Thanks Nick. I hadn't thought about making the frame deep enough to include the air gap -- that's a great idea and takes care of the inevitable "gee why are your pictures sticking out from the wall ?" questions. Thanks !

I was eyeing another Roxul product at HD called ComfortBoard, probably more like OC 705 I guess ? 1.5" thick and definitely denser / more rigid than the Safe 'n Sound.

The room is feeling just a tiny bit too dead, although I'll let it "break in" for a while before I decide laugh

Guess after all these years I'll finally have to find out what muslin is. And go in a fabric store. Yikes.

EDIT - OK, so Wikipedia says :

1. Not to be confused with Muslim (knew that)

2. A cotton fabric of plain weave (didn't know that)
