Stuffing mineral wool in tight puts pressure on the ceiling, and over
a fair area it adds up to quite a lot of force. I wouldnt. As long as
there isnt a damp problem there I'd be more inclined to go with
papercrete, its denser, has a finer porous structure, and stiffens and
damps anything its in conctact with.

Mineral wool has f-all effect on sound transmission. Once you've got rid
of direct air borne paths you need to add mass. Plasterboard etc is
probably the easiest/cheapest way.


Yes agreed on that one, having lived in a terrace house for some years.
The OP or his lady rather will have to accept that sound does travel if
your connected to the gaff next door. A detached house solves this and
its been bliss since I moved into one some 15 years ago now and with
very pleasant neighbours who really couldn't be better...
