Introduction To Subfloor Ventilation

Maintaining adequate underfloor/subfloor ventilation is an important factor for the health of a home or building.

Structural renovations, the installation of ducted heating/cooling or landscaping/paving close to external walls can all reduce/prevent the natural airflow through an under floor space. Blocking or not having enough external vents around the perimeter of a building can have a detrimental affect on the subfloor space.

Musty odors, warped floorboards, rising damp and moist under floor soil are all common signs of poor under floor ventilation.

At Subfloor Fans Warehouse we stock a range of mechanical ventilation systems to suit your situation to help control the above problems. Mechanically drawing air from the space allows fresh air to enter, which in turn helps dry out the soil moisture and remove humidity from the space. For more comprehensive information relating to a number of different aspects of subfloor ventilation read our Subfloor Ventilation FAQ and DIY sections.
