Nice ProductReview by Angelino A.
Ease of Installation
We installed new Luxury Vinyl Flooring and we used your underlayment for our water barrier and soundproofing for the floor. Your product was so easy install that we finished our project a day early just because we considered more time for the underlayment. Nice product and would recommend to a friend.
