Window condensation

Thanks all, I assumed a new window would do the trick but apparently not the case?
i should add windows in other rooms don’t do that (we only had 2 sleepers in one), but they are newer windows (no lead windows). 

im just wondering if it might be that the lead window lets some air through, which gets in contact with the inner window? Which is warmer due to it being inside, and that’s why it happens in those old windows but not in the new ones? 

The lead work shouldn't let any air through. It's just stuck onto the glass. It looks like your lead work is on the inner surface of the outer pane.

We have some where the lead work is stuck on the outer surface of the outer pane.

I've still got single glazing, so the windows are often soaked in the mornings. A wife with a few J cloths is quite an efficient dehumidifier.

Did you really mean "a wife" or was that a Freudian slip.

I'll let you know after I've googled Freudian slip.

Leave your windows slightly open at night. In the morning run a good quality desiccant dehumidifier for at least 4 hours then make sure to empty it daily. Between March and October you should not need the dehumidifier.

Perhaps it's just how my mind works. I imagined you were being humourous by purposely mistakingly saying "a wipe" rather than "a wife".

Somebody said you should never try to explain a joke.

One way to look at it is the window is working a dehumidifier. The key is to remove the water each day before the frames go mouldy and as someone already suggested a karcher window vac is ideal.

Try and keep the humidity in the house below 60% too. Always shower with a good extractor fan running and open the window in bathroom for 10 mins after. Always use extractor fan when using the hob.

Otherwise use a dehumidifier but that's more costly to own and run but better than getting mould.

We’ve just had a couple of new windows. North facing large windows. They are in the kitchen, so no one breathing overnight. We now get condensation on the outside lower edge. It’s a sign they are well insulating. We have a trickle vent as the window was a replacement but 3 times the size of previous window, so building regs required it.

It's not a traditional leaded glass window, it's sticky tape that looks like lead stuck to the glass of a standard sealed double glazed unit. Not sure why this forum is obsessed with condensation (normal) and dehumidifiers. Just crack the window open once everyone is up, the average human breathes out loads of moisture while sleeping, more for more vigorous activities that take place in the bedroom, like reading or doing a crossword/Wordle.

Tried that but typo led to a frau in a slip, unexpected but not unpleasant tangent.
