Apologies in advance if long winded and repeating myself... Have already bought 600 x 400 x 12 Marble tiles to cover 57 square metres of floor area (+10% for wastage). This area will be split over 4 areas (Living Room, Diner/Kitchen, hall and Garage (converting garage to a front room within next month). The Living Room, Diner/Kitchen and hall is a wooden subfloor 2" X 8" joists and 16" between joist centres and with 3/4" 'green boards' (have been adviced these 'green boards' are moisture resistant) on top. The house was built about 8 years ago. Garage, yet to be completed, has a concrete floor and is 300mm below current Wooden subfloor. My intension is to bring the garage floor up level with wooden subfloor with concrete, so concrete and wooden subfloor are level and "meet" at the Garage entrance door. also want the Marble laid brick pattern and flowing into all rooms with no pattern changes at doors to each room.
My question is... as I want to put in electric underfloor heating (UFH) over all the ground floor... do i need to use Ditra Matting as I will be using 10mm XPS floor insulation (Hard Polystyrene Home Page ), UFH, Leveling latex, flexible adhesive then marble tiles. So I am thinking leave out the Ditra matting all together as the tiles are not in contact with the subfloor (as have Latex, flexible adhesive and the thermal insulation below tiles).
One tiler said use Matting and another saying I'm introducing something that can go wrong (the Ditra).
What do you Guys think should I use ditra as it is only used for subfloor movement but as per above I'll be using 10mm hard insulation polystyrene boards? Would the subfloor expansion/contraction come through the insulation polystyrene boards/latex/flex adhesive and crack my tiles? And what about where the concrete and wooden subfloor meet again I'm thinking as long as joint is reasonably level the 10mm hard insulation boards should not transfer any movement to the tiles?
Thanks in advance.
