In time, due to natural wear and tear, thermal growth, or bad installation, the border seal can break down. When this occurs:

1. Moisture Enters: Outside air and humidity discover a way into the cavity between the panes.
2. Condensation Forms: As the temperature changes between the cold outdoors and warm indoors, the trapped moisture condenses on the interior surfaces of the glass.

Here is a quick contrast of repair work versus replacement to assist comprehend why:

Defogging/ Repair

Complete Glass Unit Replacement

Cost

Less expensive upfront

Moderate

Longevity

Temporary repair (typically stops working once again within months)

Long-lasting (often comes with a 5— 10 year guarantee)

Thermal Efficiency

Poor (does not restore the lost insulating gas)

Excellent (brings back initial U-value and insulation)

Aesthetics

May leave residue or drill marks
