        "text": "Foggy sliding door glass, often seen as condensation or a milky appearance between the panes, indicates a seal failure in your insulated glass unit (IGU). IGUs consist of two or more glass panes separated by a spacer, creating a sealed air or gas-filled space. When this seal breaks, moisture-laden air enters the gap, leading to condensation and deposit build-up, causing the foggy look. This reduces visibility and insulation performance.",
