MDF (Medium Density Fibreboard)
An engineered wood product manufactured from wood fibres and resin, forming smooth, consistent boards with no grain. Widely used for interior joinery - skirting boards, architraves, door casings, shelving, and cabinet doors - because it takes paint well and has no knots. MDF is not suitable for external or high-moisture environments; moisture-resistant (MR) MDF should be used in bathrooms and kitchens.
