I've a largish hatch with the ladder mounted on it. It's 1100x700mm, so a
good source of overhead cooling :-( it's this one more or less:

Now, I can't afford to lose any depth behind the treads - in fact, could do
with more - as me feets too big, so the simple method of sticking on 50mm of
insulation is out.

The only other way I can think of is to insulate the underside, but that
means a lump sticking down from the ceiling!

Any ideas, please?
