The composition of blockboard is very different from other engineered woods such as plywood, MDF (Medium-density fibreboard) or Particle boards. It is made from solid blocks of wood at its core, sandwiched between layers of wood veneer (usually single layer of ply) on both its front and back faces. The difference in the way blockboard is made, gives it interesting characteristics and functionality.
Advantages of Blockboard:
Lighter in weight Lesser tendency to sag or bendCosts LessBetter than Particle Board and even MDF
