Quartz and under floor heating

[One Day]

I assumed it escapes over time at the edges. Up the skirt

How does that perform its job if there is insulation boards stuck down first as would be with this job

It probably won't! With 10mm insulation boards, I wouldn't bother with any type of membrane. The boards will bridge cracks.

But what about the expansion and contraction of the ufh ? Does it not need a decoupler directly under the tile ?

35sqm, multiroom? I'd say no.

Cheers, I'll get any more info I can this evening.
