I live in a complex with four two storey town houses. All our windows have window locks so they can be secured in the fully closed position. Are we also required to install window opening limiters, so windows can be locked at 12.5cms?
An owners corporation will be required to install safety devices that allow windows above the ground floor to open to a maximum width 12.5cm when the lock is engaged
I read this as the lock must allow a max of 12.5cm opening but if the opening is 0cm it still complies so no I don’t believe you need do anymore. You also have until 2018 before this becomes mandatory anyway.
