It is a common misconception that condensation indicates a faulty window. In fact, the opposite is often true. High-performance modern windows are engineered for superior airtightness to optimize energy efficiency. However, this enhanced seal can trap indoor humidity, leading to surface condensation, dampness, and potential mold growth if the space is under-ventilated. To mitigate this, we recommend regular controlled ventilation or using windows with integrated trickle vents to balance moisture levels.
