SupaWood® is PG Bison's exceptional medium density fibreboard (MDF). It offers excellent structural strength with superior screw-holding capability and machinability.

This engineered MDF blends the advantages of manufactured board with the natural properties of solid timber, allowing for most traditional wood working techniques.

A versatile panel, SupaWood®’s homogeneous construction allows for moulding, embossing, deep routing and edge profiling and is perfect for both domestic and commercial use.

Comparison with natural woods

MDF does not contain knots or rings, making it more uniform than natural woods during cutting and in service. However, MDF is not entirely isotropic, since the fibres are pressed tightly together through the sheet. Typical MDF has a hard, flat, smooth surface that makes it ideal for painting.

MDF may be glued, doweled or laminated. Typical fasteners are T-nuts and pan-head machine screws. Smooth-shank nails do not hold well, and neither do fine-pitch screws, especially in the edge. Special screws are available with a coarse thread pitch, but sheet-metal screws also work well. Like natural wood, MDF may split when woodscrews are installed without pilot holes.

Benefits

  • Isotropic (its properties are the same in all directions as a result of no grain), so no tendency to split
  • Consistent in strength and size
  • Shapes well.
  • Stable dimensions (won't expand or contract like wood)
  • Easy to finish (i.e., paint)
