OSB panels that bear the APA trademark are manufactured under APA's rigorous quality assurance program, and are recognized by the U.S. OSB is designed to withstand exposure to the weather during construction. This is especially useful when the panels are used for roof sheathing, because the textured surface provides better footing for workers. Frequently, the panels are textured or splatter-coated on one side to increase traction on the panel surface. Relative to their strength, OSB panels are light in weight and easy to handle and install.

The panels remain flat and square during storage and transportation, so they arrive at the jobsite flat and easy to install tongue-and-groove effortlessly fit together. Performance begins when the panel leaves the manufacturer. Nearly four decades of laboratory tests and use in the field have proven that OSB is an excellent performer. panels can be manufactured in many sizes simply by altering the cutting pattern. The mats are trimmed to a workable size and then moved to a press where the wood strands and adhesive are bonded together under heat and pressure to create a structural panel. Face layer strands generally run along the panel, while core layer strands are randomly oriented or run across the panel. Liquid or powder adhesive is applied to the dried strands and then transported in layers on a conveyor system to a forming line, where the layers are cross-oriented into mats. The strands are dried with heat in a large rotating drum which is screened to grade for strands that are the correct size. In the first phase of OSB manufacture, logs are debarked and cut to a uniform length. Plus, about 85-90 percent of a log can be used to make high quality structural panels, and the remainder-bark, saw trim, and saw dust - can be converted in to energy, pulp chips or bark dust. OSB uses the wood resource very efficiently, in part because sheathing panels can be made using smaller, younger fast-growing smaller, younger fast-growing tree species, such as aspen and southern yellow pine. As an added feature, panels are often textured on at least one side to provide a slip-resistant surface. Most panels are also treated with a sealant on the panel edges to guard against moisture penetration during shipment. OSB is bonded with water-resistant adhesives.

OSB is composed of thin rectangular-shaped wood strands arranged in layers at right angles to one another, which are laid up into mats that form a panel. OSB is manufactured in a cross-oriented pattern similar to plywood to create a strong, stiff structural panel. PRODUCT FEATURES OSB is made from real wood The APA trademark also assures you that an OSB manufacturer is committed to quality.

The APA trademarks is the manufacturer's assurance to you that the OSB panel is produced to APA's stringent requirements as well as to U.S. APA began providing a quality assurance program for OSB in 1981 and has led the engineered wood industry in OSB research and quality program ever since. This product Guide from APA describes OSB's features, uses, quality assurance, and performance. Its high performance capabilities make OSB ideal for diverse markets, including material-handling applications, the structural insulated panel industry, do-it-yourself projects, wood I-joist products, and industrial applications such as furniture and trailer liners. OSB is a proven performer for many residential and nonresidential applications. OSB is engineered for strength and designed for a variety of applications.
