GRFFN GLUF VS. FXTRv HRYWvLL One of the most frequent and rational questions about Green Glue is thisC “SureV Green Glue performs wellV but does it really outperform just adding more layers of drywallB” We will answer that question herein. TFST HFSzRIPTION – zONVFNTIONvL HRYWvLL vSSFMkLY SVS S GRFFN GLUF vSSFMkLY The difference is impressive. Unlike resilient decoupling methods that cause performance to suffer at some part of the low frequency rangeV Green Glue has a sizeable positive effect at low frequencies. PvRT Y – THF v;;FzT O; GRFFN GLUF To address this questionV The Green Glue zompany ran a series of tests at Orfield LaboratoriesV a NVLvP certified independent lab in MinneapolisV MN. kelow are the wall configurationsV from source room to receive room. vll details of the walls were identicalV including insulationV screw length and spacingV stud configurations and so forth. Wall configurationsV from source room to receive room. Official lab reports are availableI the applicable test numbers are given in the chart below. ky testing an identical wall configuration with and without Green Glue it is possible to divine the effect of Green Glue on this type of wall. This graph illustrates the effect of Green Glue as demonstrated by the above tests. It must be noted that the Green glue wall may have been limited by flanking noise in the laboratory over much of the frequency range. The important point of this flanking discussion is that the real benefit ofGreen Glue may be even larger over much of the frequency range if flanking noise was not present. In real world situationsV the level of flanking noise may also affect results.

Cost per square foot per improvement in STCWhen compared to a standard wall with a single layer of drywall on each side.
-Green Glue is notably cost effective in this analysis. Only materials and labor are included, if floor space was accounted for, the margin would be
immense. The flanking limit of the lab may make this comparison somewhat unfavorable to Green Glue, as the STC of the Green Glue assembly may in
fact be higher.
