## Description

Unison 2-in-1 Underlayment for laminate and engineered wood flooring is designed with 3/32 in. polyethylene foam for cushioning and a 2 mil thick top film to protect floors from harmful moisture vapor. Designed for on- or above-grade applications, as well as below grade when used with a moisture barrier. It's easy to install with a plastic overlap and adhesive strip to join multiple rolls. Unison's foam construction also reduces everyday surface noise.

Review: Great underlayment in the basement - After recently taking on the responsibility for raising my two boys (3 and 9 years old), I found that my living arrangements weren't going to work. My parents kindly decided to help out by letting me build an apartment in their basement. The Unison 2-In-1 underlayment was the perfect solution for breaking direct contact with the concrete. I used it not only under the laminate flooring, but under the free-floating vinyl in the bathroom and kitchen too. Not only does it make bare feet in the bathroom reasonably comfortable, it also softened the surface considerably. And while the laminate floors require socks at a minimum, they are also less chilly than they should be. We had originally been thinking about furring strips with narrow cavities and more substantive insulation, but with only 81" in the highest areas and considerably less under the ducts (especially with drywall cladding), we realized we would need every inch possible. This material was the perfect solution. While a little more insulation might have been nice, there is no way we could have found better insulation at 3/16th of an inch. And after discovering just how comfortable the vinyl floors are with this underneath, I will never lay another vinyl floor without it. It really makes for a very nice combination of softening the surface and making it quite a bit warmer - very efficiently reflecting the heat from your feet, right back through the heavy vinyl surface. And of course the price is unbeatable. I started this project having to buy two rolls from Home Depot - at $25.95 per roll. I bought the last four rolls here on desertcart for $14.95 per roll. With desertcart prime my shipping was free and they were here in just a couple of days. It seems odd to buy building materials online and indeed for many materials it really isn't cost effective, but I have learned to check here first, because you never know.
Review: Very good product at a great price - We could have gotten a comparable product at a local big box store but the cost was $7/roll higher. We read the reviews of the Roberts underlayment and decided it was good or better than what we could get locally and since the shipping was free it was an easy choice. It lays down easily and when the tape is pulled it adheres to the sheet next to to very well. My only complaint is that even with a new blade in our knife it was hard to cut small pieces off at the wall. That said I would definitely buy it again if we do another hardwood floor ourselves.

Used this to provide a water proof barrier per the luxury vinyl plank warranty installation instructions. Worked great, helped to give a soft quiet waterproof floor.
