Fresh outside air is taken in either through soffit vents or in through the system itself. This cooler air rises from these intake points and mixes within the ceiling or building space to create a natural flow of air that leaves the hot air escaping through the top of the ridge/skillion.
Simultaneously, a positive airflow also crosses over the ridge of the house creating a negative pressure which pulls air out from the ridge vent. Effectively, two thermal effects create a continuous flow of air allowing cool air into the roof/building space and extracting hot air.
The revolutionary louvre system provides an all-in-one, multi-use solution that has changed the roofing industry in Australia. Vent-A-Roof® is the proven premium alternative against traditional ventilation systems such as whirlybirds, powered vents and commercial ridges on metal roofs.
