Green Glue vs Quiet Glue Pro - Soundproofing comparison
ฝัง
- เผยแพร่เมื่อ 4 มิ.ย. 2016
- Soundproofing rooms in our recording studio so we did a test with Green Glue, Quiet Glue Pro, Liquid Nails, Roberts Carpet Adhesive, and a few others when building our recording studio. Which is better? This video demonstration shows a non scientific comparison of my experience working with all of these. -
It should be noted that after the Quiet Glue Pro set up it worked really well. It took much longer for it to cure (4 months!) than the Green Glue did. Acoustical glue is an important part of recording studio construction and this is my experience dealing with these products and our simple testing.
I'm looking videos to sound proof my garage to convert it into a music room and this video really helps!
REALLY COOL TEST!!! I've been doing research too, & it usually comes down to bottom-line: amount of desired effect compared to cost. Watching your video would convince me to go either with green glue, or carpet glue ... that running cauk MESS will be a problem, not to mention the integrity of the physical connection between panels if the beads are running so badly that means that over time they will actually change dimension and "loosen" your lamination! YUK to the acoustic glue that runs. Carpet glue advantage could be use of different trowel configurations to adjust thickness of beads, putting down more material with evenly dispersed air-spaces seems to offer advantages in addition to big cost savings! You convinced me to look into carpet glue! For supposedly not being "scientific", I believe you did a practical real-world test that is very scientific. Best of luck with your studio!! Thanks for your intelligent honest post!
The magic to green glue is that it doesn't harden which is what stops the sound from transferring, more so than the chemical makeup. Went it hardens it becomes pointless, or counter-productive. When you understand that, then this test is actually fine. And, a HUGE thank you for doing this. I'm building a 10X10ft room withing my garage for a drum-booth. So, I've got help from the garage walls. So, I'm hoping the Roberts carpet glue will be fine. This was a great video.
This is excellent, thanks for your time putting it together.
You are welcome. I spent so much time going over all of the different options I could find and I figured I wasn't the only one doing that so since I was in the middle of a building process, what the heck...maybe it would help others out too.
Thank you very much for taking the time to put this together. This is a very clever demonstration. I was trying to figure out a way to justify the cost of Green Glue for a home studio project and was looking for a possible work-around solution. The hammer pitch is distinctly different between the Green and the carpet glue --suggesting the Green seems to do a much better job. I was wondering, however, about putting foam (or rubber) weather striping between the sheets in lieu of any of these products. Would love your thoughts on this? Thanks again. Cheers!
Yo the Roberts 3095 is Off the Chain! Really pulled through for us at our studio. for $40 for a massive container its a no brainer. Forget the green stuff and go for it. This second layer is solid as a rock at our studio...
Thanks for the update!
Can you give a rough idea of how much carpet glue is needed? Hoe much for 1 sheet? or how much for 10 sheets for example? Thanks!
@@3tjrunner3 go to home Depot and buy a 4 gallon bucket. it's like 40 bucks. and we'll get you approximately 10 to 15 sheets worth.
apply a thin layer like you would apply a very thin amount of peanut butter to toast.
This second layer is solid as a rock at our studio... I am assuming? you mean performance is solid as a rock?
Huge help this is exactly what i needed to hear
A wonderful non scientific experiment. Thank you very much.
Needed this. Good lookn out chief
Awesome analysis! How carpet glue per drywall sheet or per square foot would you recommend?
Would be interested in seeing how Dow Great Stuff Flexible Foam Drywall Gasket or the QuietSeal Pro compare. I realize those are meant for different purposes than sound dampening, but some of these tested products have different purposes as well.
Were any of these measured for acoustical differences, or was it just based on how they look and feel, and apply? Those factors are good to know for installation considerations, but I am most interested in the differences between them for sound dampening.
I actually did a bunch of testing with that stuff and it was a much bigger pain to deal with and because it sets up so fast was next to impossible to use.
We like the video... and you should care. 😎
So a great test would to be to build a little box, (just big enough to fit any portable radio or speaker or something) using each of the different glues.
Like a 2 x 2 box using scraps...
Then play the same song and have a DB meter in a stationary place read the result.
If I get to the point in my current studio build where I am ahead of the game I will try to do that !!
Thanks again man, great job !!!
Thanks for the suggestion....The studio is done and the isolation is excellent.
thank you it was very helpful.
The problems with running of the Quiet Pro seem a fatal flaw since it doesn't appear it ever stops running - so the sound absorption performance will continually decline as the thickness of the product will get thinner and thinner.
I didn't see you sealing all joints (wall to floor seemed unsealed).
Carpet glue might be the best poor-man's noise sealant, especally if applied much thicker than you applied it (maybe a notched tile adhesive trowel would work better).
Sure wish I had the interweb to learn about this when I built my house 25 years ago. Used staggered walls, foam and bat insulation. Worked quite well, but this seems easier, cheaper and provides more effective noise dampening
Thank you! I didn't know about this Batt insulation. Apparently it's very similar to other acoustic insulation, just easier to find in stores like Home Depot and Lowes.
All joints were sealed, even the floor/wall joints. The finished result is exceptional.
It all evens out - nothing at the top of the wall, but double at the bottom. There's likely a puddle all along his sill plate - but hey, it's an "exceptional" result. Oh my.
@@ArthurDentZaphodBeeb The cleanup from the few spots took less than 10 mins, has stopped running and the end result of the sound isolation is exceptional.
Good point about the performance continually declining as it gets thinner. It's definitely not a variable you want to have during application and prediction of effectiveness.
other then the adhesive damping compounds, what other methods did you use for soundproofing? Double walls, resilient channels, Roxul, staggered studs, rubber isolation pads?
We used about 100 bales of Roxul, dual layers of 5/8" drywall, solid stave doors with ADA thresholds. We did not use resilient channel, clips, or pads. We did stagger studs where we needed to though. I'll post a video of the isolation if I can ever get the time.
YES! In the name of Science and Audio Excellence! Roberts 3095 carpet adhesive for the cost/benefit ratio win! Thank you!
hey thx for the video....so did you do resilient channels as well?
No. We just did 2x4 framing for each room. All construction was done room inside of a room with no rooms touching....we did offset the studs between rooms though.
Just a thought, maybe using full coverage of the carpet glue, and combining half the recommended Green Glue amount could be a nice solution.
I posted this for another person that had commented and thought it would be good to share now that some years have passed.
Update...Isolation is still excellent. No glue seeping out of walls. That actually stopped a very long time ago and in the grand scheme of things was not very much at all. I think we used a total of 8 cases of Quiet Glue Pro (12 large tubes per case) and our total mess clean up from leakage would equal about 1/16th of a full tube. Clean up was super easy with Mineral Spirits so definitely worth the savings in my opinion. If you can afford the Green Glue, then use it. Quiet Glue Pro was much cheaper at the time and I think we also ended up using about 12 cases of it. I think it ended up saving me about $2,000 and because of my situation of funding it all out of pocket, at the time that was a big deal for me. The carpet glue was much cheaper for sure, and the areas we used it in were not critical (lounge, restrooms, storage rooms etc) and since those areas were not super critical, I cannot say how well it worked compared to the other options we played with. Even our storage rooms, lounge, and restrooms were also treated with double layers of 5/8 drywall+glue of some kind.
Thank you for the video. Just wondering how the carpet glue is holding up?
I'd also really like to know this
Yeah, let us know about the carpet glue now?
Would be nice to hear how it's performing over time!
The carpet glue seems to be holding up very well. Not running at all. I have no scientific testing to see how much of a difference it has made between the other glues but its not running and the isolation in the studio is excellent.
@@TexasDiamondSRanch Its excellent/
Good data thanks.
what is this green glue thing? is it a silicone seal glue? is there any other option?
*Anyone else out there with experience with the Roberts 3095?* About to do a second layer very soon!
Thank you for this video. I think I'm going with the ROBERTS 3095. Ridiculous cost savings vs Green Glue for dampening my drywall.
and with none of the sound proofing properties. what a deal! or DOES it actually work? Generally seems like bonding the 2 sheets with something rigid would actually transmit the sound better from one sheet of drywall to another.
Joe Moccia the point of a glue that remains viscous is to absorb vibration from the sheets of drywall and prevent transfer of sound through the sheets. Green Glue is insanely overpriced for the few decibels of difference it makes. If the Roberts glue bonds the sheets and remains viscous, it will have a similar effect as Green Glue, plus at $38 for 4 gallons, I can easily justify putting it all over the sheets and not feel like I am throwing money in the toilet
@@MocciaJ It's not rigid. It's in the documentation and the Manufacturer confirms it.
Jacob Smith toilet ring wax, or 100% silicone mixed with a little rubbing alcohol so it doesn’t fully cure.
Can you give any updates and how it went now that this comment is a year old? I'm about to use it!
There is indeed a reason to use the green glue. It's intended to go between slabs of sheetrock and those are to be screwed together, many years later it will still be elastic whereas the other BS will harden and you lose your soundproofing.
Surely screwing the layers together shorts out the whole system, and causes vibrations on the layer facing the source of sound to transfer to the layer behind it.
please tell us the product ari@Ari Lin
@@joeanon3216 Thats not what it is suppose to do though. The sandwich is just to increase mass and make it more air tight and the stuff inbetween the sandwich is to even out the frequency response and generally dampen the whole sandwich.
You then need an outside layer, either another sandwich or say a concrete wall.
You have to decouple the whole sandwich and it's support structure from the outside layer, the layers of the sandwich itself have to be coupled, thats the whole point of the sandwich.
If your inbetween material hardens then it will lose it's dampening quality but otherwise not make things worse.
If you build your inner shell massive enough you don't need any sort of sandwich or limp mass. The sandwich technique is just to build the room within the room on the cheap without having to build a concrete bunker within a concrete bunker.
I agree. Green Glue is the best. We used it in the most critical areas and used the other compounds in the less critical areas.
Silicone
Please let me know... the Robert's is about as good? I am trying to figure out if a 4 gallon bucket of it would be enough for a 8ft×13ft room??
Thank you!
Did you eventually try it? I'm interested in using it in a couple weeks for a while studio build but I don't want to screw it up!
Was there any difference between Robert's 2057 and 3095? Your small tub was 2057, but your big tub was 3095. Why did you switch? I'm thinking of using some sandwiched between 1/8" tempered hardboard layers for a light weight speaker. I built some about 7 years ago that still sound good where I put a lot of wheel bearing grease into roofing asphalt (tar). I let the original solvent evaporate in the Texas sun with the lid of the can loose for a couple months. It never hardens, but was a lot of work to make up. Roberts makes about 50 different types of adhesives.
From what I can see 3095 is a carpet adhesive whereas 2057 is a vinyl tile adhesive. 3095 is a lot cheaper.
It was a test run to see if the consistency was the same. Which it wasn't.
SO KOOL THANKS SO MUCH ☺️
How do you apply the carpet adhesive? over the entire sheet or in the same (non) pattern that you would do the green glue?
We used a trowel like they would use to apply it onto a floor. It worked really well and even left some little ridges that sort of looked like a on old LP Record that made it appear to work even better. I was really surprised at how well that stuff works!
thanks, I did the same and just finished texture last night so I'll let you know how it works
please do as I am getting ready to hang my double drywall and would love to save that much money
when are you doing yours?
How did yours turn out?
I just had a quick read of the attached comments, and maybe someone else pointed this out already, but the point of Green Glue is to take advantage of the energy lost by shear force. It's not at all about floating one panel from another.
Any chance you still have that panel a years later and can give a recap on what the glues are doing now?
Yes, Can we please get an update. This is very valuable information to have for the AV community
I threw that thing out at some point. Sorry. Would have been good to keep around to see how they looked after a couple of years.
@@Preezyfosheezy Update...Isolation is still excellent. No glue seeping out of walls. That actually stopped a very long time ago and in the grand scheme of things was not very much at all.

I did a small room for a kennel room in my house because I'm a dog trainer. I like the idea of the carpet glue I never thought of that and I have peeled old carpet up in other demos that were years old and it was still sticky. My only comment after watching this video is How did you get the quiet glue off of the surface of the drywall so you could finish the paint? We were really careful to not get the green glue on the surface of the drywall because I can't imagine how you would clean that off. If I do another room I think I will really look into the carpet glue.
He used mineral spirits to clean of the ooze.
thanks!
Regarding the Robert's carpet glue, does it take longer to apply? Looks like quiet glue and green glue can be applied very quickly. Time is money...
No. Its very fast just like the Green Glue. For the carpet glue we used a trowel with a serrated edge which gave it a cool ribbed texture but it can be messy to work with as it gets exposed the the air and gets stickier. But it never fully hardens so thats the positive. For the Green Glue we used large caulk guns and they were quite fast as well.
I know that Green Glue says to use 2 tubes per 4x8 sheet.. thats $40 at amazon prices. Not a big cost in the overall Do it ONCE as BEST for the RESULTS. My question is knowing how to spread an even layer with a tile trowel wouldn’t it be better to use the 1 tube and spread it evenly so the GG layer is the same thickness? I use industrial sealant in building metal to metal at work and using more just is a waste. I know that GG needs a certain amount to be the layered cushion in between the drywall. But more than what evenly spreads is a waste.
Do you have any thoughts?
That quiet glue looks like a mess. I'd pay the premium to avoid having to cleanup all that peanut butter
EXACTLY...doing more work than needed to clean up and not knowing where it will run...gotta be a PIA
You just need some bread
@@vilo3454 Its actually not bad at all. Mineral spirits and its cleaned up in just a few seconds. Totally worth the savings and the end result is fantastic. My isolation is easily the best in town by a long shot. I'll try to post a video of it one of these days.
I was reading in another thread that someone had the Quiet Glue Pro running out, and it was because it was 2 years old QGP. Is there any chance you had expired product? I'd like to save some money, but I'd rather not have money run out of the walls :P
The amount that runs out of the walls is very very minimal. Totally worth the savings for me. Easy to clean up so I just didn't bother with clean up until construction was done for about a year. No issues at all now.
I used a notched trowel for the outdoor carpet glue on my most recent project.
I was thinking of doing the same. what size notch did your trowel have, and did you cover the entire sheet? Any final thoughts, four months later? Thanks in advance
@@sfn4702 I used a 3/16 V-notched trowel..
@@barrymarson9658 thanks Barry!
Does green glue block incoming noise too? Or just prevent noise from going out? I have crazy neighbors and I can't knock down my shared wall with them so I can only add layers
It will work both ways between layers. Its kind of like jelly sandwiched between two slices of bread. It doesn't matter which side of the sandwich you are looking at, the jelly is still the same.
@@tacomarecordingstudio9366 Thanks! If budget is not a concern, what is the best I can do? Thick layer of green glue + quiet rock? How does it fare against impact noise? Somehow I can hear my 500 lb neighbor walking on his heel and my room shakes. I own a brand new condo unit and the quality of everything is driving me crazy.
nice video, but use wide angle lens in that room unless it is for closeups and stuff.
Yes but more important what was the best for NO ODOR
The odor was completely gone in about a month. And since we had so much other trim work to do before opening. it wasn't an issue at all for us.
Liquid nails makes an acoustic version, did you try the acoustic version or normal stuff?
I did try the liquid nails and it was a lot like the Tremco. Next to impossible to use .
What Tremco product did you use in this video? Thanks in advance
great video by the way.... I will be using a mix of Green Glue and 3095
Tremco Acoustical/Curtainwall Sealant - aka Black Death. Don't use it inside - it off-gasses and smells of petroleum.
im sorry, but i didnt get what was the black glue, can u pls post the name? thanks
It's Tremco Acoustical/Curtainwall Sealant. AKA Black Death - it's a petroleum-based product that smells and off-gasses and is miserable to work with since it gets everywhere (stringy/clingy). Green Glue is a far more friendly product with no smell. I would never use Tremco inside a living/working space. I don't know where he found Tremco so cheap and Green Glue so expensive. Can find Green Glue Sealant (white) for $12.50/qt tube and Green Glue Compound (the green stuff) for about $14.50 when buying 5 gal pails. Tremco seems to be about $17 per quart tube.
@@ArthurDentZaphodBeeb I agree. That stuff was terrible in every way but we found some and decided to give it a try just for comparison.
anyone ever try plain old GE silicone calk? it does not dry hard? As for the carpet glue how would it be in 5 to 10 yrs? What about thin foam sheet? oh well I'll go with the carpet glue as I know it works. Building a downstairs room that needs to be as sound proof as possible. Any recommendations for flooring? I know, carpet, but what kind? What kind of pad?
Try contact adhesive.. Pure rubbery texture when the solvent evaporates off..
How many tubes can you get out of one bucket?
I don't know as we only biught buckets of the carpet glue. I think there was documentation on both manufacturers websites about the ratio of cases to buckets but I cannot remember what that was.
what are the long term results?
So far so good! Isolation is still exceptional. Quiet Glue Pro only ran for a couple of months and clean up is super easy so it was definitely worth the savings at this point. At least for me it was.
How effective, would you say expanding foam would be?
I would not use expanding foam for going between layers of drywall as a replacement. I have probably used about 60 cans of the various types of expanding foam in the studio build and repair of our old building here and I would never consider using it as a replacement for Green Glue or Quiet Glue Pro. It comes out really uneven and expands unevenly as well.
Doh! Too late i already put expanding foam between two sheets of drywall. I don't think it helped at all and may have made the short wall like a drum.
Thank you very much. I considered another layer but I gave up on trying to block the sound in this duplex. I think the sound may be also traveling through the ceiling and through the floor and basement wall. I own both sides of the duplex and am thinking the best way to eliminate sound from one side to the other is to sell the house and move deeper into the country.
I live out in the country too and there is no substitute for distance between neighbors!
Joe Kotarsky 😂. Really I'm glad you informed me about this because i was just about to give it a try and let everyone know about it but thanks for being the test dummie and beating me to it.
Honestly I was additionally going to add some silicone over the beads of spray foam theoretically giving a similar property as the green glue, but I doubted this setup as well.
Upon a little more research about the green glue and it's elastomeric properties I figured the next closest thing is mixing cornstarch with water, but was afraid of mold issues.
Important question: did you use standard liquid nails or liquid nails acoustical sound sealant AS-825? Big difference in the two.
I actually ended up trying them both. The Liquid Nails sound sealant was a huge pain to use. Much bigger pain than the carpet glue. Not worth the effort at all.
What was the Black stuff? Good alternative or not?
The black stuff was Tremco Acoustic Sealer. Terrible to work with.
I am soundproofing my basement apartment, and watched your video, you said " Carpet glue doesn't do exactly the same thing but it is much cheaper and much easier to find. I would never claim that carpet glue does the exact same thing but it does seem to work really well esp considering the cost savings!".... would carpet glue be a good solution for a basement apartment? I am looking to buy the glue this week, really need your opinion. Thank you
No idea if you did your construction already but I would advise against using any kind of glue. Put self adhesive MLV in between the two layers of drywall, same for ceiling. Decouple your support structure from the outside wall and ceiling. Would need to make a floating floor too, otherwise it will all be for naught mostly.
I was quoting what I was told by a world renown studio builder. It may not do exactly the same thing but it is still plyable and was instantly available when we had an emergency need to have a wall done asap....
@@tacomarecordingstudio9366 are you referring to Dave Rochester? Because I actually emailed him last night about Roberts 3095 vs Green Glue and he said he does NOT recommend anything other than Green Glue and has NO experience with Roberts.
??? I'm confused now
Should have used THX soundproofing drywall! it's the same used in movie theaters. It's an inch and 3/8 thick. Then green glue and layer with quietrock! I've done several theaters and music rooms that way and you will never hear a sound! people always trying to save money. just do things to the manufacturers specifications and you'll never have an issue! And for crying out loud, the green glue is available in 5 gallon buckets for under 300$
Hi, I want to build a room as quiet as I can Afford, in my basement. Planning one 2x4 'staggered studded" wall, so would I put the THX 1 3/8 on the inside of the room, or on the outside of the 2x4 walls? Quietrock x 2 with green glue in between the two layers (sheets) of quietrock on Inside of room, or On the Outside of the 2x4 walls. Also, which product for the ceiling? Quietrock 525 Or Quietrock 545 for Ceiling?? I would also use acoustical Caulk around light, electrical outlet boxes..THANKS!
Quietrock is three times more expensive than 5/8" drywall. If a person doesn't have the budget for Green Glue, they clearly don't have the budget for Green Glue + Quietrock + 1 3/8" thick drywall. Telling people to spend money they don't have isn't helpful.
Your application doesn't make sense. It will be extremely costly and this whole video is about saving cost. The double 5/8 with green glue is a proven formula and good enough for this application. After all, 5/8ths is far cheaper than THX drywall. Two layers of 5/8 with GG is cheaper than one sheet of quietrock and more effective.
Thank you for making sense.
Thank you, MudSlingr! MUCH usable information!
How about mass loaded vinyl? I've heard great things about that.
Mass loaded vinyl was interesting to me too. I couldn't find any close by to do a test with. Wish I could have though. I think that stuff would be great on doors when adding another layer of plywood.
@@tacomarecordingstudio9366 I know it's been years since your original video and comment but here is some info on MLV
It definitely works. It's not like green glue's "maybe it does maybe it doesn't"
Heavier, measured in lbs per sq ft, works better but is more expensive obviously.
The best way to apply it is to hang it as loosely as possible. Usually attached just at the top with a couple of fasteners to make aure the MLV hangs loosely in the stud bay. Then hang the drywall placed over it. Best hung MLV i saw was on the inside of a double wall were the hung it between the walls. Hung over the top plate of the wall and down like a shower curtain.
Also the cheapest and most effective per dollar sound mitigation is a double wall with regualr batt sound insulation and then double layer 5/8" drywall on each side.
@@PandorasFolly Hey therer. Yeah that is what we did here. Each room is it's own structure (including the hallways. We offset the studs in adjacent rooms as well. We filled everything that wasn't an intended air gap with Rockwool, and then used double layers of 5/8" drywallon every wall and ceiling with green glue in between the layers. The isolation turned out really good. I do not know the final measurement on it though.
Why not just use MLV? Works in a similar manner while also adding much needed mass to lower resonance frequency of your drywall sandwich.
What is MLV ????
@@oldowl4290 Mass Loaded Vinyl. Some places its hard to come by. I tried to find some locally and did not have any luck.
What type of carpet adhesive did you use?
Roberts 395 Carpet Adhesive.
Here is what I did for my walls..
*2by6 walls
*Rockwool safe and sound
*6 mil plastic
*3/4 inch Sonopan
*Rubber shims
*resilent channels
*5/8 quiet rock
*Outdoor carpet glue
*5/8 Green board
STC of over 85, case close..
Watch the acoustic fields vid on greenglue ect., the wrong way costs more, may be ineffective, cost time, end result look on channels that feature companies not individual blind test without result or measurement, some engineers have channels also, those are also great sources.
You need a system that uses the green stuff only where actually needed. 1. Mass, you need it for sound proofing. 2. Air tight. 3. Fire proof to head off landlord objection would be nice.
Give me s budget, I think I can get this. Can anyone try?
How did you apply the carpet glue to the sheets of drywall? And how thick did you apply the carpet glue
Thank you
We applied the carpet glue using a trowel that has a serrated edge and put it on as thick as the serrated edge would allow when dragging it across the drywall.
was there a STC test between GG and Carpet Adhesive?
@@brentbarcus7650 No. Like I said at the beginning...non scientific.
It seems like 100% silicone would do the same thing🤷🏻♂️ It looks like it just needs to stay soft to do the job?
I thought the same thing but I think the problem is that it hardens just enough that it isn't as effective. The carpet glue was pretty awesome and very cheap! We used it on the lounge against the first wall inside of the building out of necessity. Still worked great.
How about toilet wax rings?
Following
It seems like the money you saved on product will quickly be absorbed by labor costs trying to clean off all that quiet glue that leaked out. On a project of that scale it seems silly to worry about $2k if it's a superior product.
Hi John. It seems silly to worry about $2k difference in cost unless you are paying for the entire build out of your own pocket with no bank loans. The savings was worth it to me as there seems to be no difference I can really tell between the rooms we did with the Quiet Glue and the Green Glue.
As a follow up. The quiet glue has stopped running about 6 months ago and the amount that ran out was very very small. So I would go with the Quiet Glue again and save the $2K.
Hello sir. Can you give updates about the Roberts adhesive? Still tacky?
@scoobtoober29 would it be worth to use this stuff on the studs as well?
@@levijessegonzalez3629 I would think so....
@scoobtoober29 Is it better than no adhesive?
@scoobtoober29 you've done any tests I mean?
@scoobtoober29 good to know. Well I'm doing two layers of sheetrock so I actually wouldn't mind some adhesive properties for the sheets...
Do you think I should apply it and immediately put the sheets together or let it dry a few minutes?
You wait for some of the moisture to dissipate?
How about silicon sealant?
VisionsofRaptor why silicone? Why not every possible one? Gorilla, crazy glue gel, etc etc. Someone
please do proper tests. I'm hungry. Bye
But seriously..... why not, whey it dries it stays flexible, doesn't transmit vibrations to another layer of drywall, I don't see even one reason it is better than 100% silicone.
@@czodzy i am completely agree with you i was thinking the same thing why nobody talks about 100 % silicon like this guy, i am sure he know what Silicon is but he is keep saying Green Glue
It looks like the elasticity of the Green Glue acts like a shock absorber, meant to remain pliable yet have some adhesive properties. I would think that using it sparingly ( strips several inches apart) would help the de-coupling factor. If the Roberts carpet adhesive is applied with a notched trowel, the further the notches are separated, the better, say 2 inches as the closest . It results like a staggered stud double wall where the less contact....the better. Air is easier to compress than wood studs or gypsum board. J K
Why so much scrap drywall?
We didn't really have much scrap. We hung 540 sheets of drywall. That is not a joke.
Seems like the green glue is best though.
It is. We still have areas where the Quiet Glue is seeping out of the walls and onto the floor but it does work really well. If you don't mind the running of the Quiet Glue you can save some money over the Green Glue but the trade off is definitely the running. I didn't sense really any difference between the rooms we did with Green Glue and the rooms we used Quiet Glue.
There really is no substitute for GG and its really the cheapest solution STILL! And no i dont work for GG but I did my entire media room with it and the results were real,,, works fantastic for containing low feqs from a subwoofer etc.
Here is some information you may want to consider before using Green Glue. The following links are the the site of Dennis Foley who owns a company called Acoustic Fields.The following statement are the words of Dennis just to give you an idea of his background in acoustics and design.
"I am an acoustic engineer with over 30 years’ experience in the business. My technology has been used in Electric Lady Land Studios, Sony Music of New York, Cello Music and Films founded by Mark Levinson, and Saltmines Studios in Mesa, Arizona, along with hundreds of others."
I found this interesting on the topic of Green Glue as explained by Dennis Foley of Acoustic Fields.

Horrible drywall placement, a lot of seams to seal.
I can't see what green glue will do. I don't think it works.. outdoor carpet glue works best
carpet glue ftw fuck the rest
just use 1/2inch finish grade ply wood instead of double wall of sheet rock with that green glue. It's just as, if not more effective.
If this were true, all pro-studio designers would be recommending it. There's no substitute for decoupled mass in reducing sound transmission.
@@GrantConklin Not necessarily. People use what they have been brainwashed to use. Not everyone knows every material available and every way to reduce sound transmission. You think Corning's 703 is good for low frequency absorption? It's widely used, but it's hardly going to do much below 100hz, let alone down to 50hz, 40hz or below, yet people use Corning's 703.

Don't have this McDonald's mentality. Just because it's the most popular doesn't mean it's the best. It typically isn't.
You can do layers of finish grade plywood and layer other materials that are going to be better than sheet rock with green glue and still be cheaper and more effective.
The problem is you haven't really spent any time doing the research on what materials are available and how effective they are.
You also missed the point that people need to do studies to figure out what frequencies and amplitude they need to stop before they decide how to construct the walls and what materials to use. Everyone has different problems to solve and one doesn't solve every problem. No one method is going to work for every situation.
@@GrantConklin Not all pro studio designers know every product on the market, let alone every type of wall construction. Your assumption is that they all know everything on the market and every possible way to solve a problem.
Also, even major top end studios have had to completely redo their rooms and they STILL have issues that have to be addressed because whomever designed it didn't know everything.
@@Oneness100 It's nice to know that you know me and all of my assumptions so well, having read my one short comment. I've been using a spreadsheet that shows the NRC values of 450 materials for several years now. If you'll show me STC values for your plywood wall suggestion, and I'll be happy to learn from that. The fact is, sheetrock is heavy, and relatively cheap. In fact, where I live the cheapest finish grade 1/2" plywood is nearly 6x as expensive as the same sized drywall, and weighs about 20% less. I have yet to see finish grade plywood at anywhere near the price of sheetrock. When I find such a thing, I'll be happy to use it.
Perhaps my statement that "all" pro designers would be using plywood if it were best is a little over the top. Because you're correct -- no one designer knows every material available. But I'll stand by my statement that there's no substitute for decoupled mass.

If anyone is interested, here's a test to see whether Green Glue or carpet glue works better... th-cam.com/video/455o9NuvWWw/w-d-xo.html
Is that diarrhea Doo Doo on that board?
Has anyone done any proper tests? You would think that by now some independent somebody or company would have made a proper standard testing of all top products and published the results clearly. Why do we have to watch a hundred useless videos to end up with nothing but a bunch of conflicting lists of info and end up having to guess or go with the guy who made the least obnoxious video. And what are we going with? Useless results of useless tests.
QuietRock and Green Glue both have their official laboratory test results on their websites. Green Glue requires three to four sheets of 5/8" drywall to achieve their higher STC ratings. That's a lot of labor, material and extra inches on your wall assemblies. They also apply noise dampening putty to each screw, to achieve that result which I don't think the average homeowner or contractor would do. Quiet Rock offers the highest STC by far in a single sheet without having to cover every screw with putty.
Liquid nails?? Wtf?? Lol....
With so much corrections, verbal and notes correcting in the video, nobody gets your sayings....👎
I'm glad you don't care because your soundproofing comparison was pointless.
This video is way too long. Use your common sense. The Green Glue works, but their installation instructions require more than needed. What you are looking for is a reduction in sound transfer between sheets. My suggestion is use less glue. Take some styrofoam packing peanuts, dip them in Green Glue and randomly place them between the drywall panels. The peanuts will increase the space between the panels. You want the outer panel to vibrate without transferring sound to the panel it is glued to. The more attachment points, the more the transfer of sound.
Your statement intrigues me and totally makes since. Have you attempted this? I am very interested in your technique and results.
