FIRE-RATED DOORS: EI STANDARD AND THEIR CRITICAL ROLE IN BUILDING SAFETY

In modern building design, beyond aesthetics and functionality, fire safety has become a top priority—especially in public buildings such as shopping malls, hotels, hospitals, and schools. Among key fire protection components, fire-rated doors play a crucial role in protecting lives during emergencies.

1. What Are Fire-Rated Doors? Their Role in Building Safety

Fire-rated doors are specially designed and manufactured using materials capable of withstanding fire, smoke, and heat for a specific duration. Their primary functions include:

• Preventing the spread of flames and smoke between areas

• Creating safe evacuation routes for building occupants

• Preserving the structural integrity of the building during a fire

2. What Is the EI Standard? Classification by Fire Resistance Level

The EI classification is defined by the European standard EN 13501, in which:

• E (Integrity): The door maintains its structural integrity—no cracks, breaks, or collapses, effectively preventing fire penetration

• I (Insulation): The door limits heat transfer—ensuring the non-fire side does not reach critical temperatures

Common EI ratings include:

• EI30: Fire resistance for 30 minutes

• EI60: Fire resistance for 60 minutes

• EI90: Fire resistance for 90 minutes

The appropriate EI rating should be selected based on the building type and the specific fire risk of each area.

3. Real-World Applications in Buildings

• Shopping centers: EI60 or EI90 doors at emergency exits and technical zones

• Hotels: EI30–EI60 doors in corridors and buffer zones

• Hospitals: EI60 and above for ensuring safe evacuation paths

• Schools and factories: At least EI60 in crowded or high-risk zones
