Just after some advice on insulating and damp proofing an existing concrete floor and putting a wet underfloor heating system down.
Even though we're rebuilding a large proportion of the bungalow and putting on a new roof (forming a 1.5 storey property), due to planning reasons I can't lose too much height in the rooms. Doors etc are not a problem as only a couple will remain and there are currently no stairs. The rooms are currently 235cm high so was planning on around 100mm for the new floor height, give or take.
I was planning on laying a damp proof membrane across all floors and then laying some Celotex PIR insulation on top - about 50-60mm. I was then planning to fix the underfloor heating (wet piped) straight onto the insulation boards, and then screed over the whole lot - approx 40-50mm of screed. On top of this will be engineered wooden floors and tiles (either large ceramic or porcelin). Does this sound sufficient / correct or should I be considering an alternative approach.
Cheers,
