Under-floor heating

The insulation for the floors is all in now and, as luck would have it, you can see all the bits in this one picture:

There's shuttering round the outer walls for when they pour in the concrete and inside comes one layer of black polythene (held together with double-sided tape - but really sticky stuff), then 3 layers of those foam sheets. Next comes another layer of polythene and then steel frames to form the base of the concrete. It's taken 2 days to get all this done and the insulation now fills the space.

If the rest of the heating turns out to be underwhelming we will at least have VERY warm toes!
