Quartz tiles and underfloor heating - Tile Advice

[Jack123]

Hi.
hope someone can advise on this matter once and for all.
I've recently built a fair size kitchen extension. Block and beam floor with concrete block in fills .
It's kingspanned and will have a 65mm screed on top of a wet underfloor heating system .
approx 6m x6m.
We've been considering the black quartz tiles for the floor 600x600.(sparkly effect)
The problem now is whilst looking around different local retailers I've received very conflicting info.
The tile retailer I use and trust said I should steer clear of these tiles with underfloor heating because of tile cupping or bending due to the resin in the tile.
Now I'm confused ....
Only yesterday 2 big retailers said the tiles would be fine if laid properly over a underfloor heating system.
claiming there quartz tiles were 97% quartz .
Both these retailers said they had never heard of their tiles bending ....
anybody on here actually fitted these and with a underfloor heating system and had no problems??
Thanks

The only quartz tile I trust with heated screeds etc is Gulfstone .

Also seen as you require star galaxy black , then consider star galaxy granite tiles , then 100% no curling issues .

Thanks.
been out today and another different supplier agreed that it's not worth putting down a resin tile if there's even the remotest chance of it curling,
looks like a granite will be the way forward.
i can't help but think these resin tiles look great now but with all plastics they will fade and scratch after time .jack

97% quartz is garbage I'm afraid. If it's "sparkly" more than 3% of it is glass/mirror chips.

Had a great customer once! Bathroom floor in this tile and a piece of glass was missing!!
She wanted me to remove the tile as it was faulty!!!
Bathroom co. had to fight to get paid and as this was before the real knowledge of this type of tile was known - I hope they all came up!!!!
what goes round comes round.

Your welcome - but what adhesive did you use as too much water makes them curl .

 

[Dumbo]

Single part flexible (c2ft) can't remember who's make I was using at that time . No curling . They were from tile giant.
