Steamed double-glazed sash windows Post questions and find answers on glazing, double glazing, upvc glazing, conservatory glazing, fixtures and fittings etc....

Hi folks,
Looking for opinions. We have timber-framed sash windows which are double glazed. A couple of months ago, 6 of the sealed units steamed up internally - i.e. between the panes - possibly due to weather/temperature change. Assuming the seals had failed, we arranged to have these units replaced - but the work hasn't been done yet, and after about 2 weeks, the steam cleared up, and hasn't come back for the past month (and counting). We're now not sure whether to go ahead with the replacement - which is quite expensive - or if it's not worth it and we should cancel.

Does anyone have experience with this? Is this a problem we should be looking to fix now, before it gets worse? Or is an occasional bit of steam inside the units not something to worry about?

Opinions/advice appreciated.

Thanks!
James

Hi jamoo1980
If sealed double glazing units are fitted these should not stem up. If they have in the past then the seals have gone and they will repeat the effect when conditions are right.
If the problem is not too serious and if you can cancel replacement with incurring a penalty then do so and see how it progresses over the next 12 months.
