Green Glue Soundproofing Compound
Green Glue Noiseproofing Compound is one of the most effective constrained layer damping solutions for reducing sound transmission in walls, ceilings and floors. Especially effective on low-frequency noise, it’s CSIRO tested and provides excellent value for residential and commercial projects
What is Green Glue?
Green Glue is a viscoelastic damping compound that converts vibration energy into heat when sandwiched between two rigid layers of plasterboard or similar materials. This constrained layer damping mechanism helps reduce sound energy passing from one room to another.
Constrained layer damping
Used to reduce sound through walls and ceilings. Excellent at blocking low-frequency noise.

Green Glue vs Soundboard test result
What Green Glue does (and what it doesn’t)
Green Glue helps with:
Reducing sound transmitted between rooms through walls/ceilings/floors
Improving performance for low-frequency sources (subwoofer bass, footfall thud)
New builds, renovations and retrofits
Green Glue does not:
Work as a sealant or adhesive (you still need fasteners)
Replace airtight detailing (gaps/penetrations still matter)
“Fix” echo inside a room (that’s acoustic treatment)
Why low-frequency performance matters
For low frequency sources like subwoofers and footfall “THUD”, it’s common for more than 80% of the sound energy to be generated at frequencies below 100Hz. Many suppliers quote Rw, but Rw is measured for sound above 100Hz, so it can be misleading if your real problem is bass and impact noise.
The most reliable way to compare soundproofing products is to look at certified test results that show performance well below 100Hz.
CSIRO-tested performance in Australia
Lab testing Green Glue at CSIRO
Certified tests by CSIRO to Australian Standards show that using Green Glue Noiseproofing Compound between two layers of plasterboard can provide noise reduction equivalent to using four layers of plasterboard. Tests also show Green Glue is particularly effective at reducing low-frequency transmission compared to competitive products.

Typical applications
Green Glue is commonly used between layers of:
Plasterboard (walls/ceilings)
MDF / plywood / similar rigid sheet goods
Works well for:
Home theatres & media rooms
Studios
Apartments / multi-residential
Commercial fitouts
Applying Green Glue to plasterboard
Installation is
Fast: no mixing, no measuring, no troweling
Easy: dispense from tubes; no special pattern required
Versatile: new construction, remodels, retrofits
Where: walls, ceilings and floors
Important limitations:
Must be used between two rigid layers; one layer must be porous (e.g. drywall, plywood)
Not a sealant/adhesive, fasteners are required
Interior use
Don’t use with construction adhesive
Intended to reduce transmission between rooms, not change sound within a room
Don’t forget airtight, airtight, AIR TIGHT! (sealant matters)
Green Glue Compound treats the structure-borne transmission, but good soundproofing also needs airtight detailing at junctions and penetrations (wall-to-wall, wall-to-ceiling, outlets, etc.).

Testimonial
COMMENTS FROM THE BUILDING MANAGEMENT:
“The results are amazing. Since installing the Green Glue, we have not received a single noise complaint. We are very pleased with the results. We placed a very loud air compressor in a bedroom as a test. This was much louder than a typical condo owner would play music. In the room next door we heard nothing. It was unreal. Our installers found the Green Glue tubes to be extremely fast and easy to work with. We tried other methods of soundproofing such as soundboard and resilient channel. We found Green Glue to be the least expensive and clearly the best performing”
