I'm planning to install underfloor heating in adjoining kitchen and front room. approx 17m2 @ 200w each. the subfloor is caber floor well screwed down onto new joists. can i lay 6mm xps insulation screwed down, primed, underfloor heating mat then screeded with nx self leveller. im planning to split into 2 screeds with expansion perimeter and field and install expansion joint at point of tiling. can anyone see potential issued here. any advice would be greatly appreciated!
