What role do windows and doors play in moisture control?

Windows and doors play a critical role in moisture control within a building. Ineffective sealing around these openings can create pathways for air to enter and exit the structure, which can often be accompanied by changes in temperature and humidity levels. When warm, moist air comes into contact with cooler surfaces, such as glass in windows or frames in doors, condensation occurs. This can lead to various issues, including mold growth, wood rot, and structural damage.

The effectiveness of sealing is crucial; if gaps or leaks exist, they not only allow moisture-laden air to infiltrate but can also let conditioned air escape, exacerbating humidity issues inside the building. Properly installed and sealed windows and doors help maintain a controlled indoor environment by minimizing unwanted airflow and thus contributing to overall moisture management.
