In time, due to natural wear and tear, thermal expansion, or poor installation, the boundary seal can degrade. When this occurs:
- Moisture Enters: Outside air and humidity discover a method into the cavity in between the panes.
- Condensation Forms: As the temperature changes in between the cold outdoors and warm inside, the trapped moisture condenses on the interior surfaces of the glass.

Can Misted Windows Be Repaired, or Do They Need Replacement?

| Feature | Defogging/ Repair | Full Glass Unit Replacement |
|---|---|---|
| Expense | Cheaper upfront | Moderate |
| Longevity | Short-lived repair (typically stops working once again within months) | Long-lasting (typically includes a 5-- 10 year service warranty) |
