Thanks Dmun.

Quality beats quantity most days, eh.

So all, (bar the enclosing dome), is done. Ended up with 75% of surface area having 2" blanket coverage. (Bought a 7600 roll [what's that? 25' maybe? ]of 1"; put on a layer of loose vermiculite to fill the gaps. Vermiculite 'tiles' over that, more loose fill, cover it all with foil, and lay on a light scratch coat of "stuff"* to hold it all in place and provide a key for the final shell.
Warm (min 22 celcius) and raining here at present -perfect curing weather for concrete.
Tomorrow or the next day should see the last of the functional bits done 'n dusted; then the aesthetics: yuk! I lack imagination, please help.
