ᐅ How to Insulate a Basement and Garage Ceiling with a Thin Layer – Which Materials to Use?

ralallaI would like to gather some preliminary information about what I could do to my house (basement, garage). I have an architect who advises me, but they are currently on vacation, and I want to collect theoretical information before the renovation starts (renewing the electrical system, etc.).
The house was built in 1956 and has an attached garage. Access to the basement is from the hallway (wooden door, or standard interior door) via a staircase. The entire staircase structure is made of wood, enclosed on the basement side, and is in very good condition; it should be preserved. The basement height is about 2 meters (6.6 feet). The clearance height at the doorways to the individual rooms is about 1.90 meters (6.2 feet). I would like to insulate the basement ceiling as well as the wooden staircase structure from below, that is, from the basement side. All utility lines will be renewed; I will run them along the walls, keeping a distance from the ceiling. However, the insulation should not be so thick that I constantly hit my head—I am 1.89 meters (6.2 feet) tall.
What kind of material (or maybe someone could even name a manufacturer and type) can or should I use for insulation? The basement ceiling is not necessarily flat.
There is also the issue of the garage. It can only be accessed from the outside. Previously, the garage roof was used as a balcony, but at some point, about two-thirds of it was converted into an extension, with a door leading to the remaining third, which is still used as a balcony.
The garage ceiling is only about 1.80 meters (5.9 feet) high, with double T-beams running along it, under which the clearance height is estimated to be only about 1.70 meters (5.6 feet). If I only insulate between the beams, would there be a risk of condensation on the steel beams? If possible, I would like to keep the 1.70 meter (5.6 feet) height since the car still fits in that space.
The temperature in the garage will be almost the same as outside, as the door is an old wooden door with a lot of air leakage.

Hello,
Mineral wool boards might be a good option here --> Isover
However: individual measures are also supported by KfW. They also specify minimum thicknesses.......
When was that done? It must have complied with some thermal insulation regulations at that time.
Best regards

Also the garage problem. It can only be accessed from the outside. Previously, the garage roof was used as a balcony, but it was partially converted into an extension covering about two-thirds, with a door leading to the remaining third, which is still used as a balcony.

I have already used the total budget (50,000€) for my roof insulation, the new heating system, the front door, and a window, so I no longer need to comply with any minimum thickness requirements for the basement. However, I still want to do something and am not very familiar with the materials to be used, so I’m unsure what would be suitable. Your example was a good starting point.
The extension was built a long time ago, before thermal insulation regulations, probably around 1965–1970.
