The best room upgrade: $2250

Florida sounds like *ell! Why would anyone want to live there? 

I have 17” of rock wool in the ceiling, 6” in the walls. For thermal performance reasons mainly, but my architect said to cover with fire resistant burlap instead of sheetrock and I would have a recording studio quality sound to my room. He was not wrong.

I am not a fan of blown in insulation. The off-gassing fumes are terrible. It’s a petrochemical product that’s bad for the environment. 

@tweak1 now all you need is to add impact windows and you will get an insurance reduction along with further noise reduction. You won’t even hear the hurricane outside,

Get 6 Stillpoint Apture panels ASAP!!

Relevance to OP? (LOL.)

And so the silicone is on the outside of the roof. I certainly can see the thermal and acoustic advantages of incoming heat and sound. That certainly makes a huge difference but I don't think it makes much difference in the inside acoustics in general. You still have the same reflective surfaces albeit a more dampened planar surface which is what would make some difference but it would be interesting to measure before and after. I just finished a new room with a vaulted drywalled ceiling. Shingled roof, 2 x 12 rafters filled with R38 fiberglass batts.
I know it's going to be an issue so once we get the area rug in (concrete floor East Texas), the furniture and the system back up, we will deal with it then. Probably panels on the ceiling of some type.
