Use of Ditra Matting

[Kevboy]

I have just looked at a job where the customer has a solid floor, wants u/f heating and limestone or travertine tiles.
I was going to lay insulation boards, then Ditra followed by heating (self levelling) then tile.
Would this be acceptable or overkill, as floor is solid.
I've read that some tilers put the Ditra matting on top of the heating.
Is there a right way of doing this sort of job - please discuss

Insulation boards then ufh, slc and then ditra would be the way I would fit....

hi kev have you worked with stone or ufh before ?

 

[Protilers]

Hello mate......I will play devils advocate.....

so.......please could you define "solid".......for us all?

secondly...limestone and travertine are the softest of all sedimentry stones........therfore they need to be potected from expansion and contraction....
insulation boards are related to u/f.....but a decoupler can come before or after the heat mat........and in some instances an insualation board can act as a decoupler!!!!

hope you are now clear........best of luck with your job.......

all the best and nite nite.......

The ditra on top of the UFH would be my choice.

Ditra can be layed either above or below the heat mat however it is more effective when used above the UFH

so

Insulation
UFH
SLC (I assume this is electric UFH?)
Ditra
Tile
