Subfloor Thickness w/ 3/4' Hardwood (white Oak)
I am planning on getting 5" Quartersawn 3/4" thick hardwood flooring installed in my home.
The subfloor in the house is currently 1/2" Plywood Sheets. I though I read that 5/8" or 3/4" plywood subfloor was recommended for hardwood. If that is the case I could add another layer as underlayment. Obviously want to keep the height to a min so not sure if 1/4" or 1/2" would be suitable.
Also, I can either add more nails or screw down the existing 1/2" subfloor to the joists. Is screwing preferred over the spiral flooring nails? Want to make sure the floor is as solid and sound as possible.
