Overview
Green Glue Company Case of Green Glue Noiseproofing Compound uses a viscoelastic polymer between rigid construction panels. Also, it targets airborne and impact noise in walls, floors, and ceilings.
The compound is designed to reduce sound transfer when sandwiched between layers of building material. It supports construction, renovation, and soundproofing work across residential and light commercial settings. The material functions as one damping layer within a broader sound-reducing assembly.
Key takeaways
- The case contains twelve 29-ounce tubes and weighs 27.2 pounds.
- The compound converts sound energy into heat through internal damping between rigid panels.
- Typical coverage uses about two tubes per 4-foot by 8-foot drywall sheet.
- Application can increase to about three tubes per sheet for additional damping.
- Independent laboratory testing reports STC 56 in a standard single-stud wall assembly with common drywall.
What the product is designed to do
This viscoelastic soundproofing compound reduces sound transmission through layered walls, floors, and ceilings. Also, it addresses both airborne noise and impact noise within suitable construction assemblies.
Airborne noise travels through the air before reaching a partition. Impact noise begins with direct contact, such as movement across a floor. The compound supports both noise types by adding damping between rigid layers.
Common settings include bedrooms, offices, hotels, multi-family housing, home theaters, and recording studios. In addition, it supports wood or tile floor assemblies where impact and airborne noise control are part of the design.
Materials, dimensions, and technical details
| Detail | Specification |
|---|---|
| Material | Viscoelastic polymer |
| Package quantity | Twelve tubes |
| Tube size | 29 ounces |
| Case weight | 27.2 pounds |
| Typical coverage | About two tubes per 4-foot by 8-foot drywall sheet |
| Higher application amount | About three tubes per sheet for additional damping |
| Application tool | Compatible large-size caulk gun |
The material uses internal damping to convert sound energy into heat between rigid panels. Also, the relatively fluid consistency supports quick dispensing from a large caulk gun.
The case includes installation instructions in English and Spanish. In addition, technical data sheets come with the twelve-tube package.
Installation and placement notes
Apply the compound in a random bead pattern across the backside of drywall before fastening the next layer. Also, place it between rigid construction panels rather than on an exposed finished surface.
Existing walls, floors, or ceilings can receive another material layer with compound between the layers. For more application context, this guide to using Green Glue in soundproofing work covers the same layered construction context.
Common assemblies use multiple layers of 5/8-inch drywall with insulation, decoupling clips, and hat channels. Next, plan for panel lifting, secure fastening, and electrical outlet extensions when added drywall increases wall thickness.
Gap sealing with compatible acoustic sealant also appears in layered sound-control projects. However, the compound itself functions as a damping layer between panels.
Performance characteristics described
Independent laboratory testing reports an STC rating of 56 in a standard single-stud wall assembly with common drywall. Also, low-frequency sound isolation was greatly improved compared with older techniques.
STC refers to a wall assembly’s airborne sound transmission performance. The reported result applies to the tested assembly, not the compound by itself.
The 12-tube damping compound case supports broader systems using mass, insulation, clips, channels, and layered drywall. As a result, its role centers on damping movement between rigid panels.
The compound cures slowly and may remain tacky for an extended period before reaching full performance. However, the relatively fluid consistency supports random-pattern application across drywall sheets.
Review patterns buyers commonly mention
Recurring installation patterns include use between multiple layers of 5/8-inch drywall. Also, broader assemblies commonly combine the compound with insulation, decoupling clips, and hat channels.
Planning often includes added drywall, electrical outlet extensions, panel lifting, and secure fastening. In addition, slow curing and an extended tacky period recur as practical installation characteristics.
Pros
- Targets both airborne and impact noise within layered assemblies.
- Supports walls, floors, ceilings, and existing construction surfaces.
- Uses a standard large-size caulk gun for random-pattern application.
- Includes twelve 29-ounce tubes for multi-panel work.
- Reports STC 56 in a tested single-stud wall assembly.
Cons
- Requires placement between rigid construction panels.
- Slow curing can leave the compound tacky for an extended period.
- Added drywall can require outlet extensions, lifting, and secure fastening.
- Broader sound-control work can involve insulation, clips, channels, and acoustic sealant.
FAQ
How much compound goes on one drywall sheet?
Typical coverage uses about two tubes per standard 4-foot by 8-foot drywall sheet. Also, application can increase to about three tubes for additional damping.
What type of noise does it address?
The compound targets airborne noise and impact noise. In addition, it supports low-frequency sound isolation within layered construction assemblies.
Where does the compound go?
Apply it in a random pattern on the backside of drywall or another rigid panel. Next, fasten the additional layer over the existing assembly.
Does it work as a complete wall system?
It functions as a damping layer within a broader wall or ceiling system. Also, common assemblies use drywall, insulation, decoupling clips, and hat channels.
What equipment does installation require?
Installation uses a compatible large-size caulk gun. The 29-ounce noiseproofing tubes dispense in a random bead pattern across rigid panels.
