Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [1] MDF is generally denser than plywood.
Fiberboard (American English) or fibreboard (British English) 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 or low-density fiberboard (LDF), medium-density fiberboard (MDF), and hardboard or high-density fiberboard (HDF).
Hardboard is similar to particle board and medium-density fiberboard, but is denser, stronger and harder because it is made out of exploded wood fibers that have been highly compressed. [3] The density of hardboard is higher than 500 kg/m 3 (31 lb/cu ft), [4] usually about 800–1,040 kg/m 3 (50–65 lb/cu ft). [5]

Norbord operates 13 OSB mills, 1 MDF (medium density fibreboard) plant, 2 particleboard (chipboard) plants and 1 furniture plant. Its OSB mills in the US are located in Minnesota, Georgia (2 lines), Mississippi, Alabama, South Carolina and 2 in Texas. In Canada there are 2 mills in Alberta, 1 in British Columbia, 1 in Ontario and 2 in Québec.
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. Different grades of particleboard have different densities, with higher density connoting greater ...
