I am trying to build some acoustic panels for cheepish and have found that the most expensive part is the fabric. I am building 12 2x4 foot acoustic panels (4 to 6 inches thick) with Knauf insulation. And at that scale the GoM fabric is over 500 to cover it. I am looking for recommendations for a cheeper fabric that will look almost as good and keep the insulation in. The Isolation and fabric is linked below. Also if you recommend a different insolation that will do a better job of broad band absorption i am open to that to.

I have look at burlap but i was told the fibers can go right through it. Also if it help any i am looking for a black fabric.
Go to a local fabric store and buy whatever they have that’s the color you’re after. I suspect there will be something that will work wonderfully.
The fabric is there mainly to hold the rock wool/fiberglass into the frame, as long as you don't use something like nylon sailcloth, (with a tight, fine weave and made to hold air…) whatever you find is going to do the job perfectly.

The only thing that appeals to me about the GOM fabric is that it is fire rated AFAIK.
Otherwise use anything open weave.

Rockwool is cheap, and Duvetyn or commando cloth is farly cheap. I haven't used it specifically for absorbers, but I would expect the lighter weights would work well for it and it has a fire rating.
