6mm board is fine........(and has insulation properties v. similar of 10mm!) but level the floor first.....then lay insulation......then level again and tile.......this way you get the most heat transfer.......all the best
Thanks Lee, I have just quoted a job using exactly this method. I doubt I will get it, as someone will come along and say " you don't need to do all that" they will be much cheaper than me, but I know they will be cutting corners. I'm sure my competitors will dot and dab the 600x300 porcelain tiles directly to the concrete, maybe primed with PVA.
I hope my potential client is reading this thread, it may help me win the job.
