Organic Acoustic Insulation?

I remember a thread years ago, that was talking about toxic stuff in rockwool or glass fibre and then some one on here dangled a home tester kit in the middle of his studio to test for said chemicals and the results were low or w/e

Can't find the thread..

But the question is, is there any organic none toxic treatment for bass traps/insulation like rockwool etc?

If anyone can remember the thread please link me to it..

the stuff you are thinking of is probably formaldehyde. Polyester batts don't have any. Also, Knauf makes formaldehyde-free Glasswool insulation batts. There are also batts available made from cotton fibres but these fibres can have their own issues. In Europe there is also a hemp fibre insulation batt product (industrial hemp, no THC).

Depends on what "Organic" means. Rockwool is made from basalt rock rather than glass, so its natural, but they still use glues to hold the fibers together. The only true formaldehyde/phenol chemical free product is the Knauf Ecose to my knowledge (or atleast promoted that way). There are also non-bound products such as cellulose or denim, but those usually have chemicals to make them fire-rated and or mold resistant.
