Hi - some advice would be appreciated.
We are doing a refurb and are having water based underfloor heating installed.
The top layer will be 15mm engineered wood (floating).
Our builder has done things in a backward way so I need advice on what is the best solution given the circumstances.
Builder has installed 100mm of foil backed insulation and then 100mm of sand & cement screed. I have 2 options
1) He is proposing to staple 16mm pipes to the screed and pour 25mm of self leveling screed on top of the pipes.
2) install 20mm wundatherm insulation boards, 3mm breathable underlay & then the top layer.
Which is better solution and is 25mm enough for liquid screed.
Ripping up the existing screed is not an option unfortunately.
Any advice would be appreciated
