RockWool Questions, Types

[ecsmix]

Hi guys I would like to use the rockwool to help me with the reflections.

The guys from the manufacturer told me that the hard panel is best usable between two walls.Because it may looses some of it pieces on the air and I will breathe that.

So I was wondering about those other products:

these other products are mineral wool, rock wool, fiberglas. the FSR looks to be about right in terms of minimum density but without tests on its acoustic properties, your better off with known products. cover them in cloth or add a layer of light plastic if you're concerned about the fibers. there are also recycled cotton and hemp products but they are generally more costly but don't have the irritating fibers (although you have to check closely on fire retardants used and chemicals used to process...)
