Blockboard is a type of plywood that is engineered in a special way. It is pressured in such a way that the softwood 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.

However, it tends to absorb and retain moisture. So it has to be used with caution in places where it is likely to get wet. Since the glue used to press the plywood under high pressure to make standard blockboard is only good enough for interior use, it cannot be used in the exteriors. But you do have special grade block boards that are made using special glue, that is suitable for exterior use and they are water resistant as well.
