Friend of mine who works for Wisconsin log homes says he can get me some Schluter-ditra to put on top of cement board before I put the ceramic tiles down. Anyone ever hear of this or use it?
 
Seems like overkill if your base and backerboard are adequate. Are you laying down at least 3/4" plywood, then 1/2" cement board? If yes, then this could be gilding the lily.

The Ditra is intended to take the place of cement board. It is an underlayment. Using it in addition to cement board would be redundant. I don't think it will hold up to the heat a stove will produce, it's plastic. I did not use it under my hearth for that reason. Cement board works just fine.

Thanks for the response. I was thinking the same way. The hearth will be pretty much flush with the carpet. Will be using micore sandwiched between two layers of durock. The tile on top of that. Sound okay?? It's an Englander #30.
 
It is essentially an anti fracture membrane that creates a layer between the substrate and the tile to uncouple the bond between the 2. It is used in normal flooring installation like over a concrete subfloor so that any cracks or movement in the substrate do not continue or create cracks, if the substrate moves. into the tile or finish layer. It can also be used as a vapor barrier/moisture mitigation layer or a waterproofing layer dependent on the install. I don't think it would be a good idea to put on the hearth as Webby said as it is def not resistant to heat and does nothing for R value or insulation.

Thanks again. We are off to get thinset and grout. Will try and post pics when we are further along.

For the Englander 30 you can go with 4 layers of 1/2" Durock NexGen or if you want to use Micore, put it on the bottom, under the two layers of Durock NexGen. That will give you a more rigid tiled surface for the stove to sit on.

Wish I had read that a few hours ago. I put the micore between 2 layers of durock. Should be okay right? Tonight I am sitting in the recliner cutting I inch spacers from some copper pipe. Cost of individual pieces $1.49 each..10 foot pipe $ 10.00. Any idea how many I need for each sheet of cement board??? I have bottle of arthritis strength aspirin next to me...thinking my hands are going to get sore :)
 
What are you intending to do with the spacers? What is you plan?

1 inch copper spacers to mount cement board (durock) to wall studs behind stove. That will give me the 1 inch air gap I need right? On the durock, we are putting imitation fieldstone. If this sounds wrong please tell me. I really want to do this right Thanks for any help and suggestions.
 
That's a fine way to reduce Clearances, assuming your stove allows for clearance reduction with a shielded wall. What stove is it?
 
Englander 30-nch This is what the spacer, durock will look like

Is this a corner or flat wall install? What is the goal, to reduce clearances? If so, what will be the distance from the stove to combustibles in the rear and sides?

Sorry took me awhile, computer was out. This is a corner install. According to manual and James at customer service with the 1 inch air space, the cement board and the fieldstone I only have to have a distance of 12 inches from protected surfaces (which is the wall behind all that stuff) We will have about 14 from the corner of the stove. I called customer service twice (on wife's insistence) just to be sure I had the numbers right. We will be using a double wall stove pipe. If this sounds wrong...stop me before I drill that first screw
 
That is correct.
