What is a common cause of wood decay?

Excess moisture and poor ventilation are primary factors that contribute to wood decay. When wood remains damp for an extended period, it creates an ideal environment for fungi to thrive. Fungi, such as mold and rot, can break down the cellulose and lignin in wood, leading to structural damage. Poor ventilation exacerbates this issue by trapping moisture and preventing adequate airflow, which can lead to conditions favorable for decay.

Incontrast, heavy foot traffic may cause physical wear on wood surfaces but does not directly lead to decay. Direct sunlight exposure can potentially dry out wood, which could help prevent decay, though prolonged exposure can also lead to other forms of deterioration, such as fading or cracking. High-quality wood material, while more durable and resistant to decay compared to lower quality wood, can still succumb to decay if exposed to moisture and poor ventilation. Therefore, the connection between moisture and ventilation with wood decay is critical in understanding its prevention and control.
