We used to call it Oriented Strand Board when it was invented in the 80s.
OSB is NOT the same as particle board. Different products.
OSB isnt particleboard. Although I guess you could compare it in a way. OSB is a board made with a type of chip. All glued together and pressed into board, then cut.
OSB is stronger than plywood.
Particleboard is fine sawdust glued together and then overlayed with a impregnated paper-either a paper and plastic composite or something similar. Counter tops are particleboard, unless you have granite or marble.
Thats a differt product all together its not partical board
OSB and particle board are two very different things.
Still call it OSB.

OSB is far better than particle board,, not the same at all... If you don’t believe me try using particle board for roofing underlayment and getting it past the inspectors.
