Condensation between window panes

ercork

Hi,

Over the last few weeks I've noticed condensation forming between the two panes on one of my double glazed windows. I assume this means the seal that holds the glass in place has ruptured allowing air to seep in? Can this be fixed?
The window itself is a large wooden frame bay window approx 15 years old. All the other panes seem fine - the pane with the condensation is approx 180 cm wide x 30 cm tall. If it's possible to repair it I would opt for that rather than replacing the whole window.

Its just the glass unit needs replacing not the window, repair is possible however it would need to be taken out and repaired in a factory, therefore you will need to fill the hole in the mean time, best to replace prob not much difference in the cost

That's good to know, thanks. Any idea how much a replacement pane is likely to cost? Also if you can recommend anybody in the Dublin area that would be great.

The usual cause of condensation is the seal on the unit breaking down from using the wrong type of silicone to hold in packers. The silicon reacts with the seal if there’s any touching it and it then stars to disintegrate slowly allowing moisture and air to soak in , instead of the gas. The price per pane will depend on size and whether it needs to be toughened or laminated or even both. A smallish normal pane will cost from €40 euro up but you’ll have to pay then for measuring and fitting on top of it . A lot of the time it’s safer to just upgrade the windows.

Thanks. It's part of a large bay window, 2m wide X 2m tall X 40cm deep. I'd imagine it would be very expensive to replace the entire window. Probably well over €1000? I'll look into just getting the pane replaced. It's 180cm X 30cm so will probably be a fair bit more than the €40 you mentioned. If anybody knows anybody reliable in the Dublin area you might PM me.

The glass should be around 120-140 as it will need to be toughened about will probably be around the same as there’s two call outs, one to measure and one to fit, i would just go to your local glazier and get him to call over. They will know by looking at the pane whether it’s warm, edge, low e, etc and they should be able to match.
