Many homes today are closed tight during the day, for security reasons. This restriction on air movement can cause stale air and odours to accumulate, trap heat, and increase the concentration of household pollutants. The result is a more unpleasant environment with increased levels of allergens and asthma triggers.
Constant movement of air within the home and exchange of air with the external environment will help to alleviate these problems. This can only be achieved by forceful removal of air with the facility for replacement air to enter the home.
This process of replacing hot, stale air with clean, fresh air makes your life more comfortable in three ways:
A more comfortable summerExtraction of super heated attic air enabling it to be replaced by fresh air through ceiling registers or eave vents. Roof space temperatures can be lowered, in turn reducing the amount of heat radiating into the home.
Lower energy billsDucted energy bills. Ducted air conditioning systems operate far more efficiently with roof space ventilation.
Less roof space moistureUp to 12 litres of moisture per day is drawn into roof spaces from shower and kitchen fans and can cause mould and mildew. Adequate roof space ventilation can help maintain a dry atmosphere.
