This article is intended to show how to recognize a fire door.
Usually, a sign is attached to a fire/fire door, which contains information about the fire protection category. Usually this sign is attached to the door frame or to the door (face side).
- Top: An Ü sign indicates a fire/fire door
- Bottom: The designation EI30, EI60 or EI90 provides information about the fire resistance of the door (i.e. how long the door will withstand fire in minutes)
If you are unsure, you can either consult floor plans or contact the responsible specialist or installer.
