Moisture condensation inside a skylight.

A “broken seal” on a window is the description given when there is evidence of moisture condensation inside a window pane between the glass panels. However, the term is not completely accurate as the moisture condensation can be formed by either an actual broken seal, the inability of the window desiccating materials (typically silica) of absorbing the moisture of the air inside, or both.
