Plywood can be used for many different purposes. Interior plywood comprises furniture and wall paneling, while exterior plywood is appropriate for kitchen fitments and applications around showers and bathrooms. Another type of plywood is structural plywood, which is manufactured for applications where strength and durability are the primary factors. Structural plywood is used in the construction and building industry. Most commonly plywood is used for formwork applications due to its strength, stability and tolerance to changes in temperature and moisture. Finally, marine plywood is used where moisture resistance is needed. Plywood can also be used for transport and boat construction and packaging manufacture.
