We often get asked the following question from our customers: “I have child safety opening restrictors on my windows. Can I remove them? I need more ventilation!”
The answer is no, you can’t remove them – they are part of the building code and it may be illegal to remove them. You will usually find restrictors on windows that are on the second or third story of a house, or higher on apartment buildings. The window opening restrictor prevents the window from opening any further than 120-125 millimetres and they can be found on all types of windows that open outwards as well as sliding windows.
There is a type of window restrictor that has a key where you can remove them quite easily – they’re called removable restrictors – but they’re only supposed to be removed in case of fire. They are not meant to be removed willy nilly; they are required to be there for child fall from height safety.
