Fire Shutters

The Gorter Fire Resistance Shutters are compliant with Australian Bushfire Standards. This process has now been completed and the fire shutters passed the testing requirements and now are suitable for use throughout Australia.

The Fire Shutters are one part of the series of innovations that evolved as a result of Cox Architects® research project into Bush Fire Resistant Construction which started over 10 years ago. The Fire Shutters are manufactured by the Gorter Group and supplied by Gorter Hatches Australiasia, under licence from Cox Architects®.

The Fire Shutters incorporate several patented pieces of technology in order to provide a complete building envelope that can withstand the most severe bushfires in Australia.

Fire Shutters was to provide fire protection

The initial requirement of our Fire Shutters was to provide fire protection to the openings of a building when exposed to a bushfire attack. During the design and development of the shutters, it was concluded that the rigorous construction requirements to meet such an attack, also led to other opportunities and uses for the shutters which include, but are not limited to, the following:

  • High resistance to impact loads caused by flying projectiles
  • High resistance to cyclones High thermal insulation against cold and hot temperatures.
  • High security protection to a building by protecting the openings
  • The opportunity of providing highly insulated sun hoods to windows and openings
  • The opportunity of providing privacy screens using the upper and lower panels
  • The opportunity of deleting the requirement for curtains and other window furnishings.

Survive a full-scale bushfire attack

The design parameters which Cox Architects® set were high and unique. It was observed that in order to survive a full-scale bushfire attack, the thermal resistance of the openings (eg windows) was not sufficient to ensure full protection against fire. This is because under bushfire attack, high winds produce many flying projectiles which can easily penetrate standard glazing of windows. Once the building envelope has been compromised by such penetration, the fire protection of the building has been lost and the building can no longer be regarded as a safe haven for occupation during the fire.
