Our neighbour told me that, when she had cavity wall insulation

sure whether this was because upstairs was solid or a thinner cavity.

Has anyone come across this type of construction before? Is it more
likely that it's solid or just a thinner cavity? I'd have thought that,
if a cavity existed, it could be filled with the kind of blown
insulation that's used today.

I've never heard of this, but until c.1974 the regs allowed 75mm blocks to
be used for the inner skin of a cavity at first floor level. The cavity
width shouldn't be reduced though.
