Medium density fiber board (MDF) is a non-structural, interior product.

Although MDF uses much of the same types of recovered and recycled wood waste as Particleboard, it is refined differently using a high energy refiner that acts like in a steam pressurized “digester” allowing the raw material to become softened and to actually change physically and chemically. MDF is an excellent substrate that is very smooth, stable, and flat and offers superior design flexibility.
