Plywood consists of an odd number of thin wood veneer sheets with formaldehyde glue sticking them together. Pressure and heat are applied to the wood veneers to stick them together and create durable plywood sheets. These sheet materials can be used in many applications, including building and furniture construction.
Lighter and less dense than natural wood, plywood sheets can nonetheless look like solid wood and can be customised with various types of wood as the top face. Panels of plywood are vital because the wood grain is alternated on each layer (cross-graining) to create a more robust material that is less likely to warp.
Plywood is a versatile material which can be used for a wide range of different projects. Different types of plywood lend themselves to various uses, such as roofing, furniture making, and flooring.
For example, panels of softwood plywood (made from pine, cedar, spruce, fir, or redwood timber) are ideal for construction and packaging. Meanwhile, hardwood plywood (made of mahogany, birch, poplar, beech, or oak timber) is a more robust and durable material used for factory walls, floors, or heavy-duty containers.
Another type of plywood is marine plywood because it can be used for boats or wet environments. Marine plywood is highly durable and resistant to water, so it can be used for these applications.
