This can affect the insulating properties of your windows and lead to a number of problems. Condensation occurs when warm air comes into contact with cold surfaces and cools down to its dew point. If this process isn't controlled, your windows can become cloudy. Reduce Indoor Humidity If your double-glazed windows are misting the reason is that there is excess water or humidity in the air. This water will condense when it touches a cold surface, such as the glass in your window. If you wish to avoid misting, keep the room well ventilated. Make use of extractor fans to lower humidity in rooms that are steamy. This will stop condensation from forming on your windows by keeping the humidity at a minimum in these rooms. A wide gap between your double-glazed windows will ensure that they are free of mist. If the gaps between the panes of windows are not enough the moisture could get in, and the seal may break, resulting in misted windows. In the summer, it's a good idea for you to keep your windows as open as possible. This will help to keep the air in your home fresh and cool and will prevent warm air from escaping through the gaps. Also, keep your blinds and curtains away from windows. If you hang your curtains over the glass, condensation will build up. This will also cause misting in humid air. Another important aspect of windows' ability to resist condensation is its insulating properties. Double-glazed windows are constructed from two separate glass panes that are sealed with an interlocking bar that is placed between the glass. The spacer bar is made of dessicant, which is designed to hold and absorb water vapour from the air. When the window cools down the silica will release this water vapour, stopping it from reaching its dew p
