The requirements for openable windows in a second storey construction and in brief is as follows:

In summary as per the Building Code of Australia “Protection of openable windows states:

· In all second storey residential construction the openable part of a bedroom window must be restricted from opening greater than 125 mm or alternatively a screen placed over the window and fixed to it which can withstand the force of a child( but not a normal insect screen).

· Other alternative methods include installing a child restraint device or ensuring that the window has a complicated, two hand operating system and is unable to be opened easily. NOTE: a lockable window does not comply because the chance that the window may be forgotten to be locked or that the key is simply left in the lock is too high.
