Spiral duct in wall

[empame]

I will need to install some conduit in an interior wall. My plan is to build a wall with 45x120 timber and fit a 100mm or a slightly flattened 125mm conduit. Can I cut the vertical studs and place the conduit there and then cover it with boards? It will be both OSB and plasterboard. Do you think the wall will become unstable if done this way? The alternative is to drill 110mm holes in the studs and insert a 100mm conduit...

If it is a longer distance, I think there is a risk that it might become a bit unstable. There are rectangular ducts that are significantly easier to embed in a wall. These are (to my knowledge) made of plastic, so they only work if intended for ventilation, not for a kitchen fan.

Yes, it is pretty much through the entire wall... Rectangular ducts did sound interesting, it is exhaust air from a bathroom.

You cannot cut all the studs in a wall, especially in a wet room wall. Can you not run the pipe up into the joist space?

Where does the channel go?
If it is a duct from the kitchen fan, you need to add fire insulation or have a few centimeters of air around the channel.
This will not fit inside a wall.

It is exhaust air from the bathroom upstairs. No, I will not pull on the wall. Either visibly in the closet which is next to it or I will simply cut the plastic and push it up into the ceiling.

can you make the wall with horizontal studs?

If it's not a problem going through the plastic, I would do it. I've done it in several places in my house. You buy a pipe collar to seal between the pipe and the plastic. I bought my collars here; it's the cheapest I've found. Make sure you choose the right size.

I think it feels cumbersome to start with square pipes or build a wall with horizontal studs.

Damn, that's serious with the collars. I usually seal my penetrations with tape (the proper kind for diff barriers). But something like that will do, then I'll also have the valve on the ceiling instead of on the wall.
