I’m considering a vinyl floorcovering for my kitchen – can I still use UFH? 

Yes – although you will need a 6mm self-levelling screed on top of the UFH system before the vinyl is laid.

The reason for this is simple: An inherent characteristic of vinyl floorcovering is that it will soften slightly when heated. This, through time will show the shape of the mats through the floorcovering (commonly referred to as “ghosting”) and the only effective way to overcome this is to use a 6mm screed prior to the vinyl being laid.
