Noble EZ

My local rep comped me most of a small roll of this stuff a while back. Basically it's an A118.12 crack isolation membrane that is designed for light duty applications.

It comes in a 3 foot roll and a 6 foot roll. It's about 1/32 inch thick and you can adhere it with one of their glues or a latex modified thinset. I prefer the thinset but was going over osb on one project and they require the glue. It seems to flop down well and the edges aren't trying to peel up on you.

Why does any of this matter?

It's priced to compete with uncoupling membranes and it basically is Noble's uncoupling membrane. It does everything they do plus gets a "high performance" rating on the crack test.

I've switched over to this stuff as my standard tile underlayment. I still use uncoupling membranes (Spider Web II is my fav) and use them when I need the 1/8" height.

Dal sells a relabeled version of this stuff called Dal RCI. (Pictured below)

*It should be noted that the crack test was performed with their EXT glue. Glues move a little better than thinsets so the performance would probably dip some when thinsetting it down.

Nice info there , Jim .

It looks like the EZ membrane --outperformes the uncoupling membranes -- ... I wonder how ?

I'd not heard of that membrane, Jim, and wonder why they've come out with that. Their NobleSeal CIS will past the same A118.12 testing and also get a High Performance rating.

If I needed a crack isolation membrane because I needed to bridge a crack in concrete I would still use CIS.

I don't look at Noble EZ as a replacement for CIS. I look at it to compete with uncoupling membranes. It's priced similar to uncoupling membrane and I would use it over wood subfloors. CIS is more expensive than uncoupling membranes and, in my opinion, is overkill for a wood subfloor.

Jim -- Just a quick question. Do you believe the EZ membrane (made from PVC) will hold up as well as a CPE membrane over a long period of time? Of course, it's not for waterproofing, so maybe it's just as good in an uncoupling application.

Well,

I don't think thinner is better when it comes to uncoupling. I think Jim intimated that. Rick mentioned PVC, which will stiffen as it ages, but as he mentioned, it might not affect the "uncoupling" properties of the membrane. That is . . . once we understand what uncoupling is.

I want to make it clear that this isn't an uncoupling membrane, it's a thin Crack isolation membrane for residential use.

I don't know enough about cpe vs pvc to comment about how it will perform.

Jim , I think the confusion with the Noble EZ is coming from -- featured as '' outperformes the uncoupling membranes '' .

I still wonder how a full bonded sheet membrane could be compared with an uncoupling one ? Is there something definite about the uncoupling membranes ?

The way I see it is if we're comparing names and categories- then it wouldn't compare with an uncoupling membrane. It would compare to other CI membranes.

But I look at it from a function standpoint. What function does an uncoupling membrane perform? I use uncoupling membranes over wood subfloors. What does an uncoupling membrane do that a crack isolation membrane doesn't do? What function does it perform that a CI membrane won't?

Noble EZ is the only CI membrane that I'm aware of that is priced similar to uncoupling membranes. That's why I think that the two can be compared.

I'm not sure if I'm addressing your points though.
