- Using Safe'n'Sound insulation, resilient channels, Green glue and specialty drywall for cutting the noise from your neighbour.
This is a step by step video, highlighting the proper installation details of the layers of the soundproofing assembly.
Hi Martin, just wanted to let you that the outcome of the work you have done exceeded our expectations on two levels. First and foremost, the quality of your craftsmanship and your recommendation for the "Cadillac" model for soundproofing. Secondly, because of the former, the reduction of airborne sound was entirely eliminated and the impact sound (which was the reason for the soundproofing) has been reduced by 75%. The soundproofing keeps improving with time. As the curing of the green glue progresses, the soundproofing increases.
Great to hear. Thank you very much for the feedback. Martin
Hi Nikkor, it's been a year. How is the sound-proofing? Especially compared to how it was before the changes. Thank you!
Resilient channels on the wall are installed upside up-the nailing flange should be on the bottom, so when sounds travel the gypsum wall pulls channel form the stud. See Baileys installation video
The channel installation is upside down. The weight of the wall is supposed to pull the metal away from studs not into studs. I also question the parallel installation on the drywall but more of am issue us the flange needs to be on bottom
What a great video. Not a bunch of talking about stuff that's irrelevant and really helpful explanations, thanks!
Thank you. I am glad you enjoyed it.
As pointed out previously, always install resilient channel with the screw flange facing down. It really doesn't matter here on this job though since the double framed wall already accomplishes the decoupling of the 2 wall surfaces. It'll still give a little improvement with the panel being allowed to resonate undampened.
Honestly the best and most straight forward video out there. Thanks
Thank you very much for watching.
Yet done wrong
Hello Jason, would you please share more details about what do you consider done wrong? Much appreciated.
The r c channel is hung upside down so it doesn’t pull the flange away from the wall, giving u your 1/2” air gap. We were training guys in the field on how to install it, and pulled up your video and of course everyone was telling us we were wrong. After going through Clark Dietrich the way it’s done in ur video is wrong and is only a furring channel the way it’s used in ur application, it has no sound or stc application.
Thank you for taking the time to reply.
I was told many times that the res. channel is side down. My bad. That's how I learned it from others and should have looked into it more.
But I made sure not to hit any stud with the screws when hanging two layers of drywall, which I had seen many times before and IMHO is more detrimental to performance.
The assembly performs exceptionally, mainly due to the SilentX drywall and Green glue.
Thanks for your good video. Appreciate it.
Hello Richard, thank you very much for your comment.
Thanks!
For anyone reading this: if you’re doing this for your neighbours party wall you’ll still here A LOT of noise using this system.
You need to inject the ceiling with cellulose,
install Rockwool in the walls,
install resilient channel on the walls,
install sonopan or any soundboard out there made of wood fiber-
finally for the best results use an acoustic gyproc such as SilentFX which is a 5/8 2 layer gyproc with a gel in between. It weighs 100 pounds a sheet and it has great results.
Those are my 2 cents.
You can add 2 x 5/8 but I don’t plan on selling any of my properties so I’d rather save the space
Sonopan actually helps very little in reducing the noise level through the wall. Definitely not worth the cost.
It looks like your removed the center sheetrock fire separation between the two walls. Isn't that going to be an issue for the fire rating of the wall?
Thank you for watching my video. There was no drywall between two staggered walls except for the piece covering the floor and ceiling struture thickness. If you look again, you will see it. This is essential two houses side by side. We have changed insulation in the neighbors wall too to achieve maximum effect.
The fire rated drywall (two layers of 1/2" drywall) is on the outside of the wall - inside the room.
Also, common misconception is that fire separation stops fire. No, it is designed to hold the fire for period of time to allow for safe evacuation. Hence the 30, 45 and 60 minute rating, which depends on the type of structure.
since you use green glue on the ceiling to wall joint, do you need to do mudding and taping on the same joint?
Yes, you do need to finish the final layer of drywall so you can prime and paint the wall.
Will this work for neighbors barking dog? I'm having issue with my next door neighbor's dog, I can hear the howling through 2 rooms! I read online a dog's bark can be up to 100db.
Thank you for watching my video. If you go down in the comments, you will see my client commenting on the performance of the assembly.
Can it Waldo work without touching the existing wall? Only the 2 layers of dry wall with green glue?
Hi there, I am not sure if I understand your question correctly. But of course, it will work even with a 2 layers of regular drywall with the Green glue. We were going for all in, Cadillac version of the soundproofing assembly here.
This is perfect this is the exact situation I’m in. Did you use cellulose insulation? Also did you add insulation to both your wall cavity and theirs or just yours?
We did use the Safe'n'Sound Rockwool insulation in both wall cavities, ours and neighbors as well. On the video I am focusing on highlighting the proper details and techniques to maximize the performance of the wall.
Did you use single or double leg resilient channel, and is one better than the other? Why are there two types?
@@eols2190 Edward, we did use the resilient channel, which has a single leg with perforations along the bend to allow more spring between the framing and the drywall attached to the channel. The two leg channel you are referring to is not a resilient channel. It is used to make a frame for suspended drywall ceilings, usually in commercial applications. This channel is attached with screws to the C track. Do not use it in soundproofing scenario.
Is resilient channel for ceilings single legged?
I believe the resilient channel is only one kind, used on walls and ceilings but look up the manufacturer.
shouldn't the RCs be installed with the flanges at the bottom instead of at the top of the bar as you have it?
Yes, it should have, you are right. It was pointed out in the comments previously. But great care also has to be taken to make sure drywall is not fastened through the channel into the studs (specially on 2 layers wall) which negates the resilient channel purpose and unfortunately happens too often.
I am from Australia and looking to buy reselient channel by Bailey. Can you please advise where did you buy from in CA?
The resilient channel is a common item in the building material stores. You should be able to find it in Lowe's, Home Depot etc. Every drywall supplier should have it too.
does it matter whether installing the drywall panels horizontally or vertically?
It should make no difference if you overlap them properly for acoustical performance.
How do you cut the holes for the electric boxes?
Using the drywall saw as on a regular drywall installation, but the box is covered with the Green Glue caulking after mounting to dampen the sound.
Is there a need to put the drywall up horizontally? Could you put it up vertically?
Thank you for watching. The drywall orientation doesn't have any effect on the performance of the wall assembly. You can install it vertically, no problem.
can u actually do one layer with MLV behind the BATT?
Sorry, I do not understand your question.
can you install resiliant channel over existing drywall?
You can if you know the location of the studs.
In the video you are isolating the room from the sound coming from the neighbours. What if you want to achieve the opposite - i.e. to reduce the sound escaping from the room. Say you want to isolate a loud studio so it does not disturb the neighbours. Should you do all the same steps but in reverse order?
You can do the same thing. If you are building the sound studio, you should be looking to do this assembly on all walls and ceiling too.
@@renovationtoperfection That helps a lot. Thanks!
Good video. In what country was this project carried out? Is it necessary to apply to Building Standards for permission to do this work?
Ontario, Canada.
Where in Ontario are you located i am looking to sound proof my bedroom in a semi detached house and i would appreciate if you can put your contact details. Thanks

I was hoping to see the neighbor's reaction to a party next door.
LOL
Could you have use the resilient channel between the two drywall pieces for better results?
You could but I do not think it would yield a better results. The green glue between the drywall sheets or use of Silent FX drywall is what makes the difference. Everything else complements the performance of the assembly but of its own doesn't do much for the sound reduction.
I just pinned the client's evaluation of the performance as a top comment.
So any additional green glue between the sheets ?.. sound insulation, resilient, 1/2” fire gypsum, gg tube, silent fx?
What you just suggested would be even better performing assembly than I did. Silent FX drywall is basically 1/2" version of factory made two sheets of drywall with the Green glue in between.
great video, are you by any chance from Czech Republic ?
Yes, I am.
How heavy shelves or cabinets can this hold?
Hello Gregory,
this was a party wall in the living room and we didn't hang anything on it but it is 1" thick drywall layer. I belive you can hang just about anything on good quality drywall anchors as they will be fully embedded in the drywall layer and have more holding power than regular 1/2" drywall. But do not try to locate studs fir screws as that would greatly diminish the sound proofing characteristics of the wall.
Aren’t the resilient channels upside down?
You can attach the channel either way. I am installing my channels hanging down (screw on the top) for the drywall to hang - pull down on the channel to keep it tight to the framing.
Renovation to Perfection doesn’t the channel touch the stud on the bottom side under the weight of the plasterboard? I think if it touches it diminishes performance
No, it doesn't. If you look at the channel's cross section, the screw flange is longer than the other end. When drywall sits flat on the wide part of it, the bent edge is around 1/8" above the stud surface. Which is the principle of the channel.
According to Bailey (Resilient channel manufacturer), the flange must be on the bottom, not the top. Even their website states this
@@lmengel67 Thank you for clarifying.
Well done
Thank you. Acoustical improvements are pretty tricky to pull off and if took me quite a few years to get a grasp on what works, what doesn't and why.
Can i ask how much this job cost?
This was a one day project, done in 2019. I wasn't finishing the drywall on the wall. Materials $1,100.00 , total 1,900.00 CAD with taxes in. Ontario, Canada.
RC is upside down. I will be doing this today
Yeah, I know. Thank you for watching.
The soundproof drywall is the same as two quarter plus green glue
I know. But the client wanted ultimate solution and requested this.
That's gotta be at least an STC 60 assembly bravo
Thank you. It solved the noise problem for my client.
@@renovationtoperfection my conce n is the fire break between units , but other then that you can build sound studio walls for me anytime
So how did it turn out. Can you hear any noise?
Please, look 2 comments down. The client commented on the performance of the wall. Sorry, I see it 3 comments down, it is actually year old.
Please, look 3 comments down. The client shared the experience with the performance of the wall under the name NikkorDX.
@@renovationtoperfection I see thanks. Wonder if I could get your opinion? My wall looks almost identical to what you worked on. Im debating whether or not to tear the wall apart or not to put in Roswell safe and sound or not (strata might not give me approval).
How much of a difference do you think there would between:
a) Tearing the wall out and replacing the fibreglass insulation with Roswell, then putting Sonopan and another layer of drywall
and
b) Leaving the existing wall and putting the same Sonoran and lawyer of drywall.
Think it would make a huge difference between the two?
@@TheTCOLL Sonopan will not help you very much. The real life performance for noise reduction is not worth the effort.
You do not have to change the wall insulation, but if you will use two layers of drywall with the Green Glue in between on the resilient channels you will hear a difference.
On this project it was of utmost importance to eliminate all noise, that's why we went all in - ultimate soundproofing solution.
@@renovationtoperfection That is surprising that you think two layers of drywall will beat out one later of Sonoran and drywall.
Я не понимаю зачем между гипсокартоном клеем мазать? Это шпаклевкой делают. Какой смысл в клее? И почему пол дюйма гипсокартон а не 5/8 как положено по Коду?
Why not just do 2x 5/8" with green glue in between.
Because my clients wanted a Cadillac. The noise from new neighbors caused some health issues and we went all in to resolve it. Of course, you can go 2x5/8" .There is a variety of different drywall panels you can use successfully to improve the performance of the assembly, for us it was a matter of connection details in the corners.
You installed them upside down 😂😂
Pull those jeans up!
you installed the resilient channel upside down
Thank you David, this was already established in previous comments. I was, obviously, taught wrong to do it this way but I do not believe it has too much of an impact on the performance.
between you and your neigbourg there is just a dry wall??? lol
You made the biggest mistake by installing the bars upside down, it defeats the purpose of installing these as they will now be shouting on the studwork
Thank you for watching the video.
too bad you didnt show the step by step process of you actually doing the work , what a let down.
Sorry to hear. I thought this is actually step by step explanation of the whole process. You wanted to see me putting the batts of insulation into the framing and driving the drywall screws?
@@renovationtoperfection Yes, it would be great. You're really helping a lot. thanks! Can you tell me what size drywall screws you use and where must the end stop? Great video!
Hi there. I am using 1 1/4" drywall screws for the first layer of drywall and 1 5/8" for the second layer. It is important to keep track of the location of the studs so the screw doesn't hit the stud through the resilient channel. That would negate the sound dampening effect of it. I do not understand what you mean by ends. Feel free to reach out to me directly, I will be happy to advise you further. renovationtoperfection@gmail.com
