Hi, just about to embark on fitting my new floor to 1st for room. The existing floor is pine timber nailed to timber joists. I'm putting 9mm plywood screwed down into this, then 4mm sound insulation roll. Then the new floor boards on top. The floor boards are click fitment.
My question is should I glue any of this or just float it?
