If you install a duct in the intermediate floor that is less than or equal to 125mm, you can fit some kind of clamps and hangers. 125+30+30=185mm
But, how do you do it if you want to install a 160mm spiro? 160+30+30 = 220, it fits, but how do you do it practically?
I don't want to lay the pipe on the insulation, as the weight of the pipe and its own weight should compromise its function (get compressed).
Has anyone done this?
Or should I settle for 125?
(Please don't choose the easy answer now
)
PS.
Or is there some kind of pipe support that you can place underneath? E.g., on a piece of batten?

I probably manage to ask questions that are too difficult (that not many people know or are interested in answering), or too simple ("I can't be bothered to answer such a simple question").
So I hereby use my bump on this thread...

It sounds like you're looking for a bit of a kanalstöd, but assuming you have enough insulation around the duct from a fire safety perspective, I can't say how the kanalstöd affects the whole thing.
In your case, I would probably guess that fire safety would be the limiting factor for how large a duct you can install. www.imkanal.se is usually my recommendation for reading.

Yes exactly, duct support, but the ones I've seen are so high.
If you have a floor structure of 45x220 timber, then a 160mm duct is the max, as 160+30 mm insulation becomes exactly 220mm.
So, if the duct support, like the one you linked to, was 30mm instead of 120, it would work.
The alternative as I see it is to make a minerit or gypsum box in the floor structure, but matte still feels a bit better...
Otherwise, maybe a sheet metal company could quite easily make 3 supports for me at 30mm height. It's not such a long stretch it concerns.

The "kanalstöd" that myrstack linked to can be easily adjusted in height by cutting it down.
