Hi, I'm in the middle of a sizeable extension / renovation project, and most of our house has standard timber floorboards (30s semi-detached). Builder was going to put wet underfloor heating under the new extension and suggested we do the rest of the ground floor, but he's suggested we put it embedded in some kind of solid Kingspan-type insulation - and lay this on top of the existing floorboards.
I can't find any specific info on this online, and I'm wondering if / when it makes sense? We have airbricks at the front of the house beneath the floorboards so the floors are cold. I was going to put solid insulation underneath the floorboards before we put new flooring on top, but our builder suggests we shouldn't bother as his solution would be more effective.
What do people think? Is this a sensible way to install the heating? It would raise the floor around 30mm he says, which I can live with, but I want it to be effective given that a new set of laminate or whatever will make further changes much harder work later.
