Scrape off old EPS facade insulation

What is actually the background of the renovation? If it were about improving the insulation, one could also double up

I wouldn't do anything either, but as writes, simply put the next layer of insulation on. Simple, efficient, and inexpensive.

Yeah, thanks, that wasn’t asked. The VHF is in progress.

How will the VHF be structured?

Cross battens made of wood, wood fiber in between, fiber cement on top.

For the approximately 2 m2, I took about 2 hours yesterday. Tool of choice - a mini hoe from the hardware store. I was also able to separate EPS from the plaster relatively cleanly with it (I don’t even know if I have to do that here in CH, I think everything is rather burned). Most of the time is spent on the separation, and it must not be windy, otherwise EPS quickly flies around. What worries me, however, is that EPS was apparently glued to the facade with cement - see gray plugs. I can’t get them off without breaking the bricks. Question - is it then a thermal bridge with the new facade because you can’t get the wood fiber (Gutex Thermo) evenly attached, or can it be ignored?
