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 ]
Producing split straw of sufficient length was the key technical innovation making OSSBs possible. OSSB is thus sometimes referred to as oriented split straw board. [4] Formaldehyde free resin is added to the straw and the fibres are oriented for strength and appearance, and shaped into a mat through directional mat forming.
In the United States, SIPs tend to come in sizes from 4 to 24 feet (1.2–7.3 m) in width. Elsewhere, typical product dimensions are 300, 600, or 1,200 mm wide and 2.4, 2.7, and 3 m long, with roof SIPs up to 6 m long.
Norbord Inc. was a Canadian company that manufactured wood-based panels and became the world's largest producer of oriented strand board (OSB). Norbord also manufactured particleboard, medium-density fibreboard (MDF) and related value-added products.
Waferboard belongs to the subset of reconstituted wood panel products called flakeboards. [1] It is a structural material made from rectangular wood flakes of controlled length and thickness bonded together with waterproof phenolic resin under extreme heat and pressure.

While plywood became widespread by the early 20th century, the invention of LVL was not until the 1980s after the invention of oriented strand board. [3] The American Wood Council's National Design Specification for Wood Construction is generally updated on a 3- to 5-year cycle. The 1991 release is the first release which mentions LVL.
Parallel-strand lumber (PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses. It is used for beams, headers, columns, and posts, among other uses.
