is a thick premium underlayment that is primarily for use under hardwood and laminate floors. The unique engineering of this underlayment allows it to interact with the floor system itself in a manner that produces a sound similar to that of traditional wood flooring. In addition to use under floating floors, this underlayment significantly reduces noise transmission while providing insulation and stability.
