Why is this happening?

[okgo]

My flat is 3rd floor in a 1930's block fairly thick walls etc, double glazed heating via radiators.

My room is fairly large, 16x16 and has a double aspect, so lots of windows. Now this room is by far the coldest in the house which I think is because of the windows! The real issue though, every night the windows fill with condensation and make the room very damp, and if I don't clean them off every day they mould

Is there anyway to stop this? As I hate damp, and its very annoying having to clean all 8 windows every day!!

Put in double glazing... and then turn the heating up.

ventilate.

I reckon its a ghost. A really ghosty one.

You need more ventilation

[okgo]

If I ventilate then the room becomes baltic..

[f13ldy]

Turn heating up a notch.

Open a window slightly when you are in there.

Do you do any ironing/dry laundry in there as well?

[A911DOM]

Get yourself a dehumidifier (sp?) of sorts.

You can get the expensive electric ones, or the plastic tub with granules that trap the water.

Either way it should help with the condensation.

Open the windows for ventilation.

I've got the same issue at home, how do you add ventilation without leaving the windows open all night?

Open the little ventilation strips at the top of the windows...

Physics answer:

As the room cools, the moisture contained in the air will condense to liquid. This will take place where there is the largest temperature differential. In this case the windows.

If you're wiping the windows with a towel or wash leather, then hanging it up to dry in same room, you're not removing the water, just moving it around.

Possible solutions:

- Leave the heating on all the time, if it doesn't get cold, it'll never condense.

- Remove the water in the air using a dehumidifier, and avoid letting more moisture into the air, primarily by not drying clothes inside. Get the windows open on a dry, windy day to get some fresh air in.

- Suck it up and keep cleaning until the summer, let it dry out and get rid of the smell, and move house.

I await the inevitible criticism, and will hopefully learn something from others, as we have this problem. (Anyone looking for a house in about 6 months in London?)

Do your windows have trickle vents at the top?

[okgo]

All very well.

I don't dry clothes in there because its nasty in the air, as you said.

I do have the heating on as hot as possible, but the radiator is on the other wall.

I have a vent, its open at all times, but seems to feck all. As said, if I open the window the whole room by morning would be freezing.

So a de-humidifyer could be the answer..

[911motorsport]

I had this in one of my back rooms that still has the old style windows. Mine however only has 6 windows so it's not that.

[JonX2C]

buy a dehumidifyer thingy!

I don't have any of those. We do dry clothes in the house as it's impossible outside at the moment and the tumble dryer is ste.

The radiator is just below the windows so it should be warm. Although in the bathroom it's freezing and the radiator just doesn't kick out enough heat.

Are de-humidifiers noisy / expensive?

[okgo]

Yes they are expensive as I just looked.

what are these crystal things like?


ETA don't worry its just been lost forever in homes and DIY

Do you have curtains over the radiators? Just read that it could be a cause as well.
