Depending on how big the bits are, you could "embed" them
in canned foam.

But then if any water gets down there from roof leaks or plumbing leaks
it would stay there and rot the timbers, but with rockwool and loose
fill there'd be telltale black mould on the ceiling below.

I am experiemnting with vertical lines of plasterboard between the
kingspan so any leaks will soak through and show up before rotting the
timbers!¬
