chip board ok for wood floor underlayment?

We have gotten conflicting advice on if we can get solid wood flooring or must get an engineered floor because our subfloor is chipboard rather than plywood. They say that the nails or staples will not hold sufficiently to our chipboard subfloor so we must get an engineered wood floor. The others say that this information is old advice and that now the current thought is that it is ok to put a solid wood floor on a chipboard subfloor. Which is the correct advice?

The age old answer....it depends! :) Do you know what type of "chipboard"? Advantech subfloor will hold nails sufficiently, I don't think regular 3/4" T&G OSB will hold nails sufficiently.

I would guess we have regular 3/4" T&G OSB, but how do you tell? Our house is 14 years old. Looking underneath it says "potlatch oxboard, 23/32 inch 24OC"

Advantech subflooring is a fairly new product so if your house is 14 years old it is most likely ordinary OSB. If you really want hardwood floors instead of engineered you can get some special glue to glue the floor down as well as nail into the joists to help hold it down. You should check with a flooring shop for the best products to use with the wood floors they sell. Hope this helps you out.

Hardwood flooring can be put down over OSB but you should use flooring staples not nails. And it is recomended that you put down 13 Lb. felt with 4" overlay between the flooring and the OSB.
