ᐅ How to Install Fall Protection in a Window Reveal

Hello,
unfortunately, there were many planning inconsistencies with our floor-to-ceiling windows, so almost everything had to be changed.
Now, the windows are supposed to be installed flush with the exterior wall surface. It was agreed to install fall protection mounted on the inside of the window reveal.
This means, however, that it can only be anchored laterally in the external wall insulation system (EWIS / EIFS) and no longer in the masonry. Is this a common practice?
In most places, there will be a metal grille; on two windows, a glass pane is planned, which I think will be significantly heavier.
I also would not rule out that children might stand on the lower bar of the grille when the window is open.

Can someone tell me how this is usually done?

There is nothing to anchor in the insulation layer. The anchors must be fixed in the masonry and, if necessary, installed (also in terms of timing) before the windows. The planner will need to use some creativity here.

You are overlooking a significant load case, namely a person falling against it.

Then the grille is not a fall protection — unless the grille extends 90cm (35 inches) above the top edge of the second highest bar.

Haven’t we already discussed this topic a long time ago?

Unfortunately, my confidence is slowly starting to wane here. Can I imagine the anchor as a kind of extension plate that is anchored in the masonry and then extends into the external thermal insulation composite system (ETICS) to hold the railing?

True, I was thinking more of everyday use.

I was referring more to the framing. It’s clear this isn’t supposed to be a ladder.

Hmm… I don’t remember. But I can’t rule out that a lack of sleep at night is starting to show its effects.

Best regards

I honestly can’t imagine what your planner might have come up with: I’m neither familiar with your project fragmented across numerous threads nor able to read the planner’s mind. How the fixing is done (drilled through, embedded, angled, offset, etc.) is a matter for an engineer you pay for. You shouldn’t leave this to the contractors to figure out—neither based on their own judgment nor on experience gathered by collective guesswork.

We had a similar situation; try searching for Dosteba load-bearing brackets, for example. This way, you get an anchoring point in the insulated facade system (EIFS) at the window reveal. But be careful, these items are not exactly cheap. We installed 4 pieces on each of 2 windows, but it’s money well spent for safety!

Now the windows are supposed to be installed flush with the outside surface of the wall. It has been agreed that a fall protection device will be installed on the inside of the window reveal.

How is that supposed to work?

The windows should be flush on the outside, and then the fall protection inside the reveal?
