Tiling over HomeAdvantage Subfloor
I have just installed a second subfloor for a bathroom remodel. I will be tiling the whole floor and the custom shower. The HomeAdvantage product is from HD and is basically a good quality, dense, chipboard/glue type subfloor – very heavy.
The marking on the product says an underlayment must be used for non-textile coverings like vinyl tile and ceramic tile.
My plan is to use roofing felt followed by expanded metal mesh and thinset, followed by the tile.
I would appreciate any suggestions on a better method. I prefer not to put in lauan or quarter inch backer board, but am considering backer board may be the best choice. Money is not the object. Floor thickness is, as I am also installing suntouch in-floor heating wire.
The shower, of course, will be different as I will be installing nobleseal TS over a mud base, which will also probably be over backerboard.
Thanks for any suggestions.

I'm not sure that I would see and advantage of using wire lathe and mortar, versus just using the backer boards. (So long as the backer is properly secured.)
Support our Troops. Bring them home. Now. And pray that at least some of the buildings in the green zone have flat roofs, with a stairway.
I would go with Ditra. You can set the floor heat, lay the Ditra and start setting tile the same day, and it only adds ~1/8".
I see a conflict between heating wire and the expanded wire lathe mesh. Go with Ditra or Hardibacker

OK.
I am thinking about only Ditra and backerboard at this time. The wire mesh was a throwback to previous thinking.
It is all becoming clear to me now!
