Condensation on windows poses mold risks during autumn and winter

As temperatures drop during the autumn and winter months, condensation on windows is becoming a common issue in many households. This phenomenon occurs when warm, moist indoor air comes into contact with cold glass surfaces, causing water vapor to turn into liquid droplets.

While seemingly harmless, persistent condensation can lead to significant moisture buildup, potentially creating conditions for mold growth on window frames, walls, and corners. Key contributors to indoor humidity include daily activities such as cooking, showering, and breathing. Notably, drying laundry indoors is a major source of moisture; a single washing machine load can release approximately 2.5 liters of water into the air.

To mitigate these risks, experts recommend short but intense ventilation by opening windows fully for a few minutes several times a day, rather than leaving them slightly tilted. Additionally, drying clothes on balconies or in well-ventilated areas is advised to prevent moisture from spreading throughout the living space.
