Replacing a front door in a block of flats.

[sheep1003]

Hello

I live on the first floor of a block of flats. My front door is completely inside (there is a main door to the communal hallway, then I'm upstairs, not on an open walkway).
I have permission to change the door and they have said it needs to be a 30 minute fire door, which I'm happy with.
The questions I would like to ask is would an internal fire door be sufficient or do I need to be looking at external ones only?
Also if I can get an internal door is there any features that I need to really look for?

Thank you.

An 'internal' fire door may not give you the physical security you need from a front door.
