Invisi-Maxx security screens from Alspec have been installed at a community cyclone shelter in Marrara, just 10 minutes from the Darwin CBD.
Darwin residents have constantly faced the destructive forces of cyclones, from extreme events such as Cyclone Tracey in 1974 to the devastating impacts of Cyclone Marcus in 2018. While many people prefer to stay in their own home if they have an appropriately protected space, others choose to temporarily relocate to community facilities that are specially built and reinforced to withstand the unpredictable effects of a cyclone, providing them a safe refuge as well as protection against injury.
There are now 12 community cyclone shelters scattered across the city area, including this latest addition at Marrara. While the facility normally functions as a Sikh temple, it also serves as a cyclone shelter when required. The project, which was jointly financed by donations from the Sikh community and government funding, won its builder, McT Design & Construct, a Master Builders Association award.
Alspec’s Invisi-Maxx stainless steel security screens have been installed to the windows and doors of the shelter. With winds that can reach up to 280km per hour in cyclonic conditions, these screens help prevent injury to people and damage to property, thereby, contributing to the building’s cyclone-proof credentials.
Invisi-Maxx screens are installed permanently, assuring long-term protection without compromising the ventilation, light and views.
Invisi-Maxx, described as a high performance debris screen, was developed by Alspec to specifically respond to the force of windborne items by dissipating the energy from an impact and preventing debris from entering a building. The screens are constructed from corrosion resistant 316 marine grade stainless steel attached to a heavy duty frame through a patented mesh retention system. The 1.2mm mesh screens exceed the relevant Australian Standards, having demonstrated the ability to withstand the impact of a projectile travelling at up to 44m/s.
With up to eight cyclone days predicted each season, often with very little warning, Darwin residents now have access to a facility that can offer them a safe refuge whenever they need it.
