condensation

dipsy

Hi I was wondering if anyone could shed some light on this

my windows over the last 2/3 months have suddenly been getting condensation on them, not happened in the past, mainly first thing in the morning/last thing at night

any clues???

thanks

Yes its got colder outside. Warm air condenses on the cold glasss

It's because there warm air can contain more water vapour than cold air and this will condense on any cold surface. The colder the surface and the more vapour in the air the more likely you are to get condensation. It will be more prevalent in bathrooms and kitchens but can occur in bedrooms, because of the vapour we all exhale every time we breath. Increased ventilation will help reduce the effect.

Warm air can contain more water than cold air. So when heating goes off the water is released and condenses on cold surfaces such as windows and external walls

Yes, as the others have said, it's just down to moisture in the air condensing on the cold surfaces. Air will always contain some moisture, but will be made worse if you've got clothes drying on radiators or a clothes horse. And in this cold weather, the effect becomes more pronounced.

Increasing the ventilation will help, but if you have a window open you're also losing expensive heat. A dehumidifier can help, but they can be quite costly to run, and the noise may be a problem, especially in a bedroom. The simplest solution is just to get rid of the condensation each morning by using a rubber squeegee ( is that how you spell it ? ) on the windows and mop it up with an old cloth. Takes no more than a few minutes to do, and prevents any problems with damp collecting and causing mould to form.

And then you leave the cloths out to dry ...

just wondered if my windows were damaged or something as I hadn't noticed it before i.e. over last few years..... have been giving them a wipe over in the mornings, and it is mainly in the front two bedrooms, not the rear bedroom so much or the bathroom (both at rear of the house)... thanks for all your comments/suggestions

It's been a lot colder this year than the previous two winters .... you may well not be ventilating the house as often, drying more laundry indoors, colder windows for damp air to condense on ... bedrooms are a common place for condensation as you breathe out a surprising amount of water overnight. Perhaps you are being more sensible with your heating, or have an extra person in the house? Is the front of the house north facing or more exposed?
