Windows fog up from the inside: With simple tricks against humidity

If your windows mist up from the inside, it is due to excessive humidity in the room. This phenomenon occurs mainly in the autumn and winter months when the temperature difference between the warm interior and the outside is too high and the moisture condenses on the cold glass pane.

What to do when windows mist up from the inside

During the cold seasons in particular, condensation on the window is more likely to form. The condensation forms when moist air cools down on the windows.

• If your windows are misted up in the morning and you notice condensation, this is basically an indication that you need to air your rooms thoroughly.
• By ventilating properly, you can usually prevent condensation from forming and thus prevent further problems.
• To do this, open all windows and doors and leave them open for a good 10 to 15 minutes. This is the only way to ensure a thorough exchange of air.
• Short ventilation is usually not sufficient for this.

Why you should not ignore condensation

If condensation still forms on the window despite airing it, you should not ignore the problem but get to the bottom of the cause.

• First have a specialist company check whether your windows are well insulated.
• If this is not the case, it is a good idea to have this problem rectified as soon as possible.
• Otherwise mould may form on the windows.
• If you have condensation not only on the windows but also on the furniture and walls, this is a clear sign that the humidity in your rooms is too high.
• In such cases, ventilation is usually no longer sufficient to get the moisture out of the room. In this case, it makes sense to get a dehumidifier or condensation dryer.
