Insulation board or Dtra matting on new sand/cement screed

[Mortorman]

Hi Guys, my coservatory is going to be screeded on tuesday to a depth of 4inches, my plan was to leave it for one month, then prime twice, install 10mm insulation board on flexible adhesive, lay UFH wire, Latex, then tile....... Does this sound like the best way to go to you pro's? someone suggested thati should lay ditra matting, the the thing is that i thought that insulation board would do a similar job to the ditra ie:acting as a slight deflecter. Or should i install both?

I will be tiling it with Travertine.

Thank you very much in advance

I would recommend a ditra/decoulpling membrane for the Travertine...

Thanks Whitebeam, and like bugs would you suggest this go.......... primer, insulation board, UFH Wire, Latex, Ditr, tile? I had no idea there was so much involved in tiling, am really glad i decided to check it all out before i do it.

Cheers mate
