I hope you can help. We are going to be building a new house and the builder wants to use particle board for the floor. We have heard there may be possible health risks with particle board. We have also wondering if there is a substantial difference between plywood and particle board.

Thanks in advance

OSB (particle board) does 'out gas' more than plywood. This was an issue with us as we have allergies. WE went with plywood subfloor (more expensive) as well for cabinets (also more expensive). We also added a Heat Recovery Ventilator because it brings in fresh air while exhausting stale indoor air. Of course, we also had to add a large HEPA filter so the fresh air did not contain all the stuff we are allergic to. Then the furnace was upgraded to 2-stage blower so we can run it on low speed 24/7 and insure the house air is exchanged continually. The bath and kitchen ventilators all exhaust outside. We are in the last 2 months of the construction (we hope) so will see soon how all our efforts (and expense) have improved the living conditions for us.
PS: OSB used for exterior sheathing and roofing is outside the 'living envelope' so is not a problem.

some contractors put down a plywood subfloor ,then put p-board on top (makes for a quiet floor) p- board if its thick enough can be used as a sub floor ( 1-1/4"),but i would not want one, see if the buget will allow plywood or o.s.b....all wood type subfloors have formaldehyde.good luck
