Abstract
The invention is directed to a tongue and groove product which comprises a first and second major surface and a first and second longitudinal edge. The first longitudinally edge includes a longitudinally-extending groove. The second longitudinal edge includes a longitudinally-extending protruding tongue for interlockingly engaging a complimentary grooved longitudinal edge of an adjacent tongue and groove board. The protruding tongue has an upper and a lower longitudinally-extending surface. The major design feature of this invention is that the protruding tongue has at least one substantially vertically-extending opening formed therein. Each of the openings extends through the protruding tongue from said longitudinally-extending upper surface to said longitudinally-extending lower surface for providing at least one drain path for water to drain by gravity from said first major surface downwardly through each said vertically-extending opening. This prevents an accumulation of water on the tongue and groove board. In the preferred case, the opening in the protruding tongue comprises a substantial vertically-extending notch.
