Industry trade groups assert that formaldehyde emissions from North American OSB are "negligible or nonexistent".. Look for manufacturers that work with forests that are managed responsibly (such as FSC- or SFI-certified land) and gather raw materials from a close radius (say, 50 to 150 miles). Manufactured from waterproof heat-cured adhesives and rectangularly shaped wood strands that are arranged in cross-oriented layers, OSB is an engineered wood panel that shares many of the strength and performance characteristics of â¦ A viable alternative to plywood, this OSB Board is engineered to prevent any cupping, warping or splitting. OSB (Oriented Strand Board) Sub-Flooring. OSB Basics OSB is now used for about 70 percent of all floor, wall and roof sheathing in North America. Performance Category. With a small expansion coefficient, no distortion, good stability, uniform material and nail holding high performance. For exterior wall applications, panels are available with a radiant-barrier layer laminated to one side; this eases installation and increases energy performance of the building envelope. OSB boards (oriented strand board or oriented structural board) are wood-based panels made of long, thin chips, the so-called strands. Describes OSB composition, properties, code acceptances, and applications. Oriented Strand Board (OSB) Oriented Strand Board. The mat is placed in a thermal press to compress the flakes and bond them by heat activation and curing of the resin that has been coated on the flakes. It has multiple uses, and the material is very flexible! High vs. low solids content This flexibility allows for numerous formulation choices that will help take your products to the next levelâand our technical service represâ¦ Individual layers can also vary in thickness to give different finished panel thicknesses (typically, a 15 cm (5.9 in) layer will produce a 15 mm (0.59 in) panel thickness). MDF is made of wood powder .  When tested to failure, OSB has a greater load-bearing capacity than milled wood panels. This can be seen by observing the alignment of the surface wood chips. OSB (Oriented Strand Board) is an engineered wood panel made of wood strands, which are in cross-oriented pattern and bonded with adhesives under heat and pressure .  OSB may have a rough and variegated surface with the individual strips of around 2.5 cm × 15 cm (1.0 by 5.9 inches), lying unevenly across each other, and is produced in a variety of types and thicknesses. Phenol-formaldehyde products are considered to be relatively hazard-free. Although oriented stranded board (OSB) has similar uses to plywood, it has a much coarser finish.
