Unlike standard doors, a fire door is manufactured to endure the spread of fire for a specific period of time. A typical fire door can withstand against fire for a minimum of 30 minutes. Such an ample time window allows for inhabitants inside a building to get out it.
Fire doors can either be of solid construction or made using a special core which is burns at a very slow pace. The doors can also be made using special seals that are fitted into either the door or frame
