10m x 6m UFH floor

[Element]

Hi guys,

Laying 600x600 porcelain tiles on a large 10m x 6m screeded, SLC levelled floor with water UFH beneath.. I have laid tiles to plenty of UFH floors before but this one has the longest length run so far - a run of 10m. The question I have in the back of my mind is whether or not it is advisable to put in an expansion joint around halfway across the floor - or is 10m ok?
Cheers for your input!

Put in a soft joint about half way along

Thanks, that's what I thought...

A soft joint should be 6mm , so if you are using 3mm joints put in 2 x 3mm soft joints .
