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. Reviewers note it remains stable and doesn't crimp or warp like thinner alternatives. A few mention concerns about pricing or unclear instructions, but most consider the quality and performance well worth the investment.
