Wood is pressure treated in a pressure autoclave by drawing an initial vacuum in the autoclave to remove air from the autoclave and the wood; filling the autoclave with inert gas while the autoclave is under vacuum; filling the chamber with a preservative comprised of a silane compound, a liquid hydrocarbon solvent, and optional pesticides; pressurizing the autoclave to impregnate the wood with the preservative; draining the preservative from the autoclave; and applying a final vacuum to the autoclave to remove excess solvent from the autoclave and the wood.
