Preventing tiles cracking/moving on suspended floor wet ufh - TilersForums.com

[GinaMJ]

Hello, just seeking some much appreciated advice about tiling over a wet ufh system which is being installed in a 31m2 room with a suspended floor. We’ve bought an ufh system which is specifically designed for this kind of retrofit (Nu Heat lo pro max). The ufh will be encased in self-levelling compound so the tiles will essentially be put on top of a hard concrete like layer. Should there a be layer between the tiles (they are porcelain 90x15x1cm tiles) and self-levelling compound to help protect the tiles against any movement that might occur? Thank you
