Have you seen what a bucket of Green Glue costs? $330 roughly. If it's only 1 wall, it's much cheaper and way less labor intensive to use Quietrock. You fill the back wall with Roxul insulation and then just a single layer of Quietrock. Quietrock suggests not using the channel because of its weight. Make sure no air can get through either so sealing all outlet boxes and such are necessary.
Green Glue and Wall Channel
Have you used the GreenGlue system in your music room? I am designing a dedicated music room for my new house and the back wall of the room will share the wall with our family room. I want to reduce sound transmission as much as possible between the two rooms.
I like the looks of the GreenGlue system that uses two 5/8" layers of sheetrock separated by green glue, hung on their noise proofing clips on metal channel with a 8" wall built with staggered wall studs.
Have you tried the GreenGlue products? How did you like the results? While I want to reduce sound transmission between the shared wall as much as possible I do not want to mess up the sound of my dedicated listening room.
