ᐅ Installing fall protection anchored in the window reveal with external wall insulation (EWI)

Hello everyone, before I discuss this topic with the window installers, architects, and energy consultants tomorrow, I wanted to bring it up here and see if anyone has any advice.
We will start installing the windows tomorrow, and the issue of fall protection is becoming urgent. Ultimately, we need a few fall protection systems. For aesthetic reasons, we would like to attach the fall protection inside the window reveal. Our wall construction is as follows: 17.5 cm (7 inches) calcium silicate brick + 12 cm (5 inches) insulation; PVC windows with textile screens and guide rails. As I see it, the fall protection can only be mounted in the insulation layer. Without special brackets or similar mounting fittings—like those from manufacturers such as Schöck or Sto—attachment is not possible. However, these are quite expensive, especially when you need four per window.
I have considered installing four sturdy metal brackets into the wall per window and then applying the insulation in front of them. The fall protection could then be attached to these brackets. If this is feasible, the question arises whether the part of the bracket that is not insulated (where the fall protection is attached) would create a thermal bridge. This part will get cold, and the steel could conduct cold into the brick. Should the brackets be thermally separated? Do such solutions exist? Or is there any way to use standard brackets and somehow decouple them from the masonry?
I hope I was able to explain the problem clearly.
Best regards,
Ben

Sometimes a temporary solution is enough for testing.Of course, one could initially design a solution focused on energy-saving regulations and then switch to a version that complies with the building inspector’s requirements. However, the inspector will only approve the latter.borderpuschl schrieb:

borderpuschl26 Oct 2020 13:17Since the windows and the roller shutter guide rail are installed within the reveal, it is possible—depending on the wall construction and thickness—to anchor them into the solid material.
Yes, these options are also available from Roma. However, only for venetian blinds and only in combination with a glass fall protection system. This is not possible with Extil screens, and a glass fall protection system is not our first choice either.
I am still waiting for solution proposals from the thermal insulation consultant and/or architect.
