Looking outside has become impossible, so much fog is accumulating on your windows? Do not take this condensation problem lightly: it reflects excessive humidity in your home. To counter this phenomenon, follow our anti-condensation advice on your window glazing.
How does condensation form on the window?
Condensation results from the meeting between warm, humid air from the inside and cold from the outside on the cold surface of a window. The moisture then turns into water droplets on the glass. By passing through them, the light causes the effect of blurring or fogging on the glazing.
Why so much condensation on the windows?
If condensation builds up on the outside of your windows, there's not much you can do about it except wait for it to disappear. Conversely, recurring condensation inside the window is proof of poorly managed humidity:
Excess heating (or air conditioning in summer)
Poorly adjusted ventilation
Shower or bath too hot in the bathroom
Dishwasher, oven or hotplates widely used in the kitchen
What are the consequences of condensation inside?
Certainly, persistent fogging is annoying, but above all it can cause lasting damage to your interior: smell of humidity, mold, stains, etc.
How to limit the appearance of condensation?
Solution 1: ventilate
Take one action to contain condensation in your home:
ventilate!
Opening the windows at least 15 minutes a day (including when it rains) has three advantages:
Allow humidity to escape from the home and do not allow it to accumulate on the windows.
Reduce the temperature: this rebalances the indoor hot air-outdoor cold air balance.
Ventilate: the air flow thus created evacuates the condensation more quickly.
Solution 2: Reduce Humidity and Circulate Air
Of course, you cannot live with your windows open all day, otherwise you risk drastically lowering the temperature in your rooms in winter.
Reduce humidity and optimize ventilation in your home using simple actions:
Using the kitchen hood
Leave the doors open (except the bathroom)
Check the air outlets at the windows
Invest if necessary in a dehumidifier
Solution 3: limit heating
Lower the radiators in your home to avoid too great a difference between inside and outside.
Solution 4: anti-condensation products
In case of localized condensation, you can use anti-condensation sprays like those sold for car windows. Also consider a homemade solution: hot water + a few drops of dishwashing liquid + 1 dose of white vinegar, spray then wipe with a microfiber. Coating the windows with soap or shaving cream also works well.
Summary
By ventilating your rooms and taking care of ventilation, you can easily limit condensation on your windows. Be aware, however, that if it accumulates between the panels of your double-glazed windows, it may be a sign of an aged leaf or a damaged seal. Consider a quick change to gain comfort.
