Timber - Sheet Materials - MDF - Types & Uses
As a consequence of the manufacturing process, medium-density fibreboard (MDF) is an extremely versatile building material. It is strong and dense, consistent in strength and size, and has a lesser tendency to spilt as there is no grain.
MDF is an engineered wood-based sheet material made by bonding together wood fibres with a synthetic resin adhesive. It is extremely versatile and can be machined and finished to a high standard.
It is an excellent substrate for veneers, it shapes well, it has stable dimensions i.e. it won’t expand or contract like wood, and some varieties are less expensive than many natural woods.
Standard MDF offers a smooth board, which is suitable for cutting, machining and moulding. Because of the smooth surface
of the wood a router can produce smooth, crisp profiles with no splintering, burning or tear-outs. It can also be painted, veneered, sprayed and is widely used in the furniture trade. As a result MDF has replaced solid timber as a low-cost alternative in a range of applications across the construction industry.
For more demanding situations MDF is available in moisture resistant (especially for kitchens and bathrooms), flame retardant, high density and exterior grades.
Veneered MDF and Flexible MDF are specialist boards. The range of veneers, where one or both faces are veneered, include ash, oak, pine, and sapele amongst others. Flexible MDF is a sheet with a grooved underside allowing use in many applications.
MDF is also available as mouldings for skirting boards, architraves, window boards, and door linings.
