[Cob] Soundproofing on a traditionally built wall

[Elizabeth]

Wouldn't this replace the "built-to-code" non-flammable insulation with something not-to-code and flammable?  Might not be a good idea in a building occupied by other owners.  Even tightly packed straw bricks will burn much faster and hotter and fiberglass insulation.
 
I would make the same point re the idea of using wax-soaked burlap to cover drafty gaps between rafters, mentioned in another thread.  This sounds like an extremely flammable material.
 
My sister once lived in a stone dormitory at  a women's college--the shell of the building was stone, but all the interior walls were insulated with 1920s newspapers.  The fire department estimated the building had a fire life of (if I remember correctly) 30 seconds.  That is, once a single room was completely involved in flames, the fire would flash through the newspaper stuffed walls and engulf the entire building in 30 seconds.  They took fire drills very seriously.  A girl who chose to sleep in the buff would be expected to run naked down the stairs and onto the lawn at 2 a.m. My sister decided PJs were a good idea.
