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.

Lowe's own installers won't install this

Would Not Recommend

Lowe's own installation team will not install this saying it voids the warranty. The warranty language of style select lvp says not compatible with acoustic underlayment. Lowes installation team considers this as acoustic and will not install it under Lowe's made lvp. Called the manufacturer directly (also Lowe's) and they said if the installer says no then no.

If it isn’t smooth to start with, don’t bother.

The first roll was ok. A little warped but usable. The second roll was so warped it had waves and caused the seams to overlap. I thought it might flatten out as I laid it down but it was a nightmare. I should have just taken it back but after spending hours cutting and placing it, I was not in the mood. I’m sure it will cause problems long term but this whole project has been a nightmare. Never again!!

Worked Well

Would Recommend

This worked well under the laminate but unfortunately the laminate was defective and had to be returned so this roll that was cut up for under the flooring was wasted. Otherwise it did work well.
