Hi Guys,

Opinions please, upstairs bathroom, brand new 22m chipboard, new install. I have always gone with 6mm Hardie Glued and screwed, then cleaned up acrylic primed and wire layed on Hardie and taped down, then latex ed over with 2 Part SLC, then tile?

Customer/electrician has suggested Ditra then Wire then Tile, I always like to SLC my UFH wire/matt before tiling. I can't see the logic in pouring leveling compound over Dita as surely you'll lose the whole purpose of the decoupling membrane?

Thoughts please not doubting myself just can't see the logic in his option?

Thanks

if ditra is being used then should be on top of ufh and latex.
if floor is deflection free then thermal board, ufh, latex then tile would be my preference

if The customer wants to add uncoupling into the job then I would board with your hardie then fit a system like ditra heat, or vario pro, several others available. The wire goes into the mat then tile straight ontop

Would you think the decoupling properties of the thermal board not adequate and skip the insulation?

Personally I’m happy to use hardie or insulation board over floor boards, both uncouple. I wouldn’t bother with an uncoupler ontop of those, but if the customer wants ditra, then ditra heat makes sense here
