You have probably seen OSB boards before when visiting your local home center or any construction site. Any home center will have OSB boards in different widths, thicknesses with some designed to be water-resistant and some just made to be dirt cheap.
OSB is an engineered man-made wood product with many of the same qualities as plywood and you can use oriented strand board in most of the same cases where you would use plywood. OSB is cut into large boards, which makes OSB a good choice if you have to cover larger areas with wood for a cheap price.
Many people choose to use OSB instead of plywood because OSB is cheaper.
OSB is usually cheap. Many times half the price of plywood. The reason OSB can be sold at such a low price is that the wood is sourced from quick-growing forests from trees such as Aspen, Poplar, and Pine. Since the trees are cut into strands the manufacturer does not have to be so picky on the width and size of the trees and can use trees that otherwise would go to waste. This helps to keep the cost of raw materials down.
Due to wood being pressed so densely together OSB becomes very heavy. A typical 4 x 8 feet board OSB that is 1/2 inch thick will weigh around 54lbs. The weight of the OSB board will of course change depending on the thickness, size, and type of wood used for the boards.
We have OSB2 and OSB3 using for furniture, construction and packing.
