Abstract

A method of producing a modified wood product which includes the steps of sourcing a quantity of timber which has a moisture content in the range of 12% to 20%: subjecting the timber to a first stage in which the timber is heat treated; and subjecting the timber to a second stage in which the timber is impregnated with a protective wax-based composition which has a melting point in excess of 100°C.
