Installing Hardwood Flooring
A contractor is planning to install a solid oak floor by nailing the 2-1/2 inch oak strips (3/4 inch thick) into the subfloor (3/4 inch OSB), but NOT into the joists. I have always thought that the typical way to install the oak is to nail or screw them into the joists (through the subfloor). The reason the contractor wants to do it this way is that the joists under half the room go in a different direction than the other half and we want all the oak strips to go in the same direction as the rest of the floor. (My gut feel is that OSB will not hold the nails or screws tight enough, but I am not sure).
Is this type of installation strong enough to hold the oak flooring over many years of use in a kitchen?
