I didn't use OC 703 or 705 fiberglass... I used minwool insulation by roxul.Anyone concerned about some of that OC 703 or 705 material/fibers being so exposed to you or others? I mean it's not sealed to prevent any particals from drifting in the air that people breath.
Myself, I don't know the exact composition of that stuff but a self proclaimed professional about flipped out when I mentioned I was planning on using that for acoustic panels.
