What Is Underfloor Ventilation

What is underfloor ventilation? The underfloor is the area that makes up the bottom foundation of a building. The sub floor ventilation system provides protection to your house against multiple issues, such as molds. … It assists you to keep moisture away from your house.

Why do you need sub floor ventilation?

The purpose of sub floor ventilation is to replace the moist air with fresh dryer air. … In order to ventilate more effectively, installing sub floor fans will enable you to extract moisture and damp/stale air from the sub floor area and replace it with fresh air drawn from the outside by one or more sub floor fans.

Do you need airflow under a house?

Surface soil might appear dry, but hide a lot of moisture. As the moisture evaporates, it comes up through the soil and under the home. Without adequate ventilation, this moisture is trapped under the house with no way out. This is why the air under the home might feel damp, even if there’s no visible water source.
