Re: Another "stealth" idea

Yes, rigid fibreglass would work also. Compared to the batting material I mentioned in the same location, the fibreglass would absorb at lower frequencies and reflect at higher.

My main concern with fibreglass is the health issues. I used to work in occupational health and safety so I do tend to consider those things. You would need to wrap the rigid fibreglass to reduce the possibility of fibre shedding and, if you use batting materials for that as Jon Risch suggests in several places in his acoustics pages, that will give you the benefit of some absorption at higher frequencies where the unwrapped fibreglass would reflect.

Spacing the paintings away from the wall by a couple of inches will help also if you can find a way of doing that. Putting wooden spacers behind the corners of the frames would do the trick.
