Oriented strand board (OSB) is a type of engineered wood, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963. [ 1 ]
It is grooved on one side to receive the web. The web is typically made from plywood, laminated veneer lumber, or oriented strand board. After sizing the webs and flanges, they are assembled with water-resistant glue by pressing the web into the top and bottom flange. After assembly, the I-joist is end-trimmed and heat-cured or left at room ...
In dimensioned lumber construction, the rim joists are the same depth, thickness and material as the joists themselves; in engineered wood construction, the rim joists may be oriented strand board (OSB), plywood or an engineered wood material varying in thickness from 1 inch (25 mm) to as much as 1 + 3 ⁄ 4 inches (44 mm), though they are ...
Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces.. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite

[1] [2] It is similar to plywood but with distinctively thicker laminations (or lamellae). The grain of each layer of boards is usually rotated 90 degrees from that of adjacent layers and glued on the wide faces of each board, usually in a symmetric way so that the outer layers have the same orientation. An odd number of layers is most common ...

OSSB can replace wood oriented strand board (OSB) and particle board in structural and non-structural applications, such as interior and exterior walls for house construction, furniture and interior decoration.
