Hi, I am planning on having my concrete slab insulated with 10mm pir board and also electric underfloor heating, was just wondering how much height it will add to the floor with 8mm thickness tiles. thanks in advance
Hmmm, I'm guessing that would be 18mm then, but don't have mi calculator with me at the moment so not sure. Just add 4mm for leveling & adhesive + thickness of wires.
