Hi....I'm not a tiler by trade but have laid a lot of tile in my life. I am now looking at my first UFH job (my bathroom). Laying heating mats on top of concrete floor but don't have a lot of height to play with....porcelain tiles on top. 6mm insulation board is just a bit to thick I think....i'm also in south of spain and a lot of these products are hard to find. I spoke w/ tech help at Warmup USA and they suggested cork with a skim of tile adhesive on top.....i can buy rolls of 2mm cork locally. While I know 2mm isn't much I imagine it is far better than nothing. Does this sound like a reasonable solution or does anyone have any better ideas? I'd probably fix the cork to the ground with some sort of heat resistant adhesive. Also wondering about the adhesive....here we have a product they call Cement Cola which you buy in 25kg bags....and a special one for porcelain which i was planning on using.....most people call for flexible adhesive and this stuff seems quite hard....will this stuff work?? Anyone know of a better alternative in this part of the world?
Many thanks in advance.....

There is an Elektra distributor in Spain who could probably help you. The main man is Dutch and speaks perfect english (and other languages). If you'd like his contact details let me know and I'll get them to you.

Warm Regards,

I think you`ll find even 6mm is near to useless. I wouldn`t bother with less than 30mm of something like celotex or Kingspan/Isotherm etc. Would be interested in what U-Heat advised?

You could not put ufh cables directly onto Kingspan type insulation as it is too soft and the cable would end up embedding into the insulation and then overheating.

I would suggest the use of Thermopanel, PCS or Ecoboard. Yes, 6mm does not have the same insulation level as 10,20 or 30mm but if height is an issue 6mm is better than nothing.

:thumbsup:
