Fire rated door classification and model selection guide
Whether pedestrian, industrial, or garage doors, there are several indicators to ensure fire-rated doors meet regulatory requirements.
Fire door regulations
Since November 1, 2016, European standards EN 16034, EN 14351-1, and EN 13241 have defined mandatory requirements for fire and/or smoke control doors.
From September 1, 2019, CE marking is mandatory. Before this, national and EU systems coexisted.
Fire-rated doors must comply with:
- Fire resistance test per UNE-EN 1634-1 and EI2 (t) classification per UNE-EN 13501-2, where (t) = 30, 60, 90, or 120 minutes.
- Self-closing durability test per UNE-EN 1191 C5 durability classification (200,000 cycles) under EN 14600.
Additional, they must meet the minimum requirements established by the Technical Building Code.
- Hinges (without spring)
- Fire-rated glazing only (no smoke-retardant glass)
- CE-marked door closers (except inspection hatches)
- CE-marked closing selectors (for double-leaf doors)
- CE-marked locks
- CE-marked panic bars
- CE-marked electromagnets
Automatic closing durability
The automatic closing classification (C) refers to a door’s ability to fully close into its frame and engage the locking mechanism.
Results are classified according to EN 13501-2 and are expressed with a “C” followed by a digit from 0 to 5, based on the number of cycles completed during the test.
| Category | Cycles |
|---|---|
| C5 | ≥ 200,000 |
| C4 | ≥ 100,000 |
| C3 | ≥ 50,000 |
| C2 | ≥ 10,000 |
| C1 | ≥ 500 |
| C0 | 1–499 |

Fire-resistant doors (en 1634-1)
The purpose of fire resistance testing is to evaluate the performance of a door sample when subjected to defined conditions of heat and pressure.
The “I” (insulation) factor can be measured and classified in two ways, indicated by subscripts 1 and 2, depending on national European regulations. Spanish regulations require classification according to EI2.
Based on this, fire-rated doors can be classified according to the duration of fire resistance (measured in minutes) as: EI2 60, EI2 90, EI2 120, etc.
The standardized time intervals under the updated UNE standard are: 15, 30, 45, 60, 90, 120, 180, and 240 minutes.

Fire rated door models
Once the main classification indicators have been defined, let’s take a look at the models offered by Kavidoors as certified manufacturers of fire-rated doors, along with their corresponding classifications:
Standard hinged fire doors
This door is designed for use in residential and public buildings, where reliability and cost-effectiveness are key priorities.
| Available classifications | Durability | Versions |
|---|---|---|
| EI2 45/60/90/120 | C5 | Single and double leaf |
This range of fire doors has been tested with a wide variety of hardware, including handles, door closers, closing selectors, panic bars, fire-resistant glazing, and more. A broad selection of finishes is also available. Within this model, we offer options such as double-leaf RF fire doors, large-size tunnel fire doors, and UL-certified fire doors compliant with ANSI-UL 10B standards.
Sliding fire doors
These fire-resistant doors move horizontally along a track system, allowing the construction of large openings. They are commonly used in areas that must remain open, thanks to an electromagnetic retention system. When a fire detection signal cuts off the power supply, a counterweight system ensures the automatic closing of the door.
They are an ideal solution for compartmentalization in industrial environments and public buildings, offering both safety and functionality.
Vertical sliding fire doors
Vertical fire doors are an excellent solution for compartmentalizing industrial areas, especially where available headroom makes this configuration the most efficient.
These doors are designed to remain open, held in place by an electromagnet. In the event of a fire signal, the building’s alarm system automatically releases the mechanism, and a counterweight system ensures controlled vertical closing.
| Available classifications | Versions |
|---|---|
| EI2 120 | Single leaf with vertical opening |

FAQs about fire-resistant doors
-
What is an industrial fire door and what is it used for?
It is a door designed to limit the spread of fire and smoke between sections of a building. Its purpose is to maintain compartmentation, protect evacuation routes and facilitate the intervention of emergency services.
-
What do EI30, EI60, EI90 and EI120 classifications mean?
The letter E indicates the door’s ability to maintain its integrity against fire and prevent the passage of flames and hot gases. The letter I indicates its thermal insulation capacity. The number represents the minutes for which these performance levels are maintained: 30, 60, 90 or 120 minutes.
-
What fire resistance does a door need for a building?
It depends on the building’s use, fire load, access location, compartment dimensions and the requirements of the fire protection project. The classification must be determined by the responsible technical professional in accordance with the applicable regulations.
-
What regulations and marking must a fire door have?
The door must have a valid fire resistance classification for the complete assembly, including the leaf, frame, guides, hardware and closing system. It must also include the documentation, identification and marking required for its marketing and installation.
-
Must an industrial fire door always remain closed?
It must remain closed whenever its compartmentation function requires it. It must not be blocked with objects, wedges or improvised elements that prevent it from closing correctly, as this may compromise compartmentation and the door’s intended operation in the event of fire.
-
Can a fire door stay open and close with the fire alarm?
Yes, provided it has an approved hold-open system connected to the fire detection or alarm system. When the signal is received, the system releases the door so that it closes automatically and restores compartmentation, preventing it from remaining open during an emergency.
-
How often should an industrial fire door be inspected?
It should be inspected periodically according to regulations, the manufacturer’s instructions and the conditions of use. In industrial facilities, the closing system, guides, seals, hardware, automation and safety devices should be checked regularly to detect possible faults and maintain the intended performance.

Who can install, repair or modify a fire door?
Installation and repairs must be carried out by qualified professionals who comply with the tested configuration and the manufacturer’s instructions. An unauthorised modification may reduce fire resistance or invalidate the certification, so changes that alter the characteristics of the assembly should not be made.
-
Can a damaged fire door be repaired?
It depends on the extent of the damage and whether the repair can preserve the certified performance. Minor adjustments or replacement of authorised components may be possible, but a warped, perforated or severely damaged door leaf may need to be replaced to ensure that the assembly maintains its certified fire resistance.
-
How much does an industrial fire door cost installed?
The price depends on the dimensions, fire resistance classification, opening system, automation, safety devices and installation conditions. To prepare an accurate quotation, the opening, intended use and specific requirements established in the project must be reviewed.
