Why You Need Sub-Floor Ventilation
With one of Australia's wettest summers on record it has never been more important to ventilate your home. Sub-floor ventilation must be provided to enclosed sub-floor spaces. Moisture escapes from the soil and is absorbed by the air above, raising the relative humidity of the air. This in turn will raise the moisture content of the framing members and flooring. Ventilation is necessary to reduce the relative humidity of the cool air in the space, by replacing air with new warm drier air drawn from outside the space.
To improve sub-floor air quality and reduce humidity levels beneath the floor, Austech are offering the ecoFAN by Edmonds. The ecoFAN consists of an electronic, brushless, D.C. motor and a 23cm diameter, five blade fan, installed within an aluminium powder coated frame.
The condition of the air space beneath a home can impact on mould and fungi growth, termite action and even household allergies and respiratory problems. Poor sub-floor air circulation provides a conducive environment for the breeding and activity of termites. It can also give rise to stale and musty odours which permeate into living areas. The quantity, distribution and efficiency of the vents provided is extremely important for the stability and performance of timber floors, and to reduce the risk of decay and termite hazards.
The ecoFAN extracts 4,000 litres per minute of stale or damp sub-floor air. This air is replaced by clean, fresh, external air sucked through wall grilles placed opposite the ecoFAN. Even if allowed to run continuously, ecoFAN, which draws only 6.5W, will cost less than $A6 per annum in energy charges.
