Green Glue Compared to Engineered Damping Glue
One frequent and rational asked question about Green Glue is: “Does Green Glue outperform Engineered Damping Glue."
Test Description:
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.
