Oriented strand board

OSB is easily identifiable by its characteristic wood strands.

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. It was invented by Armin Elmendorf in California in 1963.[1] 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.

Oriented strand board is sometimes confused with chipboard, a synonym for particle board, whose "chips" are of a size that a lay person would likely describe as "particles".
