outer surface; and a core provided between the two faces. The wood panel assembly, after a steam-treatment, is submitted to a high pressure under an elevated temperature to yield the high strength and high resistance to swelling under moisture properties.
