double glazing
What causes condensation in double glazing?

Most commonly ‘misty’, ‘cloudy’, or ‘blown’ double glazing as its know in the industry is usually a sign that your double glazing has broken down.

Why does double glazing break down?

There are various reasons as to why your double glazing breaks down and causes a build up of condensation, the most common reason being time.

Over time the desiccant, a small grainy like substance that is used within your double glazed units spacer bar to absorb any water vapour that manages to get past your units edge sealant, becomes saturated. As a result of the desiccant not being able to absorb any more water vapour, a build up of condensation between the two panes occur as the moisture has nowhere to escape.

Other reasons could be down to poor fitting, broken or faulty seals and poor maintenance. Cleaning you windows with harsh chemical be harmful to your double glazing.
