The Mackay region is characterised by a demanding tropical maritime climate, which presents unique challenges for maintaining residential thermal efficiency. With summer temperatures frequently reaching 31°C and persistent coastal humidity often exceeding 75%, roof cavities serve as significant thermal reservoirs. This accumulation of radiant heat and saturated air infiltrates the building’s envelope, necessitating excessive air conditioning consumption and resulting in inflated energy expenditure throughout the humid summer months.

In the Mackay climate, atmospheric stagnation and moisture ingress are primary concerns for property preservation. Without active extraction, elevated humidity levels within the roof structure facilitate the development of condensation, which can lead to timber degradation and the proliferation of mould. Standard passive ventilation units frequently lack the volumetric capacity required to mitigate these effects during periods of low wind velocity. Consequently, a high-performance active extraction system is essential to maintain a dry and healthy internal environment.

WhirlyPro offers a technically advanced solution specifically calibrated for the North Queensland environment. Utilising high-efficiency photovoltaic technology and regulated by a smart thermostat, the system extracts over 700 m³ of heated, humid air per hour. This process proactively stabilises internal temperatures and mitigates moisture-related structural risks—operating entirely on renewable energy with zero recurring costs.
