ᐅ Fixed glazing in uPVC windows leaking

Hello everyone

This concerns a solid construction house built in 2018/19, where I have PVC windows.
One of them is a two-sided casement window, connected at the bottom to a fixed glazing panel running the entire length.
So, at the bottom there is floor-to-ceiling fixed glazing about 2m (6.5 ft) wide and above that, two casement windows measuring 1 x 1m (3.3 x 3.3 ft) each.
By chance, I just noticed that the fixed glazing seems to be leaking, and as if that weren’t odd enough, it is at a very unusual spot.
The lower frame consists of two parts, so there is a "plastic joint," a seam or connection between these two parts.
And moisture is coming from there, with some brownish discoloration visible as well.
I’ve attached a photo.
Now, the actual question:
How can this happen?
It’s currently dark outside and raining, so I can’t check whether there are drainage caps or similar. But that’s unlikely on fixed glazing, right?
I hope you have a good tip for me.
It seems that hardly anything underneath the laminate flooring has become damp, but of course, I want to fix the cause as quickly as possible...

Best regards
Enrico

Please provide one photo each from the outside and inside showing the entire window along with the adjacent wall/reveal, lintel, and windowsill.

As long as the drainage on the OUTSIDE of the frame profile is not sealed, no water can come through the glazing bead joint.

Photos will follow, but I can only manage that by Friday afternoon.
By the way, the humidity level is 29%.

29% and no health issues so far

Sorry, but I have never seen such a reading with moisture problems and the current weather.

Hello, just a quick note to the group.
Regarding the water drainage, it is probably related to the rebate drainage, especially since the pictures are not very clear.
What can be seen is a triple-glazed insulating glass unit with a black spacer edge.
A glazing bead with an injected EPDM seal.
It would be helpful to know which profile system is being used so we can go into more detail.

So, are the setting blocks properly installed, are enough drainage channels milled in, and are ventilation grooves milled at the top of the outer frame? (For windows with RAL 7016, this is specified in the installation guidelines.) There are many potential points of failure, so GOOD PICTURES are important.

Best regards,
Thorben Müller

The arrogance and tone some people use here is truly unbelievable.
Who do you think you are?!
