Hello everyone,
I have plastic windows that are about two years old, and there is water and dirt accumulating between the glass and the frame. The window seller told me this is normal because the windows have a dry glazing system. My question is whether this is really normal? I have looked everywhere and have not seen similar dirt and water buildup inside any other windows so far.

The glazing putty was used back in the days of single-pane glass, which is a long time ago. Insulated glass units are also sealed with silicone—probably with foams that are often misused (and, “just to be safe,” usually overdosed) in construction. If these materials were suitable as an adhesive, it would make non-destructive replacement much more complicated and much less likely to succeed. The issue here is probably a combination of unclean manufacturing conditions and an inadequately sealed insulated glass unit. Apparently, even some window sellers are unaware that the space between the panes is not filled with breathing air.

Thank you for the quick response! What would you do if you were in my position?

Almost all plastic windows use dry glazing. It is not normal for that much water to get inside. The glass might be incorrectly installed. The water also looks more like condensation, which would mean that once water gets behind the seal, it cannot drain or evaporate within the frame.

I would carefully check whether the warranty period is still valid and have the insulated glass unit claimed and replaced,

The water hasn’t actually leaked in. It’s not that the insulated glass unit in the sash is installed incorrectly, but that it was not manufactured properly and is not sealed.

It is condensation, yes, but it didn’t get behind the seal; it formed from air that has penetrated into the insulated glass unit.
