What Customers Are Saying
Customers overwhelmingly praise this underlayment for significantly reducing footfall noise, providing moisture and mold resistance, and simplifying installation under vinyl flooring on concrete. Many highlight the cushioned comfort underfoot, especially in high-traffic areas, and appreciate how the built-in adhesive strips and overlapping edges make it easy to lay, cut, and align without additional tape.
