Sub Floor Ventilation
Adequate sub floor ventilation is essential for buildings with a sub floor.
How much ventilation will depend on the building materials, age, position, and specific geo location. Factors such as type of ground density, run off, exiting drainage, or lack thereof are factors when assessing the sub floor ventilation requirements.
Sub floor ventilation systems replaces the moist air with fresh dry air where you do not have the natural airflow, you can install a sub floor ventilation system which includes the installation of sub floor fans, so the moisture and damp air from the sub floor area is extracted and replaced with fresh air from outside via the sub floor fans.
