I'm sizing up some of the local screeding firms to see if they have any solutions for fitting insulation and wet UFH in 45mm. I've dug up the the existing tiles and screed and left with only that much depth to play with. Initially I expected that some of the concrete floor could be skimmed, scored, cut out though the feedback so far is that they use "SFUF". To me, insulation needs to trap air and stop it moving heat about, so thicker is better. However this SFUF stuff, at only 6mm deep he claims to be eqivalent to 25mm of celotex. I don't know if they can simply stack it up, 3 layers to give the equivalent of 75mm? I always think if something seems too good to be true, there's a good reason for the unease.

Who has experience with this stuff installed in their home or for their clients? UFH isn't going to be the only heat source in the room - it just seem daft to not fit the coils now I have the screed dug up (I already have a manifold in service with spare ports)
