How to install fall protection in window reveals

Hello,
unfortunately, there were a lot of planning inconsistencies with our floor-to-ceiling windows, so basically everything had to be changed.
Now the windows are supposed to be installed flush with the outside of the wall. It has been agreed that a fall protection will be mounted on the inside of the window reveal.
However, this means that the fall protection can only be anchored laterally in the insulation system (WDVS) and no longer in the masonry. Is this generally common practice?
In most places there will be a metal grille, at 2 windows a glass pane, here I think significantly more weight is to be expected.
I would also not rule out that children might stand on the lower bar of the grille with the window open.

Can someone tell me how this is usually done?

There is nothing to anchor in the insulation shell. The anchors must be installed in the masonry and, if necessary (also in advance) before the windows. The planner will have to use his brains here.

In most places there will be a metal grid; on 2 windows a glass pane, which I think will be significantly heavier.

You are not considering one essential load case, namely that of a person falling against it.

I also would not rule out that children might stand on the lower bar of the grid when the window is open.

Then the grid is not a fall protection – unless the grid is still 90 cm high above the top edge of the second highest bar.

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

There is nothing to anchor in the insulation shell. The anchors must be installed in the masonry and possibly (also in terms of timing) before the windows. The planner will have to use his brain for that.

Unfortunately, my trust is gradually fading here. Can I imagine the anchor as a kind of extension plate that is anchored in the masonry and then extends into the ETICS to hold the railing?

You are neglecting a significant load, namely that of the person falling against it.

True, I was rather thinking of the daily use.

I meant more the frame. It’s already clear that it is not supposed to become a ladder.

Hmm... I don’t remember. But I also can’t rule out that the sleep deprivation at night is slowly taking its toll.

Best regards

My trust is unfortunately gradually diminishing here. Can I imagine the anchor as a kind of extension plate that is anchored in the masonry and then accordingly extends into the ETICS to hold the railing?

I cannot imagine anything that your planner might come up with: I neither know your project scattered over numerous threads nor can I read the planner’s mind. How it is anchored here (drilled through, inserted, angled, bent, ...) is a question that a paid engineer has to deal with. You cannot leave that to the executors, neither in their own minds nor with experience borrowed from a collective intelligence.

we had the same scenario, try searching for Dosteba angle brackets for example. Then you have an anchor point in the ETICS in the window reveal. But be careful, these things are not exactly cheap, we used 4 pieces on 2 windows each, but it's money well spent for safety!

Now the windows are to be installed flush with the outside of the wall. An anti-fall protection installed on the inside of the window reveal has been agreed upon.

How is that supposed to work?

The windows are to be flush on the outside and then the anti-fall protection inside in the reveal?
