What Causes Double Glazing Fog?

Fogging or condensation within double-glazed units usually suggests a failure in the seal that holds the glass panes together. Here are some primary reasons for double glazing fog:

1. Seal Failure

One of the leading reasons for fogging is the breakdown of the seal between the glass panes. Gradually, the rubber seals might wear down due to age, climate condition, or producing problems, allowing moisture-laden air to get in the cavity.
