Sound Batts - Division 07 or 09?

I am averse to specifying sound batts in Division 07 - especially if I don’t have any other insulation.

I am inclined to specify them in 09 8116 - Acoustic Blanket Insulation.

Am I thinking right?

If their only location is in metal stud-framed gypsum board partitions, I specify acoustic batt/blanket insulation in 092900 Gypsum Board.

I used 098116 only if the insulation is used in wood stud-framed partitions.

I have used 098100 Acoustic Insulation mostly for theater or broadcasting projects, where there has been multiple types of acoustic insulation.

Often I’ll include the sound batts in 09 21 16 - Gypsum Wall Assemblies.

I typically use 09 8116 because sound batts are frequently used in multiple applications. This avoids having redundant provisions in several sections (shaftwall, gyp board, etc).

Thanks, everyone, for your perspective on this.
