Looking at @NSS blog http://strawberrytreelodge.blogspot.co.uk/2015/09/stage-3-jetfloor-topsheet-ufh-pipework.html , we have the same floor build up but are currently aiming to board out the Jetfloor and leave putting in the final insulation layer and ufh after the frame has gone up. This to to avoid damaging the ufh during erection of the timber frame. Would this be better than putting in the insulation & ufh now?

Jetfloor is now mostly in - the final insulation will go in later. The tricky part was the positioning of the large (420kg - we have a span of 5.5m) ground beams. We hired a 17m telehandler for the day, but lining it up so it was central to the building was a problem. It also tended to nip the dpc in places, resulting in lots of to-ing and fro-ing. The insulation thickness will vary between 80mm above the beams to 230mm between them. With a P/A (perimeter to area) ratio of 0.46, this results in an overall U value of 0.15.
