Why is fog on the outside of your windows a good sign?

Did you recently contact Solution Thermo for an upgrade to your window panes? Noticed some fog on the external surface? Don’t worry, it’s a positive indicator, especially during cold and humid seasons like autumn and winter. Let us explain why.

What is the dew point?

The dew point refers to the temperature at which air is fully saturated with moisture, leading to condensation. This is what manifests as fog on your windows.

How does the dew point influence your windows?

The concept of the dew point is key to understanding why fog appears. When the external air temperature hits this point, moisture will condense on colder surfaces, like your windows.

Exterior fog: A marker of efficiency

If fog is visible on the outer surface of your windows, particularly at the glass center, it indicates that your new window treatment is effective and well-insulated. This is most noticeable when there are significant temperature changes and is amplified by modern double or triple-pane windows with energy-efficient film.

No cause for concern

The appearance of exterior fog signifies that your window treatment is effectively keeping heat indoors. This results in a colder external surface, encouraging condensation when the dew point is reached. There’s no need to worry. However, external factors like wind or obstructions might prevent this from happening but are not indicators of inefficiency.

The advantages of efficient windows

Effective windows don’t just minimize interior fog; they also offer better thermal and acoustic insulation, leading to energy bill savings and enhanced comfort.

Caution about interior fog

Should you notice fog within the window, it could point to an underlying issue.
