- Blockboard —core plywood, of which the core is made of strips of solid wood more than 7 mm wide but not wider than 30 mm.
- Composite plywood —plywood, of which the core (or certain layers) is made out of materials, other than solid wood or veneers.
- Composition —description of constituent elements of plywood.
- Decorative plywood —decorative plywood is used where the appearance is most important: panelling and furniture. Exterior plywood Refers to the bonding quality: the adhesive used in exterior plywood is weather proof and the plywood can be used in exterior or humid conditions.
- Face, Back —the better quality surface of plywood is called the face and the surface opposite to face is back.
- 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, high-density fiberboard and hardboard. Fiberboard is sometimes used as a synonym for particleboard, but particleboard 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.
- Finished plywood —plywood further processed by sanding or overlaying.
- Fire properties —as a wood product, plywood is classified as a combustible material. The ignition temperature is 270¡C if exposed directly to a flame. If not, ignition does occur at a temperature of 400¡C. However, the performance of plywood in the event of a fire is very high, as the surface of plywood is carbonised, which protects the panel and slows down the burning process.
- 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 more dense and much harder because it is made out of exploded wood fibers that have been highly compressed. It is referred to as Masonite in the USA because that was the first brand to be marketed there in the 1920s (25 years after it was invented in England).
- Hardwood plywood —refers to plywood made out of hard wood tree species used, as beech, birch, Okoumé, etc. They can be mixed as well.
- I-beam —is a beams with an I- or H-shaped cross-section. The horizontal elements are flanges, while the vertical element is the web. The Euler-Bernoulli beam equation shows that this is a very efficient form for carrying both bending and shear in the plane of the web. The cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.
- Interior plywood —interior plywood is intended for use inside.
- Laminboard —core plywood, the core of which is made of strips of veneer, not thicker than 7 mm, placed on edge.
- Lay-up —arrangement of layers in plywood.
- Length of a panel —the panel dimension is in the direction of the grain of the face and back.
- Lumber or Timber —is a term used to describe wood, either standing or that has been processed for use-from the time trees are felled, to its end product as a material suitable for industrial use-as structural material for construction or wood pulp for paper production. In the U.K. and Australia, "timber" is a term also used for sawn wood products (that is, boards), whereas generally in the United States and Canada, the product of timber cut into boards is referred to as lumber. In the United States and Canada sawn wood products of five inches (127 millimeters) (nominal size) diameter or greater are sometimes called "timbers".
- Medium-density fibreboard (MDF) —is an engineered wood product formed by breaking down softwood into wood fibres, often in a defibrator, combining it with wax and resin, and forming panels by applying high temperature and pressure. It is a building material similar in application to plywood but made up of separated fibres, not wood veneers. It is denser than normal particleboard.
- Moisture properties —plywood has in general a moisture content of 7 to 8% when it comes out of the factory. This might of course change due to the ambient atmosphere. However, the cross bonding of its different plies significantly reduces the dimensional changes of plywood.
- Oriented strand board, or OSB —is an engineered wood product formed by layering strands (flakes) of wood in specific orientations. In appearance it has a rough and variegated surface with the individual strips (around 2.5 by 15 cm (~1 inch by ~6 inches) each) lying unevenly across each other in the direction of their grain.
- Overlaid plywood —plywood surfaced with one or several overlay sheets or one or several films such as impregnated paper, plastic, resin film, metal or decorative veneer.
- Pallet —is a flat transport structure designed to support a variety of goods in a stable fashion while being lifted by any mobile forklift or other jacking device. The goods are placed on top of the pallet, and can be secured to it by straps or stretch-wrapped plastic film. While the majority of pallets are made of wood, pallets manufactured from plastic, metal, paper can also be found.
- Particleboard (called "chipboard" in the UK and Australia) —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. Particle board is a type of fiberboard, a composite material, but it is made up of larger pieces of wood than medium-density fibreboard and hardboard.
- Plywood —is the first type of engineered wood to be invented. It is made from thin sheets of wood veneer, called plies or veneers. These are stacked together with the direction of each ply's grain differing from its neighbors' by 90° (cross-banding). The plies are bonded under heat and pressure with strong adhesives, usually phenol formaldehyde resin, making plywood a type of composite material. A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength.
- Plywood grades —plywood is graded by the quality of the outer plies.
- Plywood quality classification —plywood is classified by visual appearance of face veneers. The face veneers of different grades do not cause differences in the strength and stiffness of the panels. The grade of face veneers in one plywood sheet may be different: then the grade of better face is given first. Softwood plywood Softwood plywood is made out of soft wood tree species (maritime pine, spruce, etc.) It refers in general to structural plywood.
- Softwood —is a generic term used in woodworking and the lumber industries for wood from conifers (needle-bearing trees from the order Pinales). Softwood-producing trees include pine, spruce, cedar, fir, larch, douglas-fir, hemlock, cypress, redwood and yew.
- Structural plywood —structural plywood is used in building construction for sheathing on walls and roofs and floor underlayment. So it is often not visible after the building is done. Most structural plywood is made from softwoods and uses thick, low-grade veneers. For certain uses, like siding and concrete forms, may require a better grade face veneer.
- Veneer —thin sheet of wood not more than 7 mm in thickness. Sliced veneer is produced by slicing and rotary cut veneer by peeling.
- Width of a panel —the panel dimension at right angle to the length.
- Wood pellets —are a type of wood fuel, generally made from compacted sawdust. They are usually produced as a byproduct of sawmilling and other wood transformation activities. The pellets are extremely dense and can be produced with a low humidity content (below 10%) that allows them to be burned with a very high combustion efficiency. Further, their regular geometry and small size allow automatic feeding with very fine calibration. They can be fed to a burner by auger feeding or by pneumatic conveying.
