I got some samples from SoundAway, which are cotton that has been treated to be less flammable. The specs are better than many materials, it's not like fiberglass WRT particles being circulated and entering eyes, lungs, etc. I have seen recommendations for Roxul, but have never used it.
Have you looked into using diffusion, rather than eating acoustic energy through absorption? How do you plan to arrange the areas that are treated vs left alone?
I have stacked stone columns in the room for aesthetics and diffusion. The front proscenium will be covered in stone as well. I have treatments arranged the best I could without looking stupid at what should be 1st and 2nd reflection points if my angles are correct. Then absorption along the back wall inset with paneling trimming it out.
I was looking at the roxul, studio pro acoustic foam, I found one called Eco-c-tex that has its performance rating listed being right around that of 703 for less money.
