200 Sq. Ft. Cork Roll 48 x 600 Inch Cork Underlayment Roll Sound Insulation Mildew and Moisture Proof for Office Home School DIY Supplies(3mm Thick)

This is the second time I've ordered a roll of this cork underlayment to place under sheet vinyl flooring. It's great for dampening noise and temperatures, and provides a smooth surface. When placing it on the floor take care around the edges because they might rip if mishandled. The cork cuts easily with a box cutter and can also tear easily when pulling or pushing on it. It looks very nice, though, when laid out on the floor awaiting a top cover. The first cork went down a year ago and we haven't had any issues with it.

I am putting down a hardwood floor in an area I have reclaimed from the attic, and need a sound dampener because my wife said she could hear me walking around. Cork seems about the best, or so I came to believe. OK, so then which ones? Home D has some that are more expensive, rates higher. This one is cheaper by about half. I actually tried to order the one from H-D, but the delivery agent messed it up, and it got sent back after delivering the wrong package. Back to Amazon. So, I took a chance on this one (Amazon said they could deliver it next day, turned out next 2-days, but better than FedEx). Packaged about as well as anything I have ever received. Really. Got it unwrapped/boxed/unbubble-wrapped and glorious cork, Very Fragile. I guess some of the other ones may be stabilized somehow, this one is definitely as cut from the cork tree.But that is OK, as long as you handle it Very Gently, cut it with a Very sharp knife, up against a straight edge pressing down on it (or it will tear). Roll it out on the glue little bit at a time, you are not going to adjust it, use the tape stuff if you have seams, let it dry (I didn't). Works Fine. Just a bit harder. If you don't glue it down, you are going to tear it to little bits. H-D has cork glue. (Maybe Amazon too), about $25 at H-D for a gallon, which seems to be enough for this roll if you skimp a bit.

Before I write this review, the disclaimer is that I have NO IDEA what the characteristics of a role of thin cork are supposed to be. So, it could be it’s “behaving” exactly how it should. With that said…. This stuff is SO FRAGILE, and BRITTLE, that the sheer act of unrolling it causes it to break & tear. I’m using it as soundproofing that is being hung in sheets over the top of rockwool, but under drywall. The first product I used was exceptionally durable. I assumed all rolled cork was like that. I gave the product 3-stars specifically due to the fact that I could be using it in a way it was never meant to be used. I purchased this product because the price was better. But, even unrolling the cork, and using just 4X6’ sheets, the cork was breaking off constantly. I failed to see how even using it as “bulletin board” cork would get past this problem.With all that said, the product IS, in fact, what they claimed. 1/8” (I believe) cork. If these truly are the characteristics of cork rolls made in this fashion, and the customers who usually use it in what I’m assuming would be an educational role, are OK with that, and expect that level of fragility from this product, then it may suit your needs perfectly. It would be that a role of cork this size, once mounted on an axle, wouldn’t have the durability issues. But, even when cutting off a 4X4’ piece, it was EXTREMELY easy to tear, or puncture. Perhaps layered it would be good bulletin board material.I’m either completely naive, and foolish to even consider using this product like this as an insulation retainer and extra layer of sound proofing (in which case the review is worth of 5-stars), or this product does have major issues with durability. That’s about as honest of a review I could write. Short of that, like I said the product is technically “as advertised”.

Shipping was very prompt. Product was not good. I opened the box and tried to take out the cork but it ripped and crumbled. Wanted to use this as underlayment for our floor but had to return it. The return process was easy and my payment was promptly returned.

Used as underlayment for flooring thickness was perfect and reduced echo

Fragile, must have assistance to cut & move large sections. Will crack easily. Instead of stapling this material to moisture barrier we used double sided tape. Plan ahead.

I liked using two cork layers as subflooring. Easy to for DIY person to install. By mistake, i tore it a few times, but it was easy to fix using quality tape.

The package was damaged and the cork inside. I had to sent it back
