The primary advantage of bushfire roller shutters is that they provide protection from intruders to your house. It is impossible for intruders to remove the roller shutters because the roller shutters are very tightly fitted to the door or window and can not be taken away without a lot of effort. They are also a great visual deterrent as well as being an outstanding physical deterrent, as intruders will see the shutters and decide that attempting to gain access to your house, instead of going elsewhere is not worth the effort.
