The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada [1]. It equals the volume of a board that is one foot (30.5 cm) in length, one foot in width, and one inch (2.54 cm) in thickness, or exactly 2.359 737 216 liters .
In 1971 "Micro=Lam LVL" was introduced. "Micro=Lam LVL" consisted of laminated veneer lumber billets 4 feet (1.2 m) wide, 3 + 1 ⁄ 2 inches (89 mm) thick, and 80 feet (24 m) long. Troutner proved the structural capabilities of his Micro=Lam product by building a house in Hagerman, Idaho, using beams made of Micro=Lam.
For example, a "2×4" board historically started out as a green, rough board actually 2 by 4 inches (51 mm × 102 mm). After drying and planing, it would be smaller by a nonstandard amount. Today, a "2×4" board starts out as something smaller than 2 inches by 4 inches and not specified by standards, and after drying and planing is minimally 1 ...
The wood is categorized as a board if its width is less than 2 + 1 ⁄ 2 in (64 mm), and its thickness is less than 1 + 1 ⁄ 2 in (38 mm). A plank used in a building as a horizontal supporting member that runs between foundations, walls, or beams to support a ceiling or floor is called a joist .
There is disagreement amongst scholars about which variety was the strongest, however the North American white pine was considered more resilient, one fourth lighter in weight, and exponentially larger; reaching a height of 250 feet, several feet in diameter at the base, and weighing in as much as 15 to 20 tons.

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 ]
39 in (990 mm) wainscoting using 3 in (76 mm) tongue and groove pine boards. Panelling (or paneling in the United States) is a millwork wall covering constructed from rigid or semi-rigid components. [1] These are traditionally interlocking wood, but could be plastic or other materials.
Australian standard pallets are defined by Australian Standard AS:4068-1993 Flat pallets for materials handling. [2] They can be manufactured in hardwood or softwood, where hardwood is good for durability, weather tolerance and very heavy loads of over 2 tonne. 1165 × 1165 mm softwood pallets can also be manufactured using lighter timber suitable for use as a lightweight pallet using 19mm ...
