It's not good to change the door, that's really hehe.
It is necessary, not because of the safety issue, but because the door is thick, there will be no resonance.
It depends on which one you are more interested in and which one is more useful.
You should take a look at the quality of the security door, and if it's too bad, it's better to replace it. My previous anti-theft door skin was too thin, there were many card doors, and the doors were deformed, and the back was replaced with an Aeburg door, which felt more face-saving, because it looked high-grade. At first glance, it is a high-end route.
Generally, as long as the seam is not large, there is no need to plug the joints with cement, fix it, and make a styrofoam to live.
The developer's "door-to-door dry balance" should be changed if it is correct or lost?
