Floating wood floors are those that are installed without being attached to the subfloor. Instead these floors are attached to themselves. Most commonly these are attached by gluing together the tongue & groove of the flooring. Floating wood floors are most commonly installed in condos (where sound requirements exist), over concrete, or when being installed below grade (as the underlayment used under floating floors, creates a barrier from moisture). We try to avoid floating floors whenever possible, as glue or stapling is always the better option in our professional opinion.
