Nature Prints Floors Inc distribute 2 types of acoustic underlayment: Silent Blue Sound & Moisture Proof Underlay and Silent Blue Moisture Proof Underlay.
Since floating floors are not attached to the subfloor, they can expand and contract. Underlayment is necessary to create a sound barrier between a subfloor and laminate or engineered wood flooring. It protects great from any moisture, conceals minor sub-floor imperfections and is perfect as a sound barrier.
