Topps tile ufh and hardiebacker

[GoneGuy]

on a job at the moment and having a conversation with guy I’m subbing to about order of fixing.
Weyrock boarded floor.
They want to go
6mm insulation
Warmup mat ufh
Slc
Dural decouple
Tile.

They also have hardiebacker boards on site
What would you guys recommend

 

[Uheat - Jake]

If they're having a decoupling membrane in the system then I'd recommend to go with a decoupling heating option like our HeatBase, that way you could have a thicker backerboard giving a better subfloor to work with.

I will not fix BCT and UFH together, the two do not mix.

Ok thanks for that I’ll tell the client

I was going to suggest, presuming they were porc, that durabase would not be needed as the thermal boards have decoupling properties. I'd still go decoupler with stone and ceramic though.

Thin tile too🙂

I wouldn’t fix ceramic tiles over ufh, especially British ceramic tile. The layers you have said sound ok if that’s what they have on site.

I’ve tried reasoning with the interior designer and he’s adamant that is what’s being used, he was even sending me screenshots of bct website saying it’s ok to use with ufh with de coupler.
The job is a good client of his as well.
All the materials been supplied by topps 😵.

Sounds typical!
