Double glazed windows (also known as insulated glass units or IGUs) consist of two panes of glass separated by a spacer and a layer of air or inert gas (usually argon or krypton). This design significantly improves thermal insulation and soundproofing. However, when a crack appears, it compromises not just the appearance but the entire functionality of the unit. Unlike a single-pane crack, a crack in a double glazed window can have more complex consequences due to the sealed cavity between the panes.
