But what do you do when you don’t have a window to open? I like many strata dwellers only have large glass sliding doors. I do have one window but in order to have cross ventilation, one would need an opening on the opposite side of the unit. I don’t fancy leaving my balcony door ajar at night being grond floor. So perhaps this is a design flaw in strata complexes. Perhaps future strata development plans should include louvre windows alongside the balcony doors to provide ventilation without the need to keep doors open.
I got around this problem but fitting pin style window locks at the top of the sliding doors, with holes drilled in the top track frame. I can open the doors wide enough to let air in, but not a body. A similar lock on the OUTSIDE of the door, at the other end, can be used to prevent someone from trying to lift the door out of the tracks. Sliding screens keeps the insects out.
