Double sheetrock + green glue + Membrane
I am going to be using mineral wool, a certainteed membrane, and possibly 2 layers of sheetrock (1/2″ or 5/8″) with green glue between them. Is there going to be any problem with this design in terms of the membrane’s performance? I don’t want moisture problems by using 2 layers of sheetrock + the green glue.
