Whirlybird Information
During the Hot days of Summer the temperatures within a roof can reach over 70 degrees Celsius - effectively heating the entire house.
With whirlybirds installed, hot air is extracted from the roof space and fresh air is drawn in from outside, vastly lowering the temperature within the roof and throughout the home.
During the Cold Wet days of Winter the build up of moisture within a roof can cause all sorts of damage to the internal structures throughout a home. Ceiling mould is often the earliest indication of a moisture problem.
With whirlybirds installed, fresh air is constantly being circulated throughout the roof, keeping the internal structures of your home dry and preventing mould and rot from developing.
