A problem that has long been recognized in the millwork industry is the over absorption of treating solution by occasional pieces of wood. The cause of the problem has been well established, but there has been no widely accepted method for detecting highly permeable material in the production process. An air-pressure-based method was utilized to detect highly permeable wood. The method applied a regulated pressure to the surface of a board and the pressure between the regulator and the board was measured. The method is capable of rapidly measuring the surface permeability on the face of boards. The method was used on known highly permeable wood and wood with induced permeability. The method would enable millwork producers to effectively sort the highly permeable wood from normal wood.
