Is fiberglass insulation available in 19.2" widths?

My TGI floor joists are spaced 19.2" (5 per 8ft)

I want to insulate the ceiling for sound isolation.
I haven't been able to find insulation for this width other
than buying 24" width and trimming it down.
Not cost-effective, and more work.

Is it possible to purchase 19.2" wide rolls of fiberglass
insulation? Where?

Have you thought about using blown-in-insulation?

I've checked Owens Cornings product catalog and find nothing they
manufacture to meet your needs ( all for 16" or 24" cavity )
I would recommend you make them aware of your special need directly.
We have a link through our website, or go direct at
http://www.owenscorning.com Hope this helps.
I would expect cutting down 24" width insulation will be your only
timely option. Hope this helps.

Would the amount of compression required to install 22 1/4 width insulation
really make that much difference? If the cavity depth is not completely
filled, chances are the insulation could be placed in a uniform shape
thereby distributing the compression over the entire width. Since your only
requirement is sound reduction, maybe there are better alternative
solutions, resilient channels for example.

Mmmmmmm. That's a tough one. I've seen 19.17" but never 19.2"

This is not my area of expertise, but I have had better results in reducing
sound transmission by doubling up drywall layers than I have by insulating.
