Hi folks,
I am learning about STC ratings, and it is hard to find a definitive source for all the partition types. We are using metal studs, ranging in depth from 1 5/8" to 8", and we have 5/8" GWB and (2) layers of 1/2" GWB, and most partitions are with and without acoustic batts. Some have the GWB up to the structure above, and some have it to just above the ceiling.
Do you have "official" tables that show all / most of these permutations?
