Then we get to your NRC score. That rating is focused on absorption, so I see it generally during the context of acoustic control in lieu of audio attenuation/blocking. It can be, indeed, popular to utilize mineral wool batts to develop inexpensive acoustic control panels.
We then focused on the rock wool board items, mainly because their greater density would lower the wind-washing worry and their increased stiffness could possibly aid the set up with the furring strips and siding.
Nicely place. The discussion about if the emissions associated with insulation manufacturing are worth it should be framed being a comparison to other insulation kinds, not like a comparison to the straw-gentleman of not working with insulation or utilizing also minimal insulation.

RE audio attenuation, Johns Manville manufactures fiberglass and rock wool batts -- and states "...the primary difference in acoustical efficiency is so nominal that individuals wouldn't be able to distinguish a difference between the two supplies in a wall cavity." See: Be aware, even so, that JM didn't specify whether dense or common fiberglass batts ended up utilized With this comparison, and sound reduction is a great deal more elaborate than simply just which kind of batt you utilize in a very wall.
