    1. The anti-theft door with a window is good for the upper and lower windows.

    2. On the one hand, it looks beautiful, and on the other hand, it can be ventilated and airtight, reducing air pollution in the city.

    3. The ventilation window is aimed at the poor indoor ventilation efficiency of the tower, the installation of the tower corridor is well ventilated, the home ventilation is poor, the weather is hot, and many families want to open the door for ventilation, and they can open the ventilation window at the door of their own house, and make a rectangular opening on the door, and install the ventilation window (a total of three floors) into it, so as to produce ventilation effect and safety.

    4. The quality of the original anti-theft door is guaranteed, and it will add another door only on the basis of the original modification to achieve the ventilation effect, the modification time is small, fast and cheap, convenient and fast, the annual air conditioning fee is saved, and the air conditioning disease is driven away, only you only need to open the inner layer of the installation window to ventilate, you reduce the trouble of installing the door, and you save some costs.

    The security door with a window is still only one window above, mainly for the sake of wait-and-see, the door of a window is of good quality and the appearance is generous and practical.

    Is it better to have an upper and lower window for an anti-theft door with a window, or only one window on it? I think. As long as it is an anti-theft door, of course, there is only one.

    Since it is anti-theft, of course it is good to have fewer windows

It can't be changed unless you choose a new one with ventilation. Because the security doors are all fixed styles made of fixed molds. It's not like tearing down the door and opening a new hole.

Is the rubber strip on the side of the small window door leaf loose or leaking? You can go find a cool foam board, cut it into a small window size with a wallpaper knife, and then put the foam board inside a small fan to block the small window to ensure that there will be no air leakage.
