These can be grouped within three broad classifications:
These are composed of layers or strips of solid wood glued together in simulation of solid wood, viz. plywood, laminboard, blockboard, battenboard, each layer being at right angles in grain direction to the one above or below.
Commonly known as chipboard, they are composed of wood chips bonded together with synthetic resin glue and pressed or extruded into rigid sheets.
These are composed of wood fibre macerated in water and pressed at high temperatures, often with a little resin, into sheets and boards of varying densities, according to the degree of heat and pressure applied, viz. hardboards. softboards, and medium density fibreboard. The later, MDF, is rapidly superseding both particle board and plywood in industrialized production of furniture.
