MDF or Medium-density fibreboard is a man made wood that is free from natural defects. It has a smooth sanded surface and precision finish. MDF is very versatile and suitable for a wide number of internal uses such as internal joinery, panelling, boxing in, furniture, shelving, modelling, shop fittings, and architectural mouldings. At B&Q we only buy responsibly sourced wood. All of our MDF sheets are CE and FSC certified.
