How does Green Glue outperform a limp mass product?

Well the reason is that simply putting limp mass into an assembly cannot make the entire assembly limp. MLV cannot make drywall less rigid, and it cannot cause the drywall to not conduct vibration, and it cannot damp the resonances in the drywall as it’s hardly in contact with the drywall at all. The wall remains stiff and prone to resonance, but with added weight of the limp mass material and some other benefits. Similarly, adding Green Glue to a wall doesn’t make the wall limp either. Green Glue can’t make drywall or studs less rigid, but the damping behavior of Green Glue can greatly impair the ability of the drywall to conduct vibration one of the marvelous properties of a limp mass. And the damping behavior of Green Glue can notably reduce the resonant behavior of the drywall the second of the great attributes of limp mass materials. Thus, it could reasonably be said that Green Glue goes much farther towards reaching that holy grail of “limp mass” than does the addition of ...  more
