How to ventilate a south-facing apartment to ensure a circulating \”cross-window\” was once a question I considered, but I didn\’t expect it. , this problem is actually quite easy to solve, yes, just make a ventilation security door.

But this so-called ventilation Are security doors really worth it? After so many years of personal use experience, this kind of security door belongs to Jeonnam. The layout of the house is as high as the sky, and the north-south transparent house layout is ignored.

Why do you say that? ? Let’s take a look at its advantages and disadvantages and we’ll understand.

Obvious advantages of ventilation security doors

Ventilation and anti-theft doors are actually not strictly needed. They are generally chosen by people with South-South apartment types. Its advantages are also obvious.

①One, naturally fresh air. There is a small ventilation window above the security door. When opened, it can allow indoor air to form convection. The originally stuffy southern apartment type has transformed into a north-south open one, greatly improving the ventilation capacity.

②Second, does not affect the normal use of the door leaf, and there is no need to fully open the door The mesh fan in the middle can ensure safety and prevent mosquitoes and insects. In fact, it is quite comfortable to use for ventilation.

③Third, there is an additional visual window. Compared with the peephole, it is more convenient to observe people outside the house after opening, which can be regarded as a small advantage.

Ventilation security doors have many shortcomings

Then why does it have so many advantages, but many north-south transparent apartments still \”disdain\” it? That\’s because, in addition to the advantages, there are more disadvantages.

①Odor in the corridor

The most difficult thing for me to accept is the problem of odor in the corridors. Although ventilation is good, the moisture and mold odor that comes with it are more likely to enter the home. Some neighbors in the old community are not particular about it. If there are piles of vegetables and garbage in the corridor, the smell will be even more unbearable.

②Poor privacy

Poor privacy as well One thing that needs to be considered is that although ventilation has been increased, after all, there is only a window screen, which can block mosquitoes but not the view. When people come over and glance up, they can see the home, which makes them feel very insecure.

③Low utilization

It is also because The above problem of poor privacy is that sometimes I turn it on for a while and then turn it off when I am at home, but I can’t bear to leave it on when I am not at home. Over time, I become too lazy to turn it on and off, and the utilization rate is greatly reduced.

④Occupies indoor space

Occupies indoor space The problem is also obvious. After opening the sash on the security door, an \”iron window\” is placed in the home. It looks very awkward and invisibly takes up the available indoor space.

⑤Easy to bump

Occupy Not much to say, it is easy to be bumped by this small window, and it is easy to get in and out.If you don\’t close this small window when you open the door, it might cause a bruise on your body anytime, which is really troublesome.

⑥Poor sealing

The last step is sealing The performance is poor, not to mention the air leakage in winter and the problem of air filling with the range hood, but the noise reduction ability is much worse than the ordinary one-piece anti-theft door. These are what you need to consider when buying it.

Summary at the end of the article

All in all, my personal opinion on whether a ventilation security door is worth it is – unless it is a South-South apartment with really poor ventilation, it is the most suitable choice besides the fresh air system.

But if your home has a transparent north-south layout and you want to enhance the ventilation, I advise you not to consider buying this kind of ventilation security door. Wouldn’t a ventilation fan be good?

If it were you, would you choose to buy this kind of ventilation security door?
