ᐅ One more question about windows

Hello

Warranty work is due for our apartment. We have reported all the defects we noticed to the architect.
Among other issues, there are drafts/leaks of about 10cm (4 inches) between the window frame and the masonry (I hope you understand what I mean). Additionally, there are drafts in the areas where the crank for the roller shutter was drilled through the frame, that is, through the metal covering.
The architect(s) have now confirmed the appointment to fix the defects, but they refuse to address these two specific issues. Their reasons are:
- No guarantee for airtightness because it is not built to Minergie standard (according to SIA xy)
- Cranks were installed properly.

Can anyone advise how I can still get properly sealed windows? Or which leaks must be accepted?

Thank you very much

The Swiss construction industry aligns its execution with EU standards. The applicable standards in Switzerland are "SIA 331 Windows and Window Doors" (which also regulates connections and thermal insulation) and "SIA 118/331 General Conditions for Windows and Window Doors – Contract Conditions for Standard SIA 331:2008" (which also covers construction execution and defects).

Your architect cannot simply allow windows to be poorly installed in the wall and then dismiss it by saying "It’s not Minergie standard." Refer to SIA 331 and 118/331 and insist that they comply with these standards; ideally, they should bring the relevant text from the standards to a meeting to explain the installation details. Leaks must not be accepted.

This is a clear case and we have experienced the same. It is unacceptable that the architect claims the windows do not need to be sealed. I gave the architect a deadline to fix the defects, or I would take legal action. In any case, he was cooperative and corrected the issue. Such poor workmanship must not be tolerated.

This is clearly poor workmanship. Gaps of 10cm (4 inches) like this cannot be true. They even have the audacity to claim that these are not defects. It’s basically a case of audacity wins.

In this case, I can only shake my head. It is unbelievable that the client has to accept such poor workmanship. This is a matter for the court.

Or rather, which leaks must be accepted?

There is no room for tolerance in this matter, as I want windows that are fully airtight, period. Standards still exist and must be followed. If this has not been achieved, corrections must be made.
