To these existing caveats, let me add that most good acoustic
insulation is also good thermal insulation and an overheated gap does
not quench properly.

Commonly, in the old days, the gap was enlosed for sound
suppression, especially when high poweres were used.
Sometimes 'in its own room'.
A point to Ponder is that many sorts of foam are Highly
Flammable. (cf the Station Night Club fire.) I'd be
real careful, in picking. Perhaps 'fiberglass insulation'?
