Condensation that is able to get into the space between the glass panes is the most common cause of misting on the outside. Typically, the condensation appears as a cloudy coating and decreases the transparency of your window. The misting inside double glazing is much more serious, and is a sign that the seals on the insulating unit are not working properly.

This can be as an outcome of poor installation, or perhaps insufficient drainage and spacer blocks. The moisture then begins to penetrate and over time, it can cause the seals to break, leading to the onset of condensation between the glass panes.

Another common reason for a failure of a double glazed unit is that the desiccant inside the unit gets saturated. The desiccant absorbs excess moisture and stops it from getting into the glass panes' gaps. But, when it becomes saturated, the desiccant begins to lose its capacity to absorb water and eventually the moisture between the glass will increase, leading to the mist that is commonly seen.

A swell of moisture forming between the strip of aluminium and the seal is often the first indication. This is not a simple solution and it is recommended to replace the entire unit.

This is typically caused by inadequate ventilation. The heat in your home may be trapped if there is no air flow. This can cause humidity buildup. This is typical in kitchens and bathrooms where there is a lot of humidity. If you have a double-glazed windows that is cloudy it is essential to inspect the ventilation and decrease the humidity levels in the room to stop condensation from forming.

The anti-moisture grains inside the spacer bar will be saturated by water and stop working as efficiently.

Condensation on the room-facing side of your double-glazed units indicates that there is a ventilation problem in the space or property that needs addressing. It could be a result of a variety of elements and it is normal for new double glazing to display condensation on the outside, if it's a top quality sealed unit that has a top-quality Argon gas fill, however it will go away throughout the day as the glass gets warmer and the air temperatures rise.
