Last Answer : It depends on what you have on the other side of the OSB. If there is land or non-residential space, I would choose some insulation, such as cotton wool or anything similar. Then as you write. ... similarly, without tiles, but even there could be. A vapor-permeable foil is still under the OSB board.
