Medium Density Fiber is a lower cost alternative to Veneer Core and/or Combi Core. With an extremely smooth surface, MDF and HDF (High Density Fiber) are very stable hardwood plywood substrates when constructed with a balancing face and back. Because the orientation of the wood fibers is random, this substrate has consistent physical properties in all directions thus creating a core that has minimal thickness variations. The screw holding capabilities are good, especially when used with special purpose fasteners.
In thin fiber core, up to 3/16” thick for a finished ¼” panel, DVC offers High Density Fiber as well as Medium Density Fiber core. Generally, thicker options are MDF unless HDF is specified by the customer.
