Facade insulation, effects on windows, roller shutter box and attachments

Do you perhaps know a site where all of this is explained in detail?
You mean that the reveal of the old window opening, i.e. the old masonry, is externally insulated? That would have to be done with the same thickness, for example 15cm each. Then the windows must become smaller - or rather the window opening has to be enlarged, because otherwise the roller shutters will no longer fit.

That is a completely normal procedure, even in new construction external insulation is applied. Attached is the first image that appears after two seconds of searching on Google. The reveal is insulated on the inside and outside or the frame is insulated (or the guide rail of the roller shutter). The new window sill adapts to this.



And in reality it looks like this on the outside (as at my home as well):




For the reveal there are even special reveal panels. Normally it is two to three cm of insulation. That is also completely sufficient. State of the art.

You mean internal insulation? That would be my favorite, because I could do that myself, but that would cost too much living space. Or do you mean removing and reinstalling the windows from the inside? But that does not change anything about the sketched problem of external insulation.

Internal insulation of the reveal. See picture above. As I said, there is no problem with external insulation.
Complete internal insulation is usually rubbish and often leads to mold. For a layman it might even be more difficult than doing ETICS oneself.

In new buildings, the windows are set "normally" far outwards from the start.
But well, it is certainly also a question of the width of the windows.

Just as it makes sense. For example, monolithic buildings not quite to the outside, because then you no longer have a window sill. With ETICS outwards or into the beginning of the insulation layer.

That looks "normal." ;-)

I’m telling you... windows are about 1.5cm smaller on each side than the old building windows. Moving forward would have involved a lot of effort since they sit on the masonry outside and then there is the facing brick which also sits in front of the roller shutter box. As in the picture. Lintel above the roller shutter box, brick outside in front of the roller shutter box. New windows then ordered with top-mounted roller shutters, installed identical to the old stock and insulated as described above.

In new buildings, the windows are from the start set "normally" far outward.

Ours are about centered. That leaves space on the outside for a box-type roller shutter and inside there is insulation behind the profile. Everything is plastered over so you can't see any of it.

That's why I'm asking - precisely because it seems to affect every second person.

What I wanted to say is... talk to a specialist about it. The energy consultant knows the cases and can tell you what is the most sensible option for your exact construction and renovation method. You generally need them anyway for funding. And the window manufacturer certainly knows the problem too.

Year of construction 1992, is external insulation actually somewhat reasonable for you? Serious question, it varies from case to case.
