Oriented strand board, or OSB, is a type of lumber that shares many properties with plywood or fiberboard.While other types of wood sheeting typically feature a smooth surface, this type features a rough surface made up of hundreds of wood chips.While these scraps of wood may appear randomly placed, each piece of wood is actually aligned to maximize the strength of the panel. Oriented strand board (OSB) is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. [citation needed], The adhesive resins types used include: urea-formaldehyde (OSB type 1, nonstructural, nonwaterproof); isocyanate-based glue (or PMDI poly-methylene diphenyl diisocyanate based) in inner regions with melamine-urea-formaldehyde or phenol formaldehyde resin glues at surface (OSB type 2, structural, water resistant on face); phenol formaldehyde resin throughout (OSB types 3 and 4, structural, for use in damp and outside environments).[4]. We form the layers by shredding wood and then joining them together with adhesive. 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[citation needed]). Oriented strand board (OSB) is an engineered wood-based panel. Oriented Strand Board (OSB) is a man-made product created from wood bits, which are pressed and bound together by adhesive resin and glue. This mat is then cured, trimmed to size The mat is formed in a forming line. Phenol-formaldehyde products are considered to be relatively hazard-free. It was invented by Armin Elmendorf in California in 1963. However, pieces of furniture built using OSB do not require any staining or painting because the design of the board itself can stand alone. OSB is also used in furniture production. While OSB does not have a continuous grain like a natural wood, it does have an axis along which its strength is greatest. Wood strips on the external layers are aligned to the panel's strength axis, while internal layers are perpendicular. The finished sheet size varies by country. Relative to their strength, OSB panels are light in weight and easy to handle and install. The leading resource for information about engineered wood products.
