ᐅ Window Installation in External Thermal Insulation Composite Systems (ETICS) – When Can the Window Installer Take Measurements?

Hello forum,
We are currently in the process of having a house built.
The shell is up, and the brick cladding is almost finished.
The house is built with sand-lime bricks, and in the upper third an external thermal insulation composite system (ETICS) with plaster will be applied, while the lower two-thirds are brick-clad.
I was told that the window installer can only take measurements once the brick cladding is completely finished.
Does the insulation and plaster on the upper section also need to be completed first, or can the windows be measured and installed beforehand?

Which measurement the window manufacturer needs to take—so, exactly where to measure—of course depends on the installation plane of the windows.
But your question was when. And the answer is clear: this can be done now. So measure, produce, and deliver—installation can be coordinated later with the external thermal insulation system (ETICS) installers if necessary.
I understood your words as meaning that all the lower windows would have to fit with the cladding, and that most of the lower windows only need to fit with the ETICS. However, the drawing shows that all the upper windows—not just those extending below the "standard" sill height, as I thought—are also located in wall sections affected by the cladding.
That was only a minor misunderstanding, without any practical implications.
I will clarify the relationships again, regardless of the exact installation plane: the need to measure at all is related to tolerances between the planned dimensions and the actual execution. In this sense, you can only measure what physically exists. So far, this applies only to the structural wall shell and the cladding wall shell.
This is sufficient, which simply comes down to the hierarchy: the wall takes precedence over the window—you better know the final ordering dimensions of the window later than having to chip away stones later, whether masonry or cladding bricks. But the window takes precedence over the ETICS: the insulation boards are easily cut to a slightly different size (and are only brought to their exact size at installation, where they are the last board in their row). Therefore, the window does not have to conform to the "wall" here and can already be present at this point. Whether it should already be installed is best coordinated with the contractors regarding the sequence.
For the lower windows, with the finished cladding, everything is fixed. For the upper ones, I thought they only needed to fit with the ETICS. In that case, where the actual dimension of the structural wall shell does not contradict, I would have manufactured them according to the dimensions of their counterparts on the ground floor. But since cladding is also present in the area of the upper windows, individual measurement applies on the upper floor as well. This is the only difference arising from our misunderstanding.
Since the entire upper floor height is not covered by ETICS here, I assume installation will be on the outer line of the structural wall shell. As soon as you can replace this assumption with case-specific knowledge, the windows on the ground floor can be installed as well. The upper floor windows can then be installed when the ETICS team says they prefer them to be set and ready.

And who pays for the window installers’ double trip? If – which I don’t expect, but it’s better to ask just in case – the external wall insulation installers prefer the order reversed, their overtime could cost more than one trip by the window installers.
