What does moisture between the window panes mean?

It’s critical to understand that moisture presence between window panes often indicates that the glazing is nearing the end of its lifespan. However, the formation of condensation is not the only symptom indicating problems. Signs of deterioration, such as whitish deposits or color changes inside the glass, are also common. The latter usually results from the oxidation of the low-emissivity film inside the glazing due to moisture infiltration.

Phenomena not signaling an end-of-life issue

Certain phenomena, like white clouding or ice formation, do not necessarily signal a window reaching its end of life. White clouding can result from a chemical reaction between the materials of the window pane and sun exposure, particularly in perfectly sealed units. Similarly, ice formation on the outside of windows is a normal response to condensation due to the low temperatures typical in Quebec.

Lifespan of window panes

The lifespan of a window pane is generally estimated to be between 15 and 20 years. However, it can be affected by various environmental and structural factors. For instance, prolonged exposure to sunlight and significant temperature variations can lead to premature aging. Glass facing south or located in areas with strong climate fluctuations are particularly vulnerable.

Does energy glass have a shorter lifespan?

Energy-efficient glass, designed for better thermal insulation, can indeed experience quicker deterioration. Temperature variations put pressure on the sealing joints, potentially reducing the longevity of these window panes compared to clear glass panes.
