Other forms: plywoods
Plywood is a building material that's made from layers of wood that are glued together. This construction means that plywood is very strong and resistant to chipping or warping.
There are many kinds of plywood, and even more ways to use it. Plywood made from soft woods is used for sub-flooring in new homes and packaging of various kinds. Harder plywood can be made into furniture, walls, cabinets, stereo speakers, and sports equipment. The layers (or plies) in a piece of plywood are glued together with the grain direction alternating, which makes it sturdy even when it's thin.
