Idea for Running Conduit Between Rooms

I have been trying to figure out what would be a good way for me to be able to run my conduit through the gap between the control room wall and the live room wall. I have a 5" gap and am thinking about building a platform in the space to suspend the conduit, which will be glued to the floor and caulked to the adjoining floor boards to give it stability, but keeping it decoupled as well. Then running the conduit just shy of the sheet rock and fill that gap with acoustic caulking as well. Let me know if I am on the right track, or if someone has done something like this previously? Thanks guys :D Sorry about the small text

Take a look at Aaronw's build. You might find some of your answers there.

Thanks, I've seen his build before, ide love to be able to run my cables under the floor but unfortunately im unable to.

I wonder if you could cut out a 20cm section from the pipe run and replace it with a thin doughnut of sonex or similar cable tied in place. That would stop any vibrations running down the PVC? The rest look good :)

Neat idea, Lil! Gotta add that to my design! :) Thanks! - Stuart -

:? Im confused by what you mean Lil, can you explain it to me a bit more? :)

I think this is what Lil has in mind:

Rough idea, of course. Just cut the pipe to decouple the two ends, then stick some kind of a "donut" of acoustic material in the gap to maintain continuity of the pipe (so you can still pull cables through it!). I'm thinking that even a strip of soft rubber, neoprene etc. rolled up into a pipe-shape (the way you roll a carpet), and cable-tied at both ends should do the trick. Maybe instead of cable ties, you would just use good old fashioned (gasp!) duct tape to keep the rubber section in place. It would have to be longer than I show in that diagram, of course. Lots of options. Is that what you had in mind, Lil? - Stuart -

More like this, I think:

hmmmm, so there are two pieces of pvc held by the sonnox together? and would the break be where the conduit would be entering the drywall/room/leaf?

no it could be anywhere between the 2 rooms. But some deadening at the point it passes through the wall is prob a good idea too :D

so the 2 pieces would basically be connected by a rigid rolled up piece of sonnox, between the two rooms, which would decouple the shared conduit run for the rooms themselves, is that correct? :D What kind of sonnox would be used?

What kind of sonnox would be used?

I reckon pretty much anything would work. It only has to serve two basic purposes: decouple the pipe, but still provide an path and guide for cables. That's why I think that rubber or neoprene might be better. And instead of cable ties / duct tape, I'm thinking that hose clamps would work much better. - Stuart -

When I ran conduit between the two tracking rooms, I had to do the same thing. I just created a break about 1/2" space roughly (maybe less) and covered the gap with duct tape mostly to keep bugs from ever getting in there (god forbid I ever have that problem). But it worked just fine. As far as poking through the wall, mine comes just shy of the front layer. The hole is slightly bigger so I could get a good seal with acoustic caulk but also reduce it from touching the wall structure.
