Medium Density Fibreboard
(MDF)
An ideal alternative to solid wood and plywood, Medium Density Fibreboard is an engineered wood composite board that is rapidly replacing other materials in the wood-based product market. Its advantages include high strength, ease of processing, good weathering properties, and an ability to be made from a wide variety of fibrous materials. As an extremely versatile product, Evergreen MDF is suitable for numerous applications including furniture, speaker boxes, and doors.
