Reduce Indoor Humidity

If your double-glazed windows fog, there's too much humidity or water in the air. This water will condense when it comes into contact with a cold surface, such as the glass in your window.

When the window cools, the silica will release this water vapour, stopping it from reaching its dew point and causing mist to form.
