Understanding How Double Glazing Works Before diving into repair work, it helps to understand the anatomy of a double-glazed window. Unlike single-pane glass, a double-glazed system (often referred to as an Insulated Glass Unit or IGU) includes 2 panes of glass separated by a spacer bar. The Glass: Two panes, usually 4mm thick, offer a barrier versus the elements. The Spacer Bar: This separates the glass panes and generally contains a desiccant (drying agent) to take in wetness. The Gas Fill: The area in between the panes is frequently filled with an inert gas, such as argon or krypton, which enhances thermal efficiency. 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 components stop working, the window's effectiveness drops, indicating that it is time for upkeep or repair.
