Fire Doors

Fire Doors

A REI or EI door (fire door) is a door that has the ability to isolate the flames in case of fire thanks to its high fire resistance. It is therefore used as part of a passive protection system, to reduce the spread of flames or smoke between compartments and to ensure a safe exit from a building.

Sebino Fire and Security also proposes the use of certified fire doors in case of an integrated fire system.

To be considered a fire door, a door must meet two fundamental characteristics:

• Self-closing: the door shall self-close through devices such as spring hinges, door closers or counterweights in case of sliding doors.
• The Fire resistance of a closing element is expressed with an interval in minutes, during which the door or window retains its sealing and / or thermal insulation properties.

There are different regulations that set the classification of fire doors:

• European standard EN 16034
• Specific legislation for each country, for Italy it is UNI 9723

The European and Italian regulations are very similar: they have a similar classification that is expressed as follows (“EI” for EN 16034, “REI” for UNI 9723):

• Resistance: the capacity of an element, which must not be affected in the event of a fire (not applicable for fire doors, removed from the European legislation).
• Airtightness: the ability to retain fire. It does not mean that the door is sealed, as common sense suggests.
• Thermal insulation: the ability to reduce the transmission of heat to the face not exposed to the fire.
