        "text": "Foggy windows, specifically condensation between the panes, are typically caused by a compromised seal in an insulated glass unit (IGU). When the seal breaks, moist air enters the space between the glass layers. As temperatures fluctuate, this moisture condenses, appearing as fog, streaks, or water droplets. This indicates that the desiccant material inside the IGU, designed to absorb moisture, has become saturated and can no longer perform its function effectively.",
