Product Overview and Intended Use
This compound is identified for construction, renovation, and soundproofing applications. It is supplied in twelve 29-ounce tubes per case, and each case includes installation instructions in English and Spanish along with technical data sheets. The material is described as a viscoelastic polymer and is designed to be dispensed using a standard large-size caulk gun.
Application involves spreading the material in a random pattern between layers of drywall or other construction panels. The manufacturer states that the compound can be used over existing walls, floors, or ceilings by adding another layer of material to reduce sound transmission. Independent laboratory testing referenced in the product description reports an STC rating of 56 when used in a standard single-stud wall assembly with common drywall. Low-frequency sound isolation is described as improved compared to older techniques, and the compound is indicated to reduce both impact and airborne noise.
Material Composition and Technical Characteristics
The compound is categorized as a viscoelastic polymer, which allows it to convert sound energy into heat through internal damping when sandwiched between rigid panels. The product is dispensed from large tubes and applied in a random bead pattern across the backside of drywall sheets prior to installation.
The package weight for a case is listed at 27.2 pounds. Each tube contains 29 ounces of material. Installation requires no specialty equipment beyond a compatible large caulk gun. The product description notes that approximately two tubes are used per standard 4-foot by 8-foot drywall sheet, with the option to increase application to about three tubes per sheet for additional damping.
For detailed specifications and packaging information, the Green Glue Noiseproofing Compound case listing outlines material type, intended uses, and included documentation.
Performance Characteristics
According to the product description, third-party acoustical tests demonstrated an STC rating of 56 when the compound was incorporated into a standard wall assembly. The description also states that low-frequency sound isolation, which is not included in STC testing, was greatly improved compared to older techniques.
The compound is described as one of the products capable of reducing both impact noise and airborne noise within multi-family housing, hotels, offices, home theaters, recording studios, bedrooms, and wood or tile floor assemblies. Application guidance specifies spreading the material in a random pattern to achieve cost-effective coverage and effective damping between layers.
Installations referenced in product information and reviews commonly include use between multiple layers of 5/8-inch drywall, often in combination with insulation, decoupling clips, and hat channel systems to form a complete sound-reducing assembly. While the compound functions as a damping layer, it is typically integrated into broader wall or ceiling systems designed to control sound transmission.
Installation Considerations
The compound is applied directly from the tube onto the backside of drywall sheets. It is noted to dispense quickly and easily due to its relatively fluid consistency. The material cures slowly and may remain tacky for an extended period before reaching full performance.
Installation scenarios described in product content and recurring review themes include adding additional drywall layers to existing assemblies, sealing gaps with compatible acoustic sealant, and coordinating with electrical outlet extensions when increasing wall thickness. The product does not require specialized tools beyond a large caulk gun but does require planning for panel lifting and secure fastening during installation.
For projects involving walls or ceilings where added mass and damping are desired, the 12-tube soundproofing compound case provides sufficient quantity for multi-panel installations in residential or light commercial environments.
