Hello all. I hope all is well. Update: insulation/PIR is in the floor. We were let down by the UFH guys we'd booked. So had to find a more reliable company, who will be coming in on Monday. Frustrating as we'd wanted this in by now to protect the PIR, but alas, we are where we are. Screeding should happen the day after pipes are laid (or very close to it), I am told by the builders, and then that is the floor done!!
