What are you trying to achieve and perhaps others can advise a
different
method?

CM.


The electric meter cupboard really mouldy, because it has 2 external
walls
(one is 3'x2', the other 3'x6") that get condensation. Ventilating the
box
more than it already is (loose fitting doors) would bring more air in
there
to be chilled, cuausing it to drop it's load of water. Since there are
lots
of boxes and wires all over in there, I thought it would be easier to
spray
on a layer of foam than to use polystyrene sheets.

How about ventilating it to the outside?

I would have to insulate the remaining 3 faces to avoid getting condensation
on the outside (the living space side) of the cupboard. It would be easier
though, since there are no wires or boxes on these faces.

That's what I was thinking.

I would also have to seal the doors too.

Wouldn't adhesive foam strip would be enough for that?
