material for covering Roxul AFB Mineral Wool

[Kerose]

y'all recommend like some burlap or something, or can i just get some felt or anyother fabric at walmart, i am making some panels and am not sure about the safety i should consider

[Mixteco]

I'd get tha thinnest type of fabric I could get ahold of such as linen...

Are you making basstraps or broadband absorbers?

[witzendoz]

If you can blow through the cloth that's a good indicator that the sound (hi freq.) will go through it. If the cloth is too reflective (thick or tight weave) the hi freq. will not get through and not be absorbed by the wool. Mid and bass will go through the cloth regardless.

Cheers
