Athletic wear vs Speaker Fabric. Help!

Hello,

I am building some acoustic panels using Roxul (mineral wool). I am going to buy fabric to cover them and today I was at the fabric store. The girl showed me speaker fabric but when doing the blow test I didn't think it allows a lot of air through. She also showed me Athletic wear and that actually allows way more air when you blow. My only concern is that having little holes (athletic wear does of course) may not be good because with time fibers from the insulation materials will pass through. As you imagine I spend most of my life in the recording/mixing room so I am worried about the health hazards of this. The question is: Do you know about Roxul use in long term? and also should choose Speaker fabric instead? Athletic wear is not only cheaper but allows more air. Any insights are appreciated. Thanks.

I'm far from an expert on this, but why the concern about the fabric being able to have air "pass through"? IIRC, most of the baffles and gobos I've seen used either muslin fabric or burlap.

Then you would want a material with a dense enough weave to prohibit the Roxul fibers from escaping. I would think a fine weave muslin would work. And if you want it absolutely air tight, some sort of plastic 1st, then cover with a fabric.

It's not that big of a concern. It isn't going to spontaneously start flying around.

I covered mine in dyed burlap.

Spend a little more and order proper coverings for your acoustic panels. I ordered mine from gik acoustics but there are some sellers on ebay offering the same materials as factory seconds for less money. They are fire resistant, look awesome, easier to install and hold their tightness long term much better than cheap fabric store materials.
