Hello everyone,
we are now about to install the windows… As far as I know, the window reveal must always be filled before installation. This has been done everywhere, but as a layperson, I’m not sure if this is correct..? My site manager tends to agree with everything and so does not have much expertise (a request for a replacement has been made).
From the picture, it can be seen that this was done only with cement mortar.
The exterior wall structure is: 1cm (0.4 inches) plaster (interior), 17.5cm (7 inches) Poroton brick, 16.0cm (6.3 inches) insulation, 1.5cm (0.6 inches) plaster (exterior).
Friends who have recently built their homes say that a smoothing coat must still be applied. Is that true, or would this work as it is (see picture) to ensure airtightness?

This could have been done more neatly with filler putty instead of mortar (and/or with more care), but it will probably affect the following plasterer the most. The window installer will likely use angle brackets and position the window frames at the outer edge of the wall. Once they weigh in, we’ll know more – at the moment, I can only speculate about the installation level based on the described wall construction.

This could have been done more neatly using filler compound instead of mortar (and/or with more care), but it will probably be most relevant for the plasterer who comes after. The window installer will likely use brackets and set the window frames flush with the outer edge of the wall. If they chime in, we’ll know more—at the moment I can only guess the installation plane based on the stated wall construction. In your opinion, should I have this done properly or take it into my own hands, or will the windows still be airtight enough to pass a blower door test..?
Without knowing the installation level, it wouldn’t even be clear which area should be improved before someone continues working on it. The window installer has their own say and opinion about the requirements needed to do a proper job. From an abstract perspective, I don’t see any concerning issues here.

I would first ask the shell construction contractor if this is the final condition, and then check with the window installation company about the site preparations they require, and proceed accordingly. After all, they need to guarantee their installation later on. But you will likely get feedback on this no later than during the measurement appointment.
@11ant is of course right that it ultimately depends on the quality of the installation surface. In general, it would have cost the shell contractor only slightly more time and materials to apply a continuous smooth coat instead of patched repairs. Unless they are planning to do that anyway.

Probably not, as that does take a significant amount of time, and the plasterer will embed a mesh there. So, the condition "before plaster" is likely considered "finished" as is.
