There is a growing demand for natural roof ventilation in the more remote and regional areas of Australia, like the tropics, where cyclones are commonplace. Hence these innovative roof ventilators do adhere to both the Building Code of Australia (BCA) and the Northern Territory Deemed to Comply Manual (DTCM).
This means that even if you live in a highly cyclone-prone area of Australia, you can relax knowing that your natural roof ventilator will last the distance - even through the toughest of storms.
DTCM and the Building Code of Australia
The Building Code of Australia Part 3.10.1 re High Wind Areas of Australia, details the structural and design necessities for building designs. And the Northern Territory 'Deemed to Comply Manual' references an acceptable build manual for areas of strong wind in the Building Code of Australia that has been is existence since 1996.
Most new natural roof vents have been designed and constructed to the Deem to Comply assessment by the Norther Territory Building Advisory Committee Assessment, and the Approved In Principle certification process by Northern territory structural engineers - promising superior performance of our ventilators in even the worst cyclonic conditions.
This ensures that your building will be fitted with a natural ventilation solution that offers the triple advantage of compliance, performance and the integrity to survive the next cyclone that reaches your project.
Areas of strong wind in Australia
Australia's wind regions are generally divided into four sectors.
The interior of Australia and Tasmania are Normal. The band of coast from north of Perth up and along the north coast of Australia and the east coast of Queensland to Coffs Harbour in New South Wales is the Intermediate band. Starting a little inland near Carnarvon on the west coast and up to Darwin and around to Budaberg in Central Queensland is the Tropical Cyclone area. A narrow coastal band from Carnarvon to between Port Hedland and Broome in Western Australia is the Severe Tropical Cyclone area.
Strength of Cyclones
The weakest cyclone, (Category 1) to the strongest cyclone, (Category 5) can affect your structure and natural ventilators are relied on to withstand these categories.
As part of the external structure of a building, natural ventilators are relied upon to withstand the strong winds and rain of a cyclone, to ensure the integrity of the building and roof structure. CSIRO testing and dedicated in-house engineering for cyclone regions means that you can rely on a natural ventilation system that will withstand and perform in even Category 5 events, providing the roof is still in position.
This means that even if you live in a highly cyclone-prone area of Australia, you can relax knowing that your natural roof ventilator will last the distance - even through the toughest of storms.
