I am hoping you can help me with my underfloor heating problem.
I am currently building an extension to the rear of the property and have now decided after the floor has been prepped and signed off to try and install underfloor heating. Floor construction is MOT, sand blinding, DPM, 100mm insulation and a further layer of dpm. This leaves 100mm to reach DPC. Almost all recommendations by suppliers say that 100mm is too thick of a slab to place underfloor heating in and to reduce this to use a screed,however this means that the floor will not satisfy the required 100mm under regs. I lf I was to screed on top this would raise the floor in comparison to adjoining rooms. Help!
Has anyone any experience of laying UFH in a slab this thick and achieved decent results?
If so what effect does piercing the second layer of DPM have?
Any other suggestions on how I can still achieve UFH in my situation?
Many thanks in advance!!!
