The space between the panes is filled with dry air or an inert gas like argon to offer thermal insulation.
A desiccant (drying representative) is normally placed inside the spacer bar to absorb any recurring moisture caught during production. Nevertheless, double glazing stops working when the perimeter seal— typically made from silicone or rubber— breaks down.
Common Causes of Seal Failure:
- Natural Aging: Over time, weather variations trigger materials to broaden and agreement, wearing down the seal.
- Poor Installation: If the windows were incorrectly fitted or subjected to tension throughout setup, the seals might stop working prematurely.
- UV Degradation: Constant direct exposure to severe sunshine can break down the chemical bonds of the window sealant.

- Loss of Thermal Efficiency: Once the seal breaks, the insulating gas leaves and is changed by damp outdoors air. This significantly minimizes the window's U-value, leading to heat loss.
- Higher Energy Bills: Because heat gets away quicker through jeopardized windows, heating systems must work harder to preserve a comfortable indoor temperature level.
- Prospective Structural Damage: Trapped moisture can ultimately rot wood window frames or wear away metal frames, causing pricey secondary repairs.
