Air conditioning: Guide refrigerant pipes and co through the vapor barrier

Hello everyone,

I hope you can help me; unfortunately, I couldn't find anything that specifically answers my question.

It concerns the installation of a multisplit air conditioning system in a single-family house from 2016.
For this, 6 refrigerant pipes, 3 power cables, and condensate lines are to be routed from the outdoor unit first through the exterior wall into the upper floor (ETICS, hollow brick) and from there onto the cold roof, and then branch off into the individual rooms.

To do this, the membrane (vapor barrier?) beneath the insulation on the cold roof would have to be damaged.

For the individual cables and lines, I have found such sleeves, but considering the bundle of 6 pipes plus cables and so on, I wonder how to create the penetration and seal it again.
Does anyone have a tip for this?

Is it sufficient to foam the remaining cavities with well foam when passing through the exterior wall into the upper floor and to plaster from the outside?
This seems to be a common method...

Thanks in advance for your advice

These cuffs are available in all sizes and variants, including for DN100. But it also works with the system adhesive tapes.

The frequency of the application of well foam does not make it more suitable for this purpose! "We have always done it this way" is also not an argument.

Tube bundles as well as cable bundles are to be avoided so that you can seal each tube/cable all around with a separate sleeve or system adhesive tape. In an otherwise very tight house, just a pinhole-sized hole easily transports about 1/2 liter of water (per hour!) naturally dissolved in the air.
