Fiberboard

Fiberboard is a type of engineered wood product that is made out of wood fibers. Types of fiberboard (in order of increasing density) include particle board, medium-density fiberboard, and hardboard. Fiberboard is sometimes used as a synonym for particle board, but particle board usually refers to low-density fiberboard. Plywood is not a type of fiberboard, as it is made of thin sheets of wood, not wood fibers or particles. Fiberboard, particularly medium-density fiberboard (MDF), is heavily used in the furniture industry. For pieces that will be visible, a veneer of wood is often glued onto fiberboard to give it the appearance of conventional wood.
Fiberboard is also used in the auto industry to create free-form shapes such as dashboards, rear parcel shelves, and inner door shells. These pieces are usually covered with a skin, foil, or fabric such as cloth, suede, leather, or polyvinyl chloride, often referred to as vinyl or PVC. PVC can be stamped with a pattern to resemble leather, and is often cheaper than leather, which makes it an ideal candidate for use.
Glued laminated timber

Glued laminated timber, also called Gluelam or Glulam, is a type of structural timber product composed of several layers of dimensioned lumber glued together.
By laminating several smaller pieces of wood, a single large, strong, structural member can be manufactured from smaller lumber. These structural members are used as vertical columns or horizontal beams, as well as curved, arching shapes. Connections are usually made with bolts and steel plates.

Hardboard, also called high-density fiberboard, is a type of fiberboard, which is an engineered wood product. It is similar to particleboard and medium-density fiberboard, but is denser and much stronger and harder because it is made out of exploded wood fibers that have been highly compressed. Consequently, the density of hardboard is 31 lbs. or more per cubic foot and is usually about 50-65 lbs. per cubic foot.
It differs from particle board in that the bonding of the wood fibers requires no additional materials, although resin is often added. Unlike particleboard, it will not split or crack. It is used in construction and furniture. Hardboard is produced in either a wet or dry process, which produce a panel called S1S or S2S respectively. The wet process leaves only one smooth side, but dry processed hardboard is smooth on both sides.

Pressed wood is any engineered wood building and furniture construction material made from wood veneers, particles, or wood fibers bonded together with an adhesive under heat and pressure.
Particle board

Filed under Definitions
Particle board, or particleboard, (or chipboard in the UK, Australia and some other countries) is an engineered wood product manufactured from wood particles, such as wood chips, sawmill shavings, or even saw dust, and a synthetic resin or other suitable binder, which is pressed and extruded. Particleboard is a composite material.
Particleboard is cheaper, denser and more uniform than conventional wood and plywood and is substituted for them when appearance and strength are less important than cost. However, particleboard can be made more attractive by painting or the use of wood veneers that are glued onto surfaces that will be visible. Though it is denser than conventional wood, it is the lightest and weakest type of fiberboard, except for insulation board. Medium-density fibreboard and hardboard, also called high-density fiberboard, are stronger and denser than particleboard.
