Fast and easy to use; one of the most effective soundproofing methods is constrained layer damping (CLD). CLD reduces the transmission of sound through a wall, ceiling or floor when used between two sheets of plasterboard, MDF or similar building material.
Soundproofing and technical details
For low frequency sources like subwoofers and footfall “thud”, it is common that more than 80% of the sound energy is generated at frequencies below 100Hz. Most suppliers of soundproofing products use Rw to describe the performance of their products. However, because Rw is for sound above 100Hz, we suggest you don't rely on it. The only reliable way to compare the soundproofing performance of different products is to compare results from certified tests that show the acoustic performance at low frequencies; i.e. well below 100Hz.
Tests, certified to Australian Standards* by CSIRO, show that using Green Glue Noiseproofing Compound between two layers of plasterboard can result in noise reduction equivalent to using four layers of plasterboard. Tests, also show that, unlike competitive soundproofing products, Green Glue Noiseproofing Compound is particularly effective at reducing the transmission of low frequency sound commonly produced by home entertainment, theater systems, music etc.
* Australian Standards for Acoustic Performance: AS 1191-2002, AS 1276-1979, AS/NZS ISO 717.1:2004
At about $20AUD per square metre Green Glue Noiseproofing Compound represents excellent value for your money. It is suitable for soundproofing both residential and commercial projects and is just as easy to use in new construction as it is in modifying existing rooms or renovating.
Green Glue Noiseproofing Compound is low VOC, has almost no odor, does not contribute to mold growth, can be easily cleaned up with soap and water, and has been certified under the Australian Standard for Fire Hazard AS 1530.4-2005 not to alter the fire rating of the walls or ceilings it is used in.
Estimating Quantities: One box (12 tubes) will treat approximately 18 square metres.
Quick and easy to use
Fast – Quickly applied with no measuring or troweling needed
Easy – Simple to dispense with no specific application pattern necessary
Versatile – For use in new construction, remodels, and retrofits
Used by builders, contractors, architects, and DIYers
Multi-Purpose – For use in walls, ceilings, and floors in a variety of applications
Safe – Independently tested by Underwriters Laboratories for fire safety and environmental impact
Effective – Validated by third-party laboratory testing
Must be used between two rigid layers; one layer must be porous; e.g. drywall, plywood, OSB.
Not a sealant or adhesive, therefore fasteners are necessary.
Intended for interior use only. Maintain temperature of 60⁰F - 80⁰F within building after installation.
Not to be used in conjunction with a construction adhesive.
Product intended to reduce sound transmission between rooms, not to affect noise within a room.
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”
