BOARDS AND PLYWOODS

Plywood is a wood product manufactured out of many sheets of veneer, or plies, pressed together and glued, with their grains going in opposite directions. Plywood tends to be extremely strong, though not very attractive, and is treated in many different ways depending upon its intended application. Because of the way in which plywood is constructed, it also resists cracking, bending, warping, and shrinkage, depending upon its thickness. Plywood is also referred to as an engineered wood, although it is made from a composite of wooden materials, and various forms of it have been made for thousands of years.
