Tim Duffy from Simply Home Entertainment told me he used a product from recycled denim (a "green" product) for TV producer, Phil Rosenthal's new theater. That is something you could look into.
I used "spun glass" behind my RPG BAD pannels and in front of my fabric wall. That was a pretty effective solution that is also pretty cheap.
