Condensation on Double Glazing

[WeAreBongo]

I have a double-glazed bay window in the main sleeping bedroom of my house. I have noticed that every panel in this window is soaked with condensation in the morning, especially so during this current cold snap. Why is this? I thought double glazing reduced condensation? The windows were in when I moved into the house - could all panels be - to coin a Christmas phrase - goosed?? I thank you.

If you mean inside the panels then the units are knackerd. on the surface inside the room is pretty normal.

Central heating will cause moisture to condense out of the air and deposit itself away from the heat source, ie on the windows and also the walls, though that is less visable. Double glazing itself will not reduce condensation, how could it? you have to open the windows to let it out. or you will eventually cause damp, mildew, mould etc.

Hi, As Loosehead said, if the condenstation is on the outside of the unit then this can be quite normal.
When a person is asleep he gives off between one to two pints of moisture through the night. In most houses now there is very little ventilation to allow this moisture to escape so it congregates on the cold window glass.
You maybe able to leave your window slightly open in the trickle position which will help.
Alot of new houses now have trickle vents that will help the situation.
It is quite normal but can be very annoying.
If the condensation is inside the unit then the unit is breaking down and the most likely solution is to replace the unit. Regards Al

Hi Both answers above are correct, you need to ventilate, open the trickle vents or the window when your asleep, also you can put bowls of rice or salt on the window ledges this will help soak up any moisture, and you just change it every few days. But if your not prepared to ventilate you will have this as a ongoing problem, try it for a few days i bet it works

Seals can fail in the glazed units over a period of time and then you will get condensation between the glass panels. This doesn't mean replacing the window, just the glazing units and this can be done easily by most glaziers nowadays.
