The reason why windows can be steamed or misty is due to a breach of the seals between the two glass panes of your sealed units. This could result from a range of causes, such as ageing or wear, the environment or even poor installation.
It can also happen because of fluctuations in temperature. As the air cools, it becomes less humid, which can cause the moisture to condense and eventually fall on the window pane. This is why it's crucial to make sure that your windows are suited to the local weather conditions and are installed and maintained by an FENSA approved window fitter.
