Hello, I'm looking to purchase some high density eco friendly acoustic materials for building panels such as cotton or polyester materials. I don't want to use rockwool or fibreglass because of the air quality and safety hazards these materials contribute to. I live in Toronto, Ontario, Canada and I'd like to order within the country or ideally purchase from a local supplier.

Kurt,

There are several errors in your assessment of acoustic products. [Is there a reason you keep opening and closing that thread?]
