I know that I saw some somewhere. They were for this place that made cnc cut metal frames. You put the frame together, then you stuff the insulation (OC703 or whatever) into this fabric "sock" and then you put that into the frame which was snug enough to hold everything in place. Let me see if I can find it.

At out church they have massive "cloud" panels hanging from the ceiling and huge panels on all of the side walls and the back wall. It would take a good number of 2x4 panels to put a big dent into it, but it would be worth trying.
