We can ensure safety of our child in the car by pressing one button that locks the door from the inside and disables window lowering. It's worth to use the same solution in windows of children’s room, especially when the room is located upstairs.
The best solution is to equip the windows in children's room with a protection mechanism Roto „TiltFirst” that tilts the window before opening, working in exactly opposite way to traditional windows. Additionally, the special handle that activates this mechanism is equipped with a lock. Turning the handle by 90 degrees allows to tilt the window, but not to open it. The lock is released by turning the key, which allows to rise the handle up and open the sash. The locking mechanism activates itself automatically after closing the window and turning the handle to tilt position.
