We chose a condominium that is currently under construction. The developer offers some special requests as catalog options for an additional fee. A secure front door to the condo is very important to us, especially since the condo is in an attic.
Standard door standard RC2 with mortise lock and 1-point locking.
For an additional fee (about 1,500 euros), it is possible to install a door of the RC3 standard. Among other things, it has a multi-point lock with 2 pivot bolts.
As far as I could find out, the RC3 standard has a few extra features (the door has to be thicker, have a latch, etc.), so the extra fee should be worth it, right?
Alternatively, I could, of course, choose the cheaper RC2 door and install a deadbolt. Perhaps someone can say something about this, which in general should be more secure. The RC4 door is not offered by the developer.
Regularly locking the door is more important than RC3 or RC4. RC2 will do just fine.
There is no such thing as tamper-proof; there is only locking. If you need it for a sense of security, do it. But then immediately do it with an automatic lockout. As a bonus, such a door has better soundproofing as well.
Since you are worried about it, upgrade to RC3.
You'll feel calmer and sleep better even on vacation. Buy a known brand door manufacturer's sign and stick it on the outside. The burglar will move on to the RC2 door.
Are you talking about the front door or the apartment door? For the front door to be a problem, the burglar has to get into the house first. I would bring it up in the homeowners association and get the front door secured accordingly.
I wouldn't waste money on that. The likelihood of someone breaking in is not that great, despite the series of burglaries the newspapers sometimes write about. Better yet, buy proper insurance that takes responsibility in the event of damage.
