CYCLONE SCREENS
Cyclone screens are used to protect windows and doors (dominant openings) of
buildings from being breached by the impact of air borne debris during a cyclonic
event.
Should the internal pressure of a building become positive as a result of a dominant
opening being breached, together with forces generated by the external wind upon
the outside of the building, this may cause further damage resulting in further air
borne debris or failure of the building structure.
It is highly recommended that cyclone screens (as pictured below) be installed and
pinned in place to shield against the impact of airborne debris. This measure will
enhance the safety and comfort of occupants during a cyclonic event.
WARNING - It is important to remember that cyclone screens are not to be used as
security screens and should not be padlocked or permanently fixed as in the event
of a fire or other emergency residents may need to exit through a window. Cyclone
screens only need to be pinned in place during a cyclonic event.
