Everything seems simple after it's understood. I sought the answer to this question on many forums and did not once stumble upon this great solution with the rubber, insulation, and fabric. Thanks as always for the top-notch content!

Thank JH Brandt. I got the idea from him. Rod likes to connect his doors but I like Brandts technique better.

Thanks for the video. How do you deal with condensation between the widows?

[@soundproofyourstudio]

I don’t have any issues with it, but you can add desiccant packets under the insulation.

[@DavidFloegelDrums]

Super interesting! On your doors, do you have one continuous strip of rubber that goes around? Or is it multiple pieces?

[@soundproofyourstudio]

It can be multiple pieces but ideally three strips. Everything must still be air tight so acoustic sealant is needed.

[@DmanW123]

Do you have a link to an example of the type of rubber you mentioned? Curious about thickness, or if there is a type of rubber in particular to look for.

[@soundproofyourstudio]

I use 1/16” rubber from amazon

Rubber is the same as neoprene?

I have 2 sliding glass exterior patio doors which was meant for a condo on street side. both are double pain and have air tight seal. Im doing the double wall air gap wall so im wondering if i should have two sliding glass doors or is that overkill?

[@srtswpak47]

My understanding is a single sliding door is going to be a weak spot and you would get more isolation with two separate sliding doors. How much it matters to you that sound would get in or out of a single sliding door is up to regarding if it's overkill or not. I would definitely do two sets of sliding doors in your situation.

[@soundproofyourstudio]

It not overkill and may not be enough isolation depending on the type and thickness of the glass

I’m wondering, is the rubber really necessary? Because if you just filled the gap with cheap acoustic foam cut to size nice and snug, wouldnt you actually benifit from there not being a solid structure in the gap. Resonances between the doors or between the glass would actually have somewhere to go “inside the wall” which is filled with insulation. So I almost feel like leaving out the rubber would make it so you don’t even need to add mineral wool and all that. Would love to hear your thoughts. Thanks for the info!

[@soundproofyourstudio]

I think there is a concern for smells from the cavity. You really can do what levers you like as long as the walls are not bridged with something solid that easily conducts sound.

@@soundproofyourstudio that makes sense!

As a non american, I didn't understand the represntative figures. It's could be useful to shoot examples in the work site, so we can see what's your talking about and how it's done, but big thanks for the explanations ❤️

[@soundproofyourstudio]

Next time I have a Nashville project I will shoot some video.

What happen if half of this system touches the house structure

[@X0mb13]

Hey Wilson - you may have covered this already, but if you did, I missed it - In a scenario where the studio space is an attached part of the home, what do you do about the forced coupling caused by a continuous floor or ceiling? I assume that the ceiling and floor connecting one room to the next is a necessary evil? Unfortunately, fire code isn't going to allow an air gap that completely separates the studio from the rest of a structure due to a large air path going from the basement/crawlspace straight up through the attic.

[@soundproofyourstudio]

What about putting in fire stops in that airgap?

[@X0mb13]

@@soundproofyourstudio Right, but wouldn't that just end up causing coupling again?
