This page last reviewed July 1, 2015
This site provides a brief definition of terms used throughout the composite wood products ATCM webpages.
Wood products comprised of a resin matrix in combination with a wood fiber reinforcement. Composite wood pertains to, but is not limited to, particleboard, plywood, medium density fiberboard, composite veneer and oriented strandboard.
The wood of a broad-leaved tree, (e.g., oak, aspen, birch etc.) either deciduous or evergreen.
Medium Density Fiberboard
A building board made by compressing finely ground wood chips in urea-formaldehyde adhesive. Available in sheets from 8 to more than 30 mm thick.
A board made from nonchemically processed dry wood particles of various shapes and sizes and either synthetic or natural adhesive material.
A board composed of a number of thin layers of veneer united under pressure by a bonding agent so that the grain of each layer is at right angles to that of the neighbor.
Thin sheets of wood peeled or sliced from logs for use in the manufacturing of wood products such as plywood, laminated veneer lumber, or other products.
A thermosetting resin manufactured by heating together urea and formaldehyde. Palecolored or water-white and translucent. It can, therefore, take delicate dyes and tint. It is non-flammable and is resistant to weathering and fluid attack.
A thermosetting resin produced by the condensation reaction of phenol and formaldehyde. Phenol-formaldehyde resin emits much less formaldehyde gas than urea-formaldehyde resin containing composite wood products.
