Ditra with UFH ?

[2020Tiling]

Have a floor to price up as follows ... ply floor kitchen 15mtrs 18mm ply no deflection. tiles are 600 by 400 trav.
was thinking of over boarding with 6mm hardy
then 6mm Insulation boards
ufh
screed
ditra
fit trav

Is this the correct way to do it ? also is it a must to install Insulation boards ? customer wants to keep hight down . and with adding ditra with ufh customer is worried they wont get enough heat getting through to the floor with all the above over the ufh? would ditra allow the heat through ?

I'd probably up the depth of the ply to 22mm Terry, ditch the haardiebacker, but use the insulation and ditra. No probs with heat transfer through the ditra mate.

Above sounds good to me.....

We have noticed more people using our MD200 mat for Kitchens, more output for the same area over the MD160 mat.
