Oriented strand board (OSB) was introduced during the 1980s.
oriented strand board is made by people.
Used instead of plywood. Oriented Strand Board
OSB stands for oriented strand board. It is made of wood strands and waterproof adhesives. The strength of OSB board is equal to that of plywood.
The smooth side of oriented strand board (OSB) faces outward to provide a clean finish for surfaces like walls or roofs. The rougher side, with visible wood strands, is typically installed facing inward for structural support.

The material that subfloor is typically made of is plywood or oriented strand board (OSB).
Oriented Strand Board (OSB) is not waterproof, but it can withstand some moisture if properly sealed or treated.

A 1/2" sheet of oriented strand board weighs about 52-53 pounds and a 3/4" sheet weighs about 78-80 pounds. It appears that it is not possible to be more precise because the density of the material is not standardized and can vary depending on the moisture content.
The density will vary depending on the moisture content and the type of wood used in the board but a typical board has a density of 630 kilograms per cubic metre. To work out the surface density (kilograms per square metre) of a board, multiply 630 by the thickness (in metres) of the board.
The best practices for applying an OSB sealer to protect and enhance the durability of oriented strand board surfaces include thoroughly cleaning the surface, applying the sealer evenly with a brush or roller, allowing sufficient drying time between coats, and following the manufacturer's instructions for proper application and maintenance.
A sheet of 12mm OSB (oriented strand board) typically weighs around 52-56 pounds. However, the weight can vary depending on the specific dimensions and density of the board.
