Who is Using Green Glue?

[Ted White]

Is Green Glue commonly used here? I don't see it referenced much. Not sure if it's a price or availability issue.

For that matter is Maxiboard, standard double plasterboard, resilient clips, etc. used?

Thanks

[Earthworm Jim]

Green as in ozone friendly or green as in colour? When it comes to things like glue I prefer to use the manufactured chemical kind as I feel it works better you also get a nice buzz in the room

[Ted White]

OK so Jim would prefer some solvent to be added for the work buzz. Got it.

Green is the color and nearly zero VOC, to answer that question.

I'm not sugesting people use Green Glue, rather I'm wondering IF people use it

Thanks

Ted is Green Glue used for sound proofing dry wall? I have heard it mentioned and used several times in the forum.

[Ted White]

Green Glue and the other items I mentioned are all used for soundproofing, yes.

I'm curious what materials and methods are commonly used in the UK

[andicapped]

no green glue used in my room (couldn't afford it), i've still double plasterboarded 12.5mm each sheet and insulated.

[Ted White]

OK so you used Mass as primary isolation method. Curious if the walls are standard timbre framing + insulation?

[Brien]

"OK so you used Mass as primary isolation method."

Primary seems, what is it, like there are other methods? Mass is required to contain sound, no other options exist. Maybe a vacuum.

Green glue isn't mass. It is, as you already know, a visco-elastic product designed to damp sheetrock. If I were to hazard a guess, one of the main reasons that this is not a component of sound isolation builds in the UK is that, for the most part, they build with concrete, stone, brick and heavy materials that far surpass a sheetrock type residential wall of a home theater.

For the most part,

i imagine it don't get used an awful lot as it is redicoulously expensive at £15 a tube

[andicapped]

my room is a "room inside a room" i have created a box inside my attached garage so the internal stud walls dont touch the external brick. from the inside out it goes,

plasterboard--plasterboard--wooden stud framing-- filled with insulation (very very dense rock wool) -- 2-3inch air gap---brick wall.

sound can't be heard in the house or outside even at very high volume, something i was very concerned about. i dont know how much difference green glue ould have made to this but i thought GG was designed not for soundproofing in the sense of sound escaping but to contain sound in the room so it's not lost on the fexability of the walls.

maybe i'm wrong

That's not quite right. Other obtions certainly exist

Thanks for the refresher. Mass is a component, but only 1 of 4 components. So yes there are 3 other highly advised components: The 4 Elements of Room Construction


Reliance on only 1 of the 4 will limit performance.



Quote Deansocial: "i imagine it don't get used an awful lot as it is redicoulously expensive at £15 a tube".

Wow, I agree. It sells for half of that in the States.



Quote andicapped:

"my room is a "room inside a room"" OK then you also used decoupling in addition to mass. A significant move beyond mass alone.

"...filled with insulation (very very dense rock wool) -- 2-3inch air gap-" OK then you also used absorption.

That's what I was originally getting at. You would have deployed Decoupling, Mass and Absorption in your build. Nice job.

Damping materials lower the conduction of vibration in building materials. Properly installed, they are a component of a larger soundproofing plan. Any of these Elements will address vibration that has entered a wall or ceiling and is racing to other building components (like the wall of your home).

[Brien]

"Reliance on only 1 of the 4 will limit performance."

Agreed, but that was not your statement.

Just for fun....

I can isolate sound with distance. But this is not as feasible anymore as it may have once been, due to the swelling global population. My theater music can be heard outside at 100dB from 1 meter away. In order to drop the SPL to the acceptable noise ordinance level of 75a, the distance required would be 19 meters from the source to the property border, to reduce this 100Db level to a lawful 75dB.

But that isn't really controlling sound. That is more sound controlling you

I looked at your website(I knew it was coming) and I still stand behind what I said. Mass is the the only thing that will isolate sound.

If I have a 15cm (6 inch) thick concrete wall enclosure with floor and ceiling of the same thickness, the sound levels can be reduced, contained and isolated.

No damping required.
No decoupling required.
No absorption required.

I do agree that these components are useful as a means to achieve a goal but if the distance factor cannot be achieved, then mass will be the only other item that can be used to sound proof a home theater.

[Ted White]

I don't wish to argue semantics, but mass is one component of 4 available. It's a function of how the 4 are deployed.

Given dramatic mass, you would not need decoupling, damping and absorption.

Given dramatic damping you would not need the other 3 elements.

Given dramatic absorption you would not need the other 3 elements.

But the real world does not generally allow a tremendously large application of only one element due to practicality and cost. If you were to review the construction of very high performance facilities, you would find that most deploy at least 3 of the 4 elements in some fashion. Just like andicapped did. He used 3 of the 4.

I am in process of clearing out my garage ready for construction of HC room and was thinking of the "room within a room" thing

Can you clarify how it is done, is it

Brick Wall of Garage
Plaster Board attached to that
Wooden Frame atached to that
Rock Wool compacted into the above frame
Plaster board attached ontop of above ?
