In fact it must be supported by a strong subfloor with limited gaps and it can bridge only small holes.
It was constructed to be a softer, warmer and quieter floor, which makes it a great fit for this major gathering space in the home. Floor covering, or finish flooring, is the surface that you see and walk on, not the subfloor (under the underlayment) or underlayment (between subfloor and finished layer). A minimal gap should be left between the flooring and the cabinets.
