Why do windows "sweat" from the inside? Simple tips will help get rid of pesky drops

Autumn came, and the windows in my house began to "cry". At first I saw a few drops on the glasses in the evening. Now, the end of September, windowsills literally flooded. To the point that we have to collect water from the window sill with a sponge.

Terribly annoying. Plus, in the air the smell of damp. My neighbor at all on the wallpaper settled plastic fungus. Bad for the interior, and to human health!

My irritation caused me to spend the whole research on the Internet and on the forums. I know that for a solution to the problem must first find the cause. And along the way I got a lot of exciting discoveries. I share with you useful information.

I will not write about the marriage of plastic windows, because it is a very different case.

I do not think that most of my readers wish to read scientific research. Therefore I settle for only one physical term - dew point at which water from the gaseous state into the liquid. This is the process we see in the windows.

Dew point appears on a plastic window when the warm air inside is in contact with the cold outside. So the windows do not sweat inside the summer, when the outside temperature and the outside is about the same. But in winter, autumn and early spring windows begin to "flow".

And I had no idea now while drown apartment with natural gas, regularly ventilate the room, so as not to let valuable heat. And here lies the error. The apartment has no fresh air, so the natural air ventilation is impaired and condensate, which appeared due to the dew point does not evaporate as it would occur in an ideal.

Therefore, it is necessary to check the correct functioning of the home ventilation, include the hood in Food cooking time and, most importantly, - still ventilate the room at least 15 minutes, 2 times a day. Fresh air can not hurt! A heat - more heat the :)
