What is Subfloor Ventilation?

Subfloor ventilation is a crucial component of a healthy home. It involves the exchange of air beneath your home, targeting the often-neglected space between the ground and the underside of your floor. This space, if improperly ventilated, can lead to a range of issues, including moisture buildup, which can result in mould growth and damage to the structural integrity of your property.

How Does it Work?

Our subfloor ventilation systems work by ensuring a consistent flow of fresh air into the subfloor space, while expelling damp, stale air. This process is achieved through strategically placed ventilation fans, which help maintain optimal humidity levels.

Explanatory information directly from The
National Construction Code Australia.

Take a look at the graph from the National Construction Code to understand the impact of effective subfloor ventilation on humidity levels:

“Subfloor ventilation is cross ventilation of the subfloor space between the underside of the subfloor and the ground surface under a building.

Ground moisture rising into or entering the subfloor space can create a damp environment which encourages timber rot, fungus growth and the potential for termite activity. Subfloor ventilation increases air flow, reducing any damaging water vapour in the subfloor space.”
