Thanks for the tips. I'll check with Isodrän to see what they say.
It wasn't an option to insulate on the top side because the garage roof is a deck floor. Insulation would increase the height and since there are doors leading out, that would naturally cause problems.
I read today that it is possible to spray EPS concrete with a screed pump on the wall and ceiling:

Here is an example:
The advantage of EPS is that it is diffusion-open. Spraying means that there are no requirements for substrate evenness, and it also insulates well and has a low weight. This solution currently feels like the most optimal and least labor-intensive, and it resembles the original construction the most but with more modern materials. Then one could mount panels on the underside. It seems like rebar should be anchored in the structural concrete to avoid the EPS falling down in the future...
Additionally, the net can be used as a benchmark when spraying so that you get a reasonably even underside.
The only problem seems to be how to get hold of a screed pump to be able to get the EPS up on the ceiling...
Anyone have any tips?
Interesting in this context is that träullit is based on wood chips impregnated in concrete. Despite the organic material, träullit seems to be very resistant to mold, etc. EPS is essentially the same type of material, just that the wood chips have been replaced with polystyrene balls, just a reflection.

You could hire the guy in the movie. You don't have to do everything yourself. What costs time is the demolition.G gomer said:

I think there will be problems with condensation on the garage roof if it is not insulated. I have seen tendencies towards this near the garage door (where there is air intake) with a cold concrete slab and humid air in the spring. This was with the old träullitisoleringen, so running completely without it probably worsens the problem significantly.
