Fire doors

[TaylorBlake]

I've got nice 35mm oak doors but part of planning says i need to replace them with fire Doors. It's a shame but has to be done.
The new doors will be 44mm and the door jams are replaced. Will this leave a gap on the gripper? Do they also need replacing?

Unfortunately, I don’t know anything about how to install doors professionally. Therefore, you most likely need to seek help from specialists in this field.

I would replace the gripper as well, but it's up to you

Unfortunately, I don’t know anything about how to install doors professionally. Therefore, you most likely need to seek help from specialists in this field. You can also watch educational videos on YouTube. I replaced my old wooden doors with https://doordesignlab.com/front-entry-steel-appartment-metal-exterior-prehung-doors.html. Btw, you will be able to agree with the fire service that the cut of your doors is safe. After all, many people manage to find a common language with public services.
