Is there a requirement or prohibition that would not permit exposed flex duct within a living space in a SF dwelling? I see the flame spread requirement for interior finishes and I think this duct is 25 so it would probably pass that. Just not sure if there is anything else. I am limited to IRC, chapters 1-11.
