Multi-purpose Music/Home Theater/Recording Studio

Thanks. Regarding my 2 layers that I put on the Enermax (OSB + gwb), someone told me that I could first put a horizontal wooden slat. This would create an air space between the vapor barrier layer of the Enermax and the OSB in order to prevent condensation and the risk of rot. I read that OSB can act as a vapor barrier. So moisture could be trapped between the Enermax and the OSB (dew point). However, if the humidity level in the studio does not exceed 50% and everything is well sealed, the risks are minimal.

Is this a good idea (the slats) and would it not reduce the soundproofing?

as long as your vapour barrier is properly placed and sealed, then no, you don't need the slats and in fact could cause issues between the two layers as there is now an air gap - think 3rd leaf type issues.

On the acoustic clips, since there's no supplier in my town, I bought a pack of rubber puck and made a demo to show you how I would use it and if this could be acting the same as the clips.

diameter: 3.75 inches
thickness: 0.5 inch

Is it something that could work (to reduce sound transmission from the studio to the gym) ?

only if the bolt is decoupled from the frame as well. check out the Kinetics Noise Wallmat - see the type of bolt decoupling.

Thanks a lot Glenn. I think I've come up with a pretty good solution. You'll be able to confirm this (I hope) when I start my studio building thread soon.

I apologize for revisiting my previous question about condensation in the wall. I am not questioning your expertise in any way, but since a mistake at this level could have serious consequences, let me double-check with you.

I am in Quebec and we have a very long and often very cold winter. The building code standards here recommend having an air space after the vapor barrier. This is also what a building architecture technician confirmed to me. However, I think that just because a solution does not fit into the standard does not automatically mean it is bad. And the building code does not recommend sealing the layers as you would for a studio...

Can the surface temperature of the Enermax drop below 12 degrees Celsius and create condensation with the air coming from inside? (should I test it with a surface temperature detector?). When i put my hand on the Enermax it's cold but i can't tell what the temperature is...

So if you could review how my current walls are made and reconfirm your recommendation that would be greatly appreciated.

The simple answer is, build in accordance to code. So if you need a value barrier on the inside to prevent indoor moisture condensing into the insulation, that would be good.
