New measures were introduced in 2013 to prevent children from falling through openable windows. According to the updated National Construction Code, bedroom windows on the second storey and above are required to have devices that restrict the opening widths of the window or screen.
Though many window types featuring the restricted opening device will have reduced ventilation, the amount of ventilation through Altair louvre windows with restricted opening is relatively unaffected.
The Brisbane home depicted in the photograph above shows how a piece of timber is being used to hold the window open with the chain winder of the window detached, most likely to get some fresh air into the room. Given that all the other windows in the house are also fully openable, the homeowner will soon be looking to install a different window type or screens, sometime in the near future.
