    • Nice heavy roll of soft underlayment.
This product is 300 ft² of soft, black, underlayment to be placed down on the floor before any flooring choice. It provides a good seal to protect the wood or concrete underneath, and it also adds a little softness to the people stepping above, even if hard tile is to be placed on top. We ended up using this to completely gut and redo a bathroom in our house. It was easy to use, in fact all underlayment is a very simple job to do. But it maintained a tight seal over the bare wood that was left under our floor. It installed properly without any lumps or any adjustments needed once it was set down. It was a great start to ultimately having the tile placed above it, and definitely helped with making the floor a little more secure, as well as sound and heat proof. Instead of getting a huge draft in there, especially when in the shower, for some reason it helps trap the heat in just a little better. Overall, this roll of flooring was successful and continues to hold strong, even when put in by a complete amateur like me! ... show more

    • Worked Out Fine for Me
Review Image by BIN929 BIN929
The quantity of this roll is awesome. It is easy to work with. Requires a sharp pair of scissors or box cutter. I was told by the person showing me how to do the install, that this is the most thin underlay material they have seen or used. I had one rip and it was my own fault. I would purchase this again. ... show more

    • Foam Underlayment. Great For Small Job We Did, Does Tear Easily!
I haven't used the entire roll of this underlayment yet. We had to replace the floor in our bathroom due to a leak. I used this underlayment under flooring that has a rubber back. The underlayment is easy to cut and place where needed on the floor. It does have a tendency to move toward the area where the flooring is being laid (it is lightweight). I did tear a couple of holes in the underlayment as I tapped (beat, whatever) the flooring joints together. The finished floor feels more padded by using this material than other underlayment's that I have previously used. This was an adequate underlayment for the small job that I completed. I have a larger room to convert to wood flooring and will update this review after the application of this underlayment there. At this point, after completing the smaller bathroom floor, I am happy with this underlayment and pleased that the foam material provides a moisture barrier. ... show more

    • Untouchable underlayment
It looks good but little force broke the foam easily. They used tape surrounded to hold the label and I tried to remove the tape. The layer easily torn by the tape. During installation, tapping (to eliminate the gap of the hardwood) sliding the hammer on the sheet can tear off the foam. Very untouchable. I will not use again. ... show more

    • Thin, really thin.
I needed something to put under some click together vinyl flooring in a small guest house. The underlayment is really thin and isn't the most durable. If you need a little "extra" layer under laminate flooring, and you can work carefully, this stuff will work. It lays flat and is easy to cut into shape. Other tan that it seems to be a no frills thin foam underlayment. It will work for what I'm using it for, a small 175 sqft guest house. If I was going to do anything larger, I'd get something a little more durable. ... show more

    • Great underlayment!
I've tested a few different underlayments and this one is on top! It's thick, rubbery, material! More padded than the others! Lays down easy! Great quality! Better insulation properties! Great stuff!

    • Huge Roll

The wood under my laminate flooring in my RV is soft and rotting. I have to replace entire floor, and put new laminate. I ordered this to go on top of the wood and under the laminate. You get a huge roll for a competitive price point. I have only used a small amount as a test run to make sure the quality is up to par. I need something that will help keep as much moisture out as possible. The foam is a bit thin and fragile. I'm still on the fence about using this for the entire floor, because once it's done, I don't want to have to do it again due to low quality under lay. I have tested a few others that seem more durable, so I think I will opt against using this for the RV flooring. I will keep on hand for smaller, less permanent jobs if any arise. It's a shame, I have a huge roll and it's the perfect amount for what I need, just will not work. I'm disappointed! ... show more
