Abstract: The panelized roof sheathing construction system includes a plurality of panels attached to a building frame structure in substantially abutting relationship. Each panel includes a water resistant barrier layer secured atop the outward facing surface of the panel. The water resistant barrier layer includes a skid resistant surface. Joints between panels are sealed by strips of water resistant tape or the like. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners.

Abstract: Structural members, building structures, and methods for making them, are provided that are less prone to develop squeaks. The methods include, in one aspect, placing at least one panel on the flange surfaces of joists with an activatable adhesive provided between the panel and the flange surfaces to bond the flange surfaces to the panels in an effective long lasting manner. In another aspect, adhesive is introduced into a groove array in a joist flange surface to attach a panel pre-positioned on the grooved flange surface. Building frame structures, such as subflooring assemblies, made by the methods are also provided.

Abstract: The invention comprises a wall sheathing barrier system having moisture permeability and simple improved installation method. The system comprises adjoined structural panels. Each panel has an overlay paper bonded permanently to the structural panel, which provides a moisture permeable barrier and a textured skid-resistant surface. The skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. Further, the seams of adjoining panels are sealed with a sealing means to complete the moisture barrier.

Abstract: A wood composite board comprising balsam fir strands is disclosed.

Abstract: Disclosed is a wood panel comprising bamboo strands cut from the inner portion of the bamboo culm.

Abstract: A multi-layered composite wood panel including a core layer, a first surface layer and a second surface layer. The core layer is formed from wood flakes and has a top surface and a bottom surface. The first surface layer is adhered to the top surface of the core layer and includes strands of woven bamboo. The second surface layer is adhered to the bottom surface of the core layer and includes strands of woven bamboo. The core layer, first surface layer and second surface layer are bound together to form a substantially rectangular plane having a thickness of between about 0.25 inches and about 2.0 inches.

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, ?, with the upper surface, while a matching surface extends from the groove forming a generally acute angle, ?, with the upper surface, and the sum of ? and ? 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.
