A desiccant (drying representative) is generally positioned inside the spacer bar to soak up any residual moisture caught during manufacturing. Nevertheless, double glazing fails when the perimeter seal-- normally made of silicone or rubber-- breaks down.
Typical Causes of Seal Failure:
- Natural Aging: Over time, weather fluctuations trigger products to expand and contract, using down the seal.
- Poor Installation: If the windows were poorly fitted or subjected to tension throughout installation, the seals may stop working prematurely.

The Impact of Misted Windows
Overlooking misted windows is hardly ever an excellent idea. Beyond the visual annoyance of obstructed views, stopping working double glazing has several cascading effects on a residential or commercial property:
- Loss of Thermal Efficiency: Once the seal breaks, the insulating gas escapes and is replaced by damp outdoors air. This drastically minimizes the window's U-value, causing heat loss.
- Higher Energy Bills: Because heat leaves more readily through compromised windows, heating unit should work more difficult to keep a comfortable indoor temperature level.
- Potential Structural Damage: Trapped wetness can eventually rot wooden window frames or corrode metal frames, leading to pricey secondary repair work.
