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!

Thank you. I am glad you enjoyed it.

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.

Hello Richard, thank you very much for your comment.

Sonopan actually helps very little in reducing the noise level through the wall. Definitely not worth the cost.

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.

Yes, you do need to finish the final layer of drywall so you can prime and paint the wall.

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.

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.

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.

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.

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.

It should make no difference if you overlap them properly for acoustical performance.

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.

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.

Sorry, I do not understand your question.

You can if you know the location of the studs.

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!

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

@@MultiCooldude777 Ottawa area. Check out Renovation to Perfection on Google! g.page/renovation-to-perfection?gm

LOL

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.

Yes, I am.

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.

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.

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.

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.

Yeah, I know. Thank you for watching.

I know. But the client wanted ultimate solution and requested this.

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

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.

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.

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.

Thank you for watching the video.

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
