Are your windows wet in the morning? A warning sign that you should take seriously. Read here what you can do about the condensation.
The most important thing shortly:
Cause: High air humidity meets cold window surfaces, reinforced by poor thermal insulation.
Danger: mold formation and damage to building materials.
Prevention: regular ventilation, even heating, hold air humidity at 40-60 %.
Immediate aid: wipe down the condensation and improve air circulation.
Long -term solution: replace old windows and improve thermal insulation.
Are your windows wet from the inside? A widespread problem that even worsens the current cold wave. The windows of the bedrooms are particularly affected.
Under no circumstances should you ignore this condensation on the panes. Because in the worst case it can lead to mold.
Why are the windows wet in the morning?
Condensation on the windows arises when the humidity in the living rooms is high and there is frosty temperatures outside. The water vapor contained in the air is reflected on cold surfaces such as window panes as condensed water.
The problem:If the humidity is too high, harmful mold can form. First on so -called cold bridges, but also on the walls in the long term.
According to the consumer center, a four-person household produces between six and twelve liters of water a day, which is released into the air via sweating and breathing. Pets and houseplants also add moisture to the air.

What helps against condensation on the windows?
In order to minimize condensation on the windows and to find the right balance between temperature and humidity, you should follow these four simple rules:
- Wipe the condensed water directly with a dry cloth in the morning.
- At least three times a day ventilation or ventilation. Better ventilate four to five times a day for 5 to 10 minutes.
- Always after cooking, showering, bathing and even after sleeping you should ventilate.
- Try to keep the temperature in the interiors as constant as possible. Or close the doors to other rooms if there is hardly any heat in it.
If you have problems with too high humidity, then among other things, aquariums, room fountains and many houseplants can count among the causes. In these rooms you have to think more about ventilation and heating.
But be careful: in this case, permanent ventilation with the tilted window harms more than it is useful.
Another tip to further reduce the air humidity in the rooms is that you do not dry your wet laundry in the apartment, for example. Balcony, garden, the drying room, the attic or a dry basement are more suitable.
Waterlogging can also form behind curtains and pleated blinds
A place where you less often look at whether condensation has formed on the window panes are curtains. In particular pleated blinds.
If these are pulled down to the bottom of the window, you don't see the condensation water at first glance. But the moisture likes to build up. So also think of all kinds of privacy protection what it looks like with the moisture.
Ideal indoor climate to avoid condensation
The ideal living climate should be loudConsumer centerAt a temperature between 18 and 20 ° C, with an air humidity between 40 and 60 %. However, the experts advise that the temperature in the apartment should not decrease at less than 16 ° C. So not heating at all, is not an option either.
The room temperature also influences the humidity. Warm air can absorb more water. Lifting the temperature can therefore sometimes help.
Here you should be based on the recommended temperature for the respective room. It is best to get yourselfThermo-Hygrometer(Here at Amazon*), So you always have the temperature and humidity in view.
Depending on the building fabric and insulation, differences can of course occur. While a new air humidity of 60 % is not a problem in a new building, even over longer periods, in an older building can occur from 40 % moisture damage.
Extra tip:If the air humidity in your living rooms is permanently too high, although you tease it off every day, heat properly and do not dry underwear in the rooms, aDehumidifierbe meaningful.

Lift routine is also based on the type of house
If there was a renovation of the apartment or house, the to do's can also change with regard to the habits for ventilation and heating.
If the old windows in the old building were exchanged through modern windows, for example, mold formation can sometimes occur, because the newer windows only seal much more and no longer take an air exchange.
Of course, this is positive in terms of heating energy, which is less lost and also that it is probably unfortunately than before.
But that is exactly the moment when you have to change the habits to ventilate so far. If you have just moved to a new home, it is best to ask your landlord to ask what is the best for this apartment.
