ᐅ French balconies on 17 cm Ytong blocks with 12 cm insulation?

Hello everyone,
We are building with 17cm Ytong blocks (7 inches) and 12cm insulation (5 inches) to meet the KfW55 standard. For the planned floor-to-ceiling windows, we have been offered (expensive!) steel brackets mounted on the outside of the house wall, to which the French balconies / fall protection will be attached.
- Isn’t there a more affordable and aesthetically pleasing solution? Do you have any ideas? Links are welcome ;-).
The alternative would be to use windows with a fixed lower part 🙄
Thank you very much and best regards from Stuttgart!

I’m more experienced in awnings and sun protection, and with Ytong I always go completely through the wall. You can’t fix anything with just anchors there. There are very effective thermal break mounting systems available. And if an awning holds, your parapet will be rock solid as well.

It just doesn’t look nearly as nice as floor-to-ceiling windows with a French balcony.Exactly! Not just nicer, but much nicer. I really don’t understand why grilles or panels used as a balustrade in front of floor-to-ceiling windows are supposed to look better than floor-to-ceiling windows that have a horizontal frame either in the middle or at about 80cm (31.5 inches) height. And if costs are already making things difficult, I wouldn’t hesitate for a second to avoid mechanical damage to the external thermal insulation composite system (ETICS) and the render.

Because on the other side, I don’t want to give up floor-to-ceiling windows.Floor-to-ceiling windows on the upper floor are already out of fashion. Regular windows, preferably wider, provide more usable wall space, don’t require privacy screens, are more cost-effective, and look more balanced from the outside.T

Check if your roller shutter manufacturer offers fall protection systems made of glass. They can integrate them, usually installed below the guide rail, so your wall remains untouched... Good idea, I’ll ask — thank you!

I honestly don’t understand why grids or panels as balustrades in front of floor-to-ceiling windows are supposed to look better than floor-to-ceiling windows that have a horizontal frame either in the middle or at about 80cm (31 inches) height. And if the costs are going to be difficult anyway, I wouldn’t hesitate for a second to skip mechanical protections on ETICS (external thermal insulation composite systems) and render. … in the end, it’s probably a matter of personal taste :-)
Currently, in our rental apartment, we have floor-to-ceiling windows with a French balcony, and we find it quite nice. It’s also convenient that we can open them fully.
But of course, costs will be an issue in any case – fall protection with steel brackets underneath was briefly estimated at over €20,000, and we immediately said no way (especially since, as mentioned, this was *actually* supposed to be included in the price…).

thanksgiving13 Jul 2023 10:23For our project: We requested the price difference between a fixed base and a French balcony and will decide afterwards. I would probably use these Fischer anchors for the attachment, as they do not create a new thermal issue and are not a big financial burden (-> price comparison page).
