Fireproof doors type REI

The R.E.I. classification is an acronym that indicates:
R     Resistance, mechanical ability of a material to resist fire
E     Tightness, i.e. it does not allow flames, vapors and gases to pass through to the unexposed side
I      Thermal insulation, i.e. the ability to insulate from heat

The figures that normally accompany this acronym indicate the minutes for which the characteristics of the structures or fire protection devices remain unchanged in the presence of a fire; beyond this period, certified safety is no longer guaranteed.

Fire doors must be marked on both sides with a UNI EN ISO 7010-F007 sign, showing the message “Fire door keep closed” or “Automatic closing fire door” if equipped with an electromagnetic stop on opening.
