Plain MDF

Plain MDF comes in thickness ranging from 3mm to 25mm. Thin boards are ideal alternative to plywood with the added advantage of being smooth on both surfaces and free of grain features which can show through paint finishes and thin foils lamination. Thin boards can be used for wall and ceiling paneling,   as skins for flush doors, partitioning, office screens, furniture mouldings and built-in furniture.

The thick boards can be used for a wide range of furniture such as tables, cabinets, windows, ceiling, partitions, doors, frames and many other possibilities.
