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

There are different systems and options available. Angles and panels. Decoupled and non-decoupled.

Really? Great. What should I search for, or do you have any example for me? The only thing I found were these mounting brackets for insulation, and of course, at €200 each, that’s not a viable option.

Best regards

I have not researched the prices for such items in GRP, but I just want to briefly point out that "stable" does not necessarily mean "steel."

Yes, that's true. But if I now, for example, search for fiberglass reinforced plastic (FRP) angles or similar, I still can't find anything suitable...

First, do it the way you want, then let the inspector come. Then you will see if you need to make any changes or not. Sometimes a temporary solution is sufficient for the inspection. It is usually a matter of liability, not feasibility.
