Ventilation Profile
Wantirna Roofing & Weather Profile
What We See in Wantirna
Older homes with slate or terracotta roofs and no ceiling insulation were built in an era when ventilation was provided by the thermal mass of the roof covering and the permeability of the building envelope. Modern sealed construction requires deliberate mechanical ventilation to compensate for the reduction in natural air exchange.
Why It Happens
A whirlybird operates on the Bernoulli principle — wind passing over the turbine vanes creates a low-pressure zone at the hub, drawing hot air up from the roof cavity of Wantirna's Concrete Tiles homes. The extraction rate is proportional to wind speed, so performance varies with weather conditions.
How We Fix It
Placement is determined by cavity mapping — we access the roof space before finalising positions to confirm there are no obstructions between the proposed turbine location and the soffit inlet. Trusses, downlights, and HVAC ductwork can all redirect airflow in ways not visible from the roof surface.
