There are many different types of windows in general use, e.g. aluminium or wooden, sliding, casement, hopper, and double-hung.
No matter what type of window you have, key operated locks should be fitted and used. All window locks should be ‘keyed-alike’ for ease of use and safety.
Ground-floor windows and windows that are not visible from the street or adjoining properties or are within an easy reach from a drainpipe, roof or wheelie bin are more vulnerable because they can be easily accessed by an intruder. These windows should be always be secured.
Window security screens
If you need to leave windows open for ventilation, consider installing security screens that are designed and installed to meet or exceed the relevant Australian Standards. Consider seeking expert advice about having some security screens hinged to allow easy exit in emergencies.
