What is the effect of installing ventilation window in the middle-sized entrance door?

In fact, it is more effective to install ventilation window on the entrance door. Because the pattern of most houses may be that the door is facing the porch, and because the porch is in the middle and there is no ventilation, the overall lighting is relatively poor.

Then some families may choose to install a ventilation window on the porch door, which will make a place like the porch brighter. Because of ventilation window, the porch can better absorb the outside light through this ventilation window, so that the porch is no longer so dark.

However, such a ventilation window actually has many other advantages. Because of ventilation window, the air circulation in the whole room can be accelerated, and the overall air condition will be relatively better. Moreover, with the existence of ventilation window, the air condition in the whole porch can be kept in good balance.

However, it has several key shortcomings, because such a ventilation window is not very safe in terms of security performance. Therefore, most families may not consider installing such a ventilation window, because it is not particularly safe. If the security measures in the residential area are better and the air in the corridor is fresher, you can really consider installing such a ventilation window.
