You could break the glass panes but not go through the horizontal bars which are half inch round steel bars spaced 6" apart through the wood frame. Its not generally possible to wedge them apart and try to escape through this kind of louvered window design. It would take more than a crowbar to create enough space for escape. Maybe I suggest you inspect a typical Naco window framework when you're back in Malaysia.
More than a decade ago, I fully DIY dismantled a 3 section Naco window frame assembly to replace to aluminum sliding window at my kitchen. It was very very tough work to break everything apart and eventually dispose it.
Sad to read another similar tragedy at Kepong. Similar 2 storey terrace home.
