Is the ventilated security door good?

It's very easy to use.,Door-in-door?。 It depends on what price you want, if you are rural, it is recommended to buy stainless steel doors Although the price is high, it is more useful, and the gauze requires invisibility, and it will not be broken in 4-6 years. The lacquer should be lightfast to imitate copper!

I am also in the Northeast, and the family has also used a ventilated anti-theft door in the door for many years, it is really practical in the summer, but it can be mosquito-proof and ventilated, but the lock is not very convenient for a long time, my home is a mountain dog, it was cheap, and it is also very good to see a friend's home Panpan door. After a long time, the sealing of the ventilation door in the middle is not very good, and the rubber strip should be replaced regularly, once a year. It can also be sealed with cotton strips used to seal windows in winter.

Because in the dead of winter, there is no way to do it.

1. The standard of Guoxun stupid anti-theft door does not include ventilation door, because the ventilation anti-theft door is pure and balanced with ordinary anti-theft doors, and the ventilation door is not completely closed, so the ventilation door cannot meet the national standard in the anti-vandal opening time.

2. But after installing the ventilation security door, there is no need to install the security door, although the ventilation door does not meet the standard of the security door, but the window of the ventilation door is closed and locked from the house, it is still very safe, and the ordinary house does not have enough space at the entrance to install the two-layer door.

3. Some of the houses with one ladder and three households, the middle households are not transparent from north to south, so it is very necessary to install ventilation doors for such houses, and you can open the small windows on the door for ventilation when you need ventilation.

4. The ventilation anti-theft door is not the same as directly changing the anti-theft door to a ventilation door, and the production of the ventilation door will be carried out to remove rust and other work at the window, the purpose is to prevent the window from rusting, and the performance of the material will be reduced, so the original existing anti-theft door will be reduced to make its anti-theft performance.
