Er indoors has decided she doesn't like the carpet in the living room, and
she wants a nice wooden floor, not laminate and not engineered wood, but
solid oak floor.



Probably not what you want to hear ... but I would use a quality engineered
floor with 7mm veneer, so will re-sand as much as solid wood .... and apply
fully glued at joints, but laid over thin closed cell insulation as a
floating floor.

If tiles and & floor are good and level enough a 2mm closed cell insulation
would do.

I have laminate upstairs and engineered on all ground floor rooms .. all
laid fully floating.
