Subfloor ventilation uses supply air and exhaust fans and vents to help circulate air under a building's suspended floor to manage humidity and keep the air fresh under the home.

Humidity and moisture can build up under a house in the subfloor area creating mould, rising damp and potentially leading to structural issues and the infestation of pests such as termites. Unhealthy air in a building's subfloor can seep into the living spaces and effect the environment and air quality. Australia's National Construction Code requires that subfloor spaces are suitably ventilated to help mitigate these issues. Subfloor ventilation introduces fresh air and circulates air under the house to help keep the space dry and reduce the risk of moisture build up.

Fans positioned in the wall or under the house extract damp stagnant air and draw in fresh air from the outside. With improved humidity levels under the house, the risk of rising damp is reduced.

The range includes mechanical ventilation products that are suitable for use in under-house environments. It includes our Subfloor fan and inline fans, duct and external vents.

They are suitable for homeowners, and trades such as builders, electricians and plumbers, managing subfloor moisture issues.
