acoustic treatment/panels

Hello, I'm getting ready to build some acoustic panels that I plan to hang from the walls in the control room to help with reflection... My design includes buildings frames, wrapping the frames with fabric and stuffing the back with some kind of acoustic treatment. I was thinking about using mineral wool and sealing it in plastic to keep the dust under control. Does anyone have any experience with this, or have any other suggestions? Thank You:) andrew
