Hi, I have a couple question regarding the preparation of the sub-floor for underfloor heating, I hope someone can help me.
I will be having UFH installed in my kitchen, it is a suspended timber floor, the finished surface is to be tiled.
I intend to prepare the floor myself, the plan being to remove the existing floor boards (to reduce the final overall build-up) and screw 18mm ply directly to the joists, with a further 10mm on top, running in the other direction, staggering joints as suggested by the BS.
1)
Will this provide a stiff enough base (considering I have removed the original floor boards) for my tiling? Or do I need a thicker ply build-up?
2)
What build up is required above the ply, ie screed or insulation mats?
I expect the answer my depend on whether I am having electric or hot water - Ideally I would like hot water as I have heard it is a 'more even heat' any advice on this and how it would effect the base required would also be much appreciated.
Thanks in advance for your help.
