Plywood More than 90 percent of furniture made today contains some plywood. Plywood has some definite advantages over solid wood. Because plywood is made by gluing several thin layers of wood together with their grains at right angles, it often is stronger than solid wood. Large, flat surfaces, such as table and cabinet tops, and curved wood pieces often are made of plywood because it can be bent and molded. It is very strong as a result of its construction, and resists checking, splitting and warping.
Plywood comes in a wide range of sizes and thicknesses.
Plywood may be made with a variety of cores and ply materials. Hardboard Hardboard is made from refined wood fibers locked together with adhesives, steam and pressure. Standard is strong and has good water resistance. It often is used in furniture construction. Tempered hardboard has been treated chemically and with heat to increase its stiffness, hardness and finishing properties.
