Oriented strand board is a specific type of engineered wood. This is a type of building material made by breaking down raw or scrap wood, and then turning it into panels and various other shapes. Oriented strand board is very similar to both particleboard and plywood.
OSB is made by breaking down wood into small chips and then orienting them in a specific way, mixing them with a lot of adhesive and resin, and then pressing them into specific shapes. The chips are organized into a multitude of layers, with the number of layers depending on the intended thickness of the final product.
Four types of OSB
OSB-1- is intended for use in conditions of low humidity (furniture, paneling, and packaging).
OSB-2- used in the manufacture of load-bearing structures in dry conditions.
OSB-3- is used in the manufacture of load-bearing structures in wet conditions.
OSB-4- heavy-duty load-bearing boards for use in humid conditions
Advantages of Oriented Strand Board
OSB is extremely strong. Much stronger than plywood. In fact, OSB has about twice the shear strength of plywood.
OSB is going to be extremely water-resistant and, in some cases, even totally waterproof.
OSB Can Be Massive. The panels can reach up to 24 feet in length, thus covering a whole lot of area at once.
OSB is Affordable
OSB is Somewhat Eco-Friendly
