Blockboard is a type of plywood that is engineered in a special way. It is pressured in such a way that the softwood(pine,Poplar wood,paulownia wood) strips are found between
two layers of the wood veneers in the core of the sheet. This contributes to the dimensional stability of the board. The presence of softwood
strips ensures that the board is able to hold nails and screws better than the other engineered boards. Though it is lighter than plywood, it
does not split or splinter while cutting because of the presence of softwood in its core.
