material to hold wall insulation in position?

Hello!
I'm building a room within a room style studio in my garage and am going for a 2 leaf system. The outer leafs are 2 layers of drywall but the interior between the 2 walls is simply the insulation in each wall and the air gap. I'm nervous that the insulation may slip or fall backwards into the cavity and was thinking about putting something along this wall interior to hold the insulation in place. Perhaps a few strips of chicken wire? or some kind of breathable fabric?
I'm assuming that using any kind of cheap plastic sheeting would be bad due to to possible moisture/mold issues. although this is tempting because it's so cheap.

Of course, I'm hoping to use something that is not too expensive... :)

Thanks in advance for any suggestions.

Yeah, some of it may be the rock wool batts. Other areas are the paper faced pink r-13 so that can be stapled. I'm more concerned with the rock wool.

I'm not understanding you properly there. Have you got a photo or sketchup model that you can post up to explain?


all the best,
