Comprehending How Double Glazing Works

Before diving into repair work, it assists to understand the anatomy of a double-glazed window. Unlike single-pane glass, a double-glazed unit (often referred to as an Insulated Glass Unit or IGU) includes 2 panes of glass separated by a spacer bar.

• The Glass: Two panes, normally 4mm thick, offer a barrier against the elements.
• The Spacer Bar: This separates the glass panes and normally includes a desiccant (drying agent) to take in moisture.
• The Gas Fill: The space between the panes is frequently filled with an inert gas, such as argon or krypton, which improves 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 elements stop working, the window's performance drops, signaling that it is time for upkeep or repair.
