Thanks for all the replies, guess I'll give up on the rockwool idea
but it still needs lining out as it's not that easy to fix shelves to
a single metal skin.
Thinking that a green roof might be a reasonably cheap option with
climbers like ivy up the exposed sides. But that still leaves the
doors that face due south and soak up masses of heat.
I think interior insulation is the only way. Ask anyone who's spent time
in a caravan during extreme weather :-)
How about using exterior insulation products such as done to the outside
of houses?

Insulation needs to be exterior really. If its interior you'll get
interstitial condensation, the metal will rust badly, the insualtion
will saturate and conduct, and evil moulds will flourish. Unless you
laeve a gap from the metal and drill vent/drain holes.

Rockwool holds water, but polystyrene doesn't. The container walls may
be ribbed, which would provide ready made gaps behind the
battens/insulation. Any condensation would then drain down to the inside
floor, where at least you could see what you're dealing with.

I've certainly had saturated polystyrene, but it wasnt being used as
wall insulation.


Quite agree about the passion flower. It would cover the whole thing in
a couple of months, but would need to be south facing, and have a
structure (just string will do) to climb up. They don't have suckers
like other climbers. A bit of a mess in winter though if mine is
anything to go by.

true - very rustic. OTOH the fruits hang on the vine for months
looking nice.
