The Double Stud Wall with Green Glue is our highest performing wall assembly. Currently, most acoustical labs have a hard time plotting double-wall performance accurately, as the wall often exceeds the flanking limits of the lab.
A drawback of this solution is space efficiency. With it, you are basically building two walls, which requires a significant amount of space.
