Question About "hanging" Rockwool between studs

[Audionaut]

Hi guys,
Quick question about fastening insulation. It's been relatively simple for me to affix "rigid" type (702, IB board, etc) to the ceiling and inside walls using Insulation hangers: here's a link below to demonstrate what I've been using (perforated pin hangers):

My concern is with attaching roxul rockwool as it is much more dense, limp and tends to break apart under its own weight...
What kind of adhesives, brackets etc are you using to adhere rockwool to ceilings, floated floors and walls where the design calls for "open" or unsealed cavities, layered back to back.
My wall & floor design is basically SAE's at this link:

-see how the insulation is just floating in the cavities below the plywood floors...
I don't know how I missed the boat on this with all of my books and forums, but is there a trick?
Thanks!
Very Happy

This are industrial fasteners which work for almost ANY type of fiberglass AND rockwool.

I don't say there aren't other solutions as well, but what you show/link is used with thousands for industrial thermal insulation.
These big washers clamp that isolation.
