That's like saying Iron and Copper are similar if not the same.. Paticle board and OSB are similar if not the same,
No it is not,
no, particle board doesn't have the structural properties of either oriented strand board (osb) or plywood.
I was watching a documentary on the rebuilding of hurricane damage homes on the east coast. I was surprised they were using OSB for the walls and roof. I always thought plywood was superior, but after seeing that, I don't know.
Agreed. I would never use particle board in subflooring, or anywhere else moisture can get to. Particle board is terrible for absorbing water.Unless they have come up with a new formula for Particle board - it should never be used for sheathing & no it is not common anywhere I have been
Some cheap builders & most mobile home manufacturs use it for subflooring, but I don't recomend that
Where is it safest to use - subflooring & cabinet boxes where the house has plenty of time to air out from the off gassing & there is minimal chance of moisture getting to it
