Before diving into repair work, it helps to understand the anatomy of a double-glazed window. Unlike single-pane glass, a double-glazed unit (typically described as an Insulated Glass Unit or IGU) includes two panes of glass separated by a spacer bar.

• The Glass: Two panes, generally 4mm thick, offer a barrier against the components.
• The Spacer Bar: This separates the glass panes and normally includes a desiccant (drying agent) to take in wetness.
• The Gas Fill: The space between the panes is typically filled with an inert gas, such as argon or krypton, which enhances thermal performance.
• The Seal: Primary and secondary seals hermetically bind the glass to the spacer bar, keeping the gas in and moisture out.

When any of these parts stop working, the window's effectiveness drops, signifying that it is time for upkeep or repair work.
