The condensation I had in a self storage place was, I think,
exceptional.  And of course unlike a loft it didn't have any air
circulation.  But have seen a few drips of water on the inside of my
roof which I believe to be condensation.

When my flat was built 20 years ago the builders must have used the
very cheapest loft insulation.  It seems to be very tiny bits of
paper.  Much of the insulation is like dust!  Have to wear a mask if
I'm up there for long.  But as the original poster has foam
insulation, he shouldn't have too much dust.

Difficult to blow out the dust in a UPS!  Have to disconnect
batteries as well as unplug from mains.  Then should discharge
capacitors before dusting out.
