Even if the grid shutter door is closed, it will not give people the feeling of being stuffed into the box, and it will still be breathable. It can also be used with aluminum alloy roller shutters to achieve ventilation and prevent peeping. {Note: There are empty grid doors in the middle of the door, there are light-transparent rolling shutter doors, light-transmissive non-ventilating shutter doors (name is too long), mesh shutter doors (not all grid shutter doors are meshed throughout the door) Some have holes in the upper or middle part)
