Green Glue -vs- Construction Adhesive
One frequent and rational asked question about Green Glue is: “Does Green Glue outperform Conventional Construction Adhesive commonly found at construction stores."
Test Description - Construction Adhesive -vs- Green Glue Assembly
To address this question, The Green Glue Company ran a series of tests at Orfield Laboratories, a NVLAP certified independent lab in Minneapolis, MN. Below are the wall configurations, from source room to receive room. All details of the walls were identical, including insulation, screw length and spacing, stud configurations, and so forth.

The Effect of Green Glue
Summary of Performance
The rigidity and low damping of conventional adhesives works to worsen sound isolation by lowering the coincidence dip and raising low frequency resonances. Green Glue has a positive effect on sound isolation, making the performance difference between Green Glue and conventional adhesives considerable.
