This spacer bar is filled with a desiccant (a drying agent) developed to soak up any recurring moisture caught within the cavity throughout production. The entire unit is then hermetically sealed around the edges with specialized primary and secondary sealants.
Misting happens when this seal fails.
When the airtight seal breaks down, the desiccant eventually ends up being saturated and can no longer take in wetness. As the temperature fluctuates outside, moisture-laden air is drawn into the cavity. When the sun warms the window, that wetness turns to condensation, developing the feared "foggy" appearance between the glass panes.
Typical Causes of Seal Failure:
- Natural Ageing: Most window seals have a life expectancy of 10 to 20 years. With time, the continuous expansion and contraction of materials due to weather modifications trigger the seal to deteriorate.
- Poor Installation: If the windows were fitted incorrectly-- such as doing not have appropriate drainage channels in the frame-- water can pool around the system, breaking down the seal prematurely.
- Low-Quality Materials: Cheaper systems might use inferior sealants that split or diminish faster under severe UV rays and temperature level extremes.

- Higher Energy Bills: Because your home is losing heat through the compromised windows, your heating system has to work more difficult to maintain a comfy temperature, increasing your energy expenses.
- Additional Damage: If left for too long, the constant existence of wetness can rot wood frames, cause mould growth around the window reveals, and eventually trigger the glass itself to engrave or stain.

Replacing the system is practically constantly the more affordable long-term option.
