Abstract

A composite wood panel having a first and second longitudinal edge, wherein the first edge includes a groove and the second edge includes a tongue for interlocking and engaging the complementary edges of an adjacent tongue and groove wood panel. The groove has two sides and a base transverse thereto, and the tongue has two side walls and a head extending outward from the second longitudinal edge, thereby forming a juncture between the side walls of the tongue and the second longitudinal edge. A shoulder is located at the juncture between one side wall of the tongue and the second longitudinal edge. Upon assembly of two complementary wood panels as described above, a novel tongue and groove joint is formed wherein the shoulder will abut the first longitudinal edge, thus preventing the tongue from being completely introduced into the complementary groove. As a result, a first aperture is formed between the head of the tongue and the base of the groove and a second aperture is formed between the first and second longitudinal edge both above and below the engaged tongue and groove.
