Misted Double Glazing
Double glazing that has mist is a sign of damaged seals which allow moisture to pass through the gap between the panes. This damage can reduce the insulating qualities of your windows and lead to many issues.
Condensation occurs when warm air comes into contact with cold surfaces and cools to its dew point. If this process isn't controlled effectively, your windows will become cloudy.
Reduce Indoor Humidity
If your double glazed windows are misting it's because there's excess water or humidity in the air. The water will condense when it touches a cold surface like the glass in your window.
If you want to avoid misting, reduce indoor humidity by keeping your room ventilated and installing extractor fans in rooms that are known to be hot, such as bathrooms and kitchens. This will prevent condensation on your windows, by keeping the humidity at a minimum in these areas.
Another easy way to keep your double-glazed windows clear of mist is to ensure that there is a sufficient gap between the window panes. If the gaps between panes of windows are not enough the moisture could get in and the seal could be damaged, resulting in misty windows.
In the summer, it's a good idea for you to keep your windows as wide as possible. This will help keep your home cool and fresh, and also stop warm air from getting through the gap.
You should also try to keep your curtains and blinds away from windows. Hanging your curtains up against the glass may cause condensation to build up on the inside surfaces of the windows, and this will also lead to misting if there's too much humidity in the air.
Another major aspect in windows' ability to resist condensation is its insulating properties. Double-glazed windows are constructed of two glass panes, which are sealed together and have an interlocking spacer bar. The spacer bar has a dessicant, which is designed to hold and absorb water vapour in the air. The silica in the spacer bar will let the water vapour out when the window cools, stopping it from reaching the dew point.
The insulation of your windows may be negatively affected by a variety of factors, including the age and how well your windows were originally installed. Chemical cleaning products can also harm seals. This allows moisture to get in and warm air escape, which can cause your double glazing to turn cloudy. To reduce the chance of this happening, make use of FENSA registered window fitters and follow their directions.
Clean Your Windows Regularly
Double glazed windows are easy to clean and should be maintained regularly to avoid the build-up of dirt. Clean windows will allow more sunlight into your home, reducing the need to increase the thermostat, and will help to prevent condensation.
Clean your windows by spraying them with water and some cleaning solution. Rub the cleaning solution off with a microfiber towel and dry the window with a microfiber towel.

If you're not able to reach your windows using ladders or a rod extension, a long rod and a squeegee allow you to clean your windows while sitting on the ground.
It is normal for the exterior of windows to mist up after the air has heated up and reached its dewpoint. This can occur on any surface capable of cooling down, including windows with double-glazed glass. It doesn't impact the performance of your window, and can be easily wiped off.

If you notice condensation on your windows, this can be a more serious issue and will require professional assistance. This is typically caused by a faulty seal on the window, which allows cold air to escape and moisture to get in. The seal may be damaged because of the way windows were constructed or the cleaning solution that was used or even by aging.

Double-glazed windows consist of two panes, separated by a tiny air gap. They are then encased with a top-quality thermal barrier like the argon gas for better insulation. This makes the window difficult to break. The air gap is then filled in with a second seal, as well as a primary one. This enhances the thermal efficiency of the window and blocks moisture from entering the window. However, over time, these seals may break down due to a number of factors like age, how the windows were constructed and the use of chemical cleaning products.
When it gets colder outside, the water that is trapped in the air gaps transforms into water vapour and settles as a layer of fog on the window. This decreases your windows' effectiveness as insulators by allowing cold air to enter and warm air to escape, and increasing your heating costs.
You might have come across businesses offering services that claim to fix misty double glazing by drilling holes into the glass units and then filling them with anti-fogging chemicals.
