Thanks alot bri I will give this a read now I've put little man to bed 🙂 thing is I've installed the mats on to screeds before and never laid a board down? I can see why you do and when I lay one onto a timber floors I always put a hardie board onto the ply. Does it vary depending in what brand of mat it is to weather you need to board it? As I said the manual and the rep said straight onto a screed is fine? I'm confused lol

The insulation is a must, otherwise you will be heating 100mm + of concrete as well as trying to heat the floor/room. Very expensive running costs as well.

The awesome tilers forum member was you lol!!! Ok mate what is the minimum thickness of board you can put down as I have very little to play with?

the thicker the better, but even 6mm is better than nowt.

Thanks mate I think on this occasion it will have to be 6mm. But in future I will lay it this way. It has blown my mind a bit though as in the installation guide there is no mention of putting a board down?? Weird

They've probably got a deal with the electric companies, the reps get a cut!

Haha I recon you could be right mate!! Other than the obvious heat loss through the concrete screed will not putting a board down effect any aspect of the actual tiling? As I said I have do e a few and am now worried will the tile/ufh fail without the board?

it won't fail without the board,,,just be damned expensive to run!
Sorry Bri mate. I didn't have time to go look for it. I was debating between the two of you. 😱
The manufacturers installation instruction will more than likely specify the use of an insulation board. The likes of Warm up even tell you the minimum thickness (10mm with them). I don't know where you would stand on warrantys in the event any do fail.
