Overview
The Green Glue Company Case of Green Glue Noiseproofing Compound 12 Tubes is a viscoelastic polymer designed for construction, renovation, and soundproofing applications. Sold in cases of 12 tubes, each tube contains 29 ounces of compound. The product is formulated to be applied between layers of building materials such as drywall to reduce sound transfer. It is used by adding an additional layer of material over an existing wall, floor, or ceiling structure.
This case of 12 noiseproofing compound tubes includes installation instructions in English and Spanish along with data sheets. The material is dispensed using a standard large-size caulk gun and applied in a random pattern to the surface before the second layer is installed.
Material and Application
This solution consists of a viscoelastic polymer that remains workable during application. It is intended to be applied between rigid construction materials to damp vibrations that contribute to airborne and impact noise transmission. The compound is designed for use on walls, ceilings, and floors by installing it between two layers of drywall or similar building panels.
Application involves dispensing approximately two tubes per standard 4-foot by 8-foot drywall sheet. The compound is described as flowing easily from the tube, and installation requires a large caulk gun rather than a smaller bathroom-style applicator. After application, the second layer of drywall is secured in place over the compound.
In documented test configurations, a standard single stud wall with common drywall achieved an STC rating of 56 when the compound was used between layers. Low-frequency sound isolation was reported as improved over older techniques, and the material is identified as one of the few products that reduces both impact and airborne noise when used as part of a layered assembly.
Performance Characteristics
The compound is described as offering up to 90% noise reduction, particularly for low-frequency noises. Independent laboratory testing has been referenced in the product description. In practical installations described in reviews, users commonly report noticeable reductions in noise transmission when the compound is used between multiple drywall layers and combined with insulation and decoupling methods.
Users frequently note that the material cures slowly and can remain tacky for an extended period after application. Full effectiveness is typically associated with the curing period. The compound has a mild odor and can be cleaned with water before it dries. These characteristics are consistent across repeated review summaries.
When installed as part of a multi-layer assembly, including additional drywall mass and sound isolation clips, reports commonly describe significant reductions in conversational noise, music, and other airborne sound transmission. Impact noise reduction is also mentioned when combined with added mass and isolation components.
For those evaluating a viscoelastic sound damping compound for layered drywall systems, this material is designed specifically for installation between rigid building surfaces.
Installation Context
This compound is intended to be part of a broader noise-reduction system rather than a standalone surface treatment. Reviews frequently describe installations that include 5/8-inch drywall layers, insulation, and sound isolation clips or channels. The compound is applied between drywall sheets, typically using two tubes per panel.
Electrical outlet extensions, acoustic sealant around seams, and careful sealing of gaps are commonly mentioned as complementary installation steps. The material is used on walls and ceilings in residential environments, including bedrooms, multi-family buildings, and shared-wall applications.
As part of a layered approach, the compound is positioned between structural surfaces where vibration damping is required. This approach aligns with the intended use for construction and renovation projects focused on reducing sound transfer.
Installers looking at a drywall damping compound for noise reduction typically integrate it within assemblies that add mass and mechanical decoupling.
