This is a non-veneered Building material composed of rectangular-shaped wood strands arranged in layers at right angles to one another, laid up into mats that form a panel and bonded with waterproof adhesives. Cross orientation makes the panels strong and stiff in both directions, and they contain no laps, gaps, or voids. Applications include subflooring, single-layer flooring, wall and roof sheathing, structural insulated panels, and webs for wood I-joists. It is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and resin adhesives (95% wood, 5% wax and resin). The layers are created by shredding the wood into strips, which are sifted and then oriented on a belt or wire cauls. The mat is made in a forming line, the layers are built up with the external layers aligned in the panel's strength axis with internal layers cross-oriented.
