EN 1634-1 – Fire-resistant doors, windows and walls (E/I/W classification)
European test standard for fire resistance of protective structures
The EN 1634-1 standard specifies how doors, windows, shutters, and walls are tested under standardized fire conditions. This test measures:
- how quickly a structure ignites,
- how long it holds back the flames,
- how much heat or smoke can penetrate,
- and how long the element maintains its structural integrity.
Fire resistance is important for both personal safety and business continuity. A door or wall that slows down a fire creates valuable time for evacuation, intervention, and damage limitation, especially in critical areas such as technical rooms, data centers, public buildings, and industrial sites.
Classes available at Armatis:
Classifications according to EN 1634-1 / EN 13501-2
Fire resistance performance is expressed in three parameter::
E – Flame tightness
Protects against the passage of flames and smoke.
Prevents flame spread to adjacent spaces.
I – Thermal insulation
Indicates how well the element retains heat.
Prevents the temperature of the safe side from rising too quickly: important to prevent fire spread via heat radiation
W – Heat radiation
Measures the amount of heat radiation that penetrates the structure.
This class protects people and fire-sensitive materials behind the door or wall.
Time ratings: EI30 – EI60 – EI120
The classification is always linked to a time period that indicates how long the element guarantees its performance:
- EI30 → 30 minutes of protection
- EI60 → 60 minutes of protection
- EI120 → 120 minutes of protection
The higher the value, the longer the door, wall, or glass module will resit flames, heat and smoke.
Fire-resistant solutions at Armatis
Armatis applies fire-resistant solutions to:
- doors (security doors & technical fire doors)
- walls and compartments
- glass structures
All these elements can also be combined with burglar resistance (RC), bullet resistance (FB/BR), or blast resistance, depending on the building's risk profile.
Why fire resistance is important for your project
Fire-resistant certifications according to EN 1634-1 guarantees:
- correct evacuation and intervention time
- protection of ciritcal areas (IT, archive, vault, control room,…)
- compliance with legal and insurance requirements
- limitation of personal injury and business interruption
