Tongue and groove panel

Abstract

A composite wood panel is disclosed, the wood panel having parallel first and second longitudinal edges, and parallel upper and lower faces, and comprising: a groove formed along the second longitudinal edge, a complementary shaped tongue formed along the first longitudinal edge, and a barrier layer. A first surface extends from the tongue to the upper surface and forms a generally obtuse angle, α, with the upper surface, while a matching surface extends from the groove forming a generally acute angle, β, with the upper surface, and the sum of α and β is from about 175° to less than about 180°. The composite wood panel allows for convenient and fast assembly, particularly in constructing roofs, and also provides resistance against the penetration of water through the structure formed by the panels.

1 . A building construction panel, comprising:
 outer and inner faces each defining upper and lower edges, wherein the upper edges are longitudinally offset from each other and the lower edges are longitudinally offset from each other; and   upper and lower lateral sides, wherein the upper side extends between the upper edges of the outer and inner faces and the lower side extends between the lower edges of the outer and inner faces,   wherein the upper side includes a tongue and the lower lateral side includes a groove, wherein the upper side includes an upper transition surface extending at a non-perpendicular angle from the upper edge of the outer face to the tongue, and wherein the lower side includes a lower transition surface extending at a non-perpendicular angle from the lower edge of the outer face to the groove, so that when assembled with an adjacent lower-positioned panel, the lower transition surface of the lower side overlaps the upper transition surface of the upper side of the adjacent lower-positioned panel and the groove receives the tongue of the adjacent lower-positioned panel.   
     
     
         2 . The building construction panel of  claim 1 , wherein when assembled with the adjacent lower-positioned panel, the upper edge of the outer face is longitudinally lower than the upper edge of the inner face, and the lower edge of the outer face is longitudinally lower than the lower edge of the inner face. 
     
     
         3 . The building construction panel of  claim 1 , further comprising a barrier layer secured to an external surface of the outer face and wherein the barrier layer includes fibers impregnated with a sizing compound. 
     
     
         4 . The building construction panel according to  claim 3 , wherein the fibers are selected from the group consisting of cellulosic fibers, fiberglass fibers, polymer fibers, and glass fibers. 
     
     
         5 . The building construction panel according to  claim 3 , wherein the sizing compound is selected from the group consisting of asphalt and non-asphaltic sizing. 
     
     
         6 . The building construction panel according to  claim 3 , wherein the barrier layer is selected from the group consisting of asphalt-impregnated felt and high density overlay. 
     
     
         7 . The building construction panel according to  claim 1 , wherein the panel further comprises a radiant barrier material attached to the inner face. 
     
     
         8 . The building construction panel according to  claim 7 , wherein the radiant barrier material comprises dual layers. 
     
     
         9 . The building construction panel according to  claim 7 , wherein the dual layers include a layer of metal foil and a backing layer. 
     
     
         10 . The building construction panel according to the  claim 1 , wherein the tongue has beveled edges. 
     
     
         11 . The building construction panel of  claim 1 , wherein the tongue extends the entire length of the upper lateral side. 
     
     
         12 . The building construction panel according to  claim 1 , wherein the building construction is an oriented strand board. 
     
     
         13 . A roof construction for a building, comprising:
 a frame structure; and   a plurality of building panels attached to the frame structure, wherein each building panel includes
 outer and inner faces each defining upper and lower edges, wherein the upper edges are longitudinally offset from each other and the lower edges are longitudinally offset from each other, and 
 upper and lower lateral sides, wherein the upper side extends between the upper edges of the outer and inner faces and the lower side extends between the lower edges of the outer and inner faces, 
 wherein the upper side includes a tongue and the lower lateral side includes a groove, wherein the upper side includes an upper transition surface extending at a non-perpendicular angle from the upper edge of the outer face to the tongue, and wherein the lower side includes a lower transition surface extending at a non-perpendicular angle from the lower edge of the outer face to the groove, so that when two of the plurality of building panels are assembled, the lower transition surface of the lower side of the first panel overlaps the upper transition surface of the upper side of an adjacent lower-positioned panel and the groove receives the tongue of the adjacent lower-positioned panel. 
   
     
     
         14 . The roof construction of  claim 13 , wherein a gap is defined between the upper faces of adjacent panels when two panels are joined together. 
     
     
         15 . The roof construction of  claim 13 , wherein each panel further comprises a barrier layer secured to the upper surface thereof. 
     
     
         16 . The roof construction of  claim 15 , wherein each panel further comprises a radiant barrier layer secured to the lower surface thereof.
