- The Glass: Two panes, normally 4mm thick, supply a barrier versus the aspects.
- The Spacer Bar: This separates the glass panes and normally includes a desiccant (drying representative) to soak up moisture.
- The Gas Fill: The area 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 parts fail, the window's effectiveness drops, indicating that it is time for upkeep or repair.
Common Signs That Double Glazing Needs Repair
