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.
