MDF (Medium Density Fiberbord) is one of the finishes used for Kewlox panels.
MDF is a panel made of medium density fibres, manufactured from wood fibres which are mixed with synthetic fibres, so as to create a board when this mixture is hot-pressed..
Either untreated (reserved only for clean environments which do not have constant humidity) or covered with a layer of melamine (which is very easy to clean with a damp cloth).
These panels are 3 mm thick and therefore give a very low emission of formaldehyde.
