Green glue

Has anyone actually used green glue themselves and what was your impression building theatre room looking at greenglue over std 10 mm board then adding 13 sound check board is it worth the trouble also have rockwool batts in walls then was going to add doulble solid timber doors.
Was looking at resilient mounts etc but alot of time and effort to do.

Any feed back from people who have done similar would be great.

Hi kassan1973
i have just started looking into soundproofing my home ( 2 increasingly lound teenagers) and greenglue and some cost effective combination of boards looks the go. How did your installation go, what would you recomend
Cheers Bill

Excuse my ignorance, but what's "green glue' and what it's used for ?

Its a soundproofing compound like liquid nails but has soundproofing properties
Its mostly used in home cinemas

i am wondering if i am going to get a signoficantly better performance from using firecheck palsterboard over standard plaster board and should o spend the extra to get 16mm over 13mm thick board

layers being timberstud with rockwool + resiliant channel fixing = plasterboard layer 1 + greenglue + plasterboard layer 2

currently researching the best way to do the walls on my cinema, found this stuff made from foodwaste from what i can remember

theres also lots of products on the market, i guess its a matter of how $oundproof you want

Hi Broberts i have also found this product Barrier board which i will be using in cinema room.
The guys over at Audio trends Ringwood use alot of the Green glue as well.

Green Glue damps vibration. That is, it converts vibration to heat. Damping is one of 4 different elements of sound isolation:

Decoupling (like the resilient channel mentioned earlier)
Absorption (simple insulation)
Mass (the plasterboard is the best all around source for this)
Damping (visco-elastic materials)

They all perform different functions, and none replace the other in an application. Ideally for high level isolation, all 4 elements would be deployed.

The thicker board has more mass, and is therefore better for sound isolation.

Any new product that hits the market needs to have significant acoustic testing. Beware of claims that have no corresponding lab tests to substantiate.
