MDF or Medium density fibreboard in carpentry
MDF or Medium density fibreboard is an engineered wood product formed by breaking down hardwood or softwood residuals into wood fibres.
Basically, the MDF is made from leftovers or low quality wood and timber, then is glued and pressed together.
MDF has replaced solid timber as a low-cost alternative in a wide range of applications across industry.
The majority of MDF is mainly composed of softwood, although some brands may contain a higher percentage of temperate hardwood if this is locally available to the manufacturer. High levels of hardwood can be found in MDF board from outside the UK and Ireland.
Sanding the MDF can be dangerous thou, always wear a dust mask and keep windows open for ventilation.
