Plywood has several advantages over natural wood, especially its dimensional stability (the measure of how much a material’s dimensions change due to temperature and humidity) and resistance to splitting. For these reasons, it is one of the most important wood products because wood is often used in environments prone to atmospheric changes or exposure to moisture. Plywood is also used for decorative purposes, particularly in cabinetry and furniture. It can be manufactured in curved shapes, called molded plywood, in which the veneers are bent and shaped as they are glued together. Typically, plywood panels range in thickness from 3 mm (about 0.12 inch) for all-veneer plywood to as much as 30 mm (1.2 inches) for lumber-core materials.
