What's wrong with my glazing?

[Dunc]

Bright sunny day today (for the first time in a while) and noticed what seems to be condensation or contamination between the panes. It's not on either touchable surface; it appears to be between the glass panes. Seems to be only in the large fixed pane which is ~2x2m; the opening pane beside it is fine. South facing if that makes any difference. Triple glazed, aluminium clad, installed 2025.

Any ideas what this is? Causes? Solutions?

The glazing units seal has failed, allowing moisture into the gaps.

 

Only fix for triple glazing is to replace the glazed units with new. As they are so new, you should be covered by the warranty, and these should be replaced FoC

Oww! Yes, definitely failed unit. I'm gloomy enough about one of mine failing in year 11 of a 10-year warranty 😞, but yes, you should be covered without question. Who installed them - you or the supplier?

Well that's disappointing to say the least. No end of trouble with these windows. I really wish we'd gone with another manufacturer.

 

Installed by their "recommended" installer, so not a direct link there. But at least we know I didn't mess it up. Will have to check the warranty to find out who's paying for the labour.

 

Rather gutted as we just finished cladding that side today. The timber in the window reveal will presmably have to come out to allow access. 

 

There just aren't enough swear words today 😡

Whats the average lifespan of 3g units?

I don’t know how timber windows are fitted with glazing units, but hopefully there will be some kind of beading holding the pane in and that’s all that will need removing.

My timber cladding reveal boards overlap the aluminum of the window which itself ovelaps the glazing unit - they'll have to come off unfortunately. Doable, but irritating given I only finished installing today.
