Hi,
so, you build a double leaf wall, add adequate sound proof window and doors and then you need to route cable through the wall ...
But how?
Ok, it's possible to cut holes in the gypsum wall leafs, put a multicore through them an caulk the holes air tight again.
But you never can add another cable ... Need firewird: to late. Need Glasfiber: to late. (or you has to open the wall again ...)
Are there any other solutions? Some kind of sound proof cable channels?

Re: Cables through walls
Conduit! Basically, PVC "pipes" that are big enough to run all your existing cables, plus all possible future cables. Either one large conduit, or several small conduits. You could even leave some of them empty for now, available for future expansion.
The trick is to seal them and decouple them! With or without cables, you do not want them to create a mechanical flanking path between rooms, and you also do not want them to be an open tube between rooms. so you need to prevent them from having any kind of solid contact with the structures, and you need to plug them tightly at both ends, sealed airtight, to prevent sound traveling down them.
And do yourself a huge favor: leave some "fish-tape" or "leader" running through them (or whatever it is called in your part of the world): Basically, some kind of tough semi-flexible "thing" that you can attach future cables to at one end, then use to pull those cables through the pipes to the other end. It is really hard to try to "push" cables through conduit: you can only "pull" them.

Re: Cables through walls
Weed eater plastic twine refills are good for leaving in place for future cable pulls.

good suggestion - the tongue used in T&G flooring is another good pullthrough. The yellow in this pic.rehkram wrote:Weed eater plastic twine refills are good for leaving in place for future cable pulls.

Use some Polyline or "pull string"

Re: Cables through walls
great idea on the "leader" to pull new cable in the future. great! on sealing up the conduit, i was going to stuff it with rockwool, tight, and then "cap" it with caulk on each end. sound good?Soundman2020 wrote:Conduit!
