Whirlybirds are wind-powered ventilation systems used to cool down properties in warmer climates. They minimize excessive temperatures in summer and remove excess humidity and dampness in the winter. One of the primary benefits of installing a whirlybird is the potential for reduced energy bills. They are effective in both hot and cold conditions and enhance the effectiveness of other insulation materials. They are also quiet and weatherproof. Another great feature is that it removes excess moisture, meaning less chance of dampness, mould and the hassle and potential health risks they can cause.
