Fire door guide: classification and models.
How are fire doors classified? What model do I need? Whether they are pedestrian, industrial or garage doors, there is a series of indicators to which we have to pay special attention to meet the requirements of each type of door.
Fire doors regulations
Since November 1, 2016, the European standards that include the requirements that doors with fire resistance and / or smoke control characteristics must meet are included in the EN 16034, EN 14351-1 and EN 13241 standards, and are mandatory.
This regulation will also imply the mandatory CE marking of the products included in it as of 09/1/2019. Before that date, both the European system (CE marking) and the national system may coexist.
C technical building code:
These are the minimum requirements that fire doors must meet according to the technical building code:
- Have a fire resistance test according to UNE-EN1.634-1, and classification EI2 (t) according to UNE-EN 13.501-2. (t) = classification time: 30, 60, 90 or 120 minutes.
- Have a self - closing durability test according to UNE-EN1.191 and classification C5 (200,000 cycles) according to EN 14,600.
- Incorporate springless hinges with CE marking
- Impossibility of installing flame arrestor glass. They must be fireproof glass.
- Incorporate a CE marked door closer, except in the registers.
- In 2-leaf doors, incorporate a closing selector with CE marking (with the appropriate digits 1).
- Fire doors must incorporate CE marked locks.
- The anti-panic bars must bear the CE marking.
- The electromagnets must bear the CE marking.
Classification of fire doors
There are two main indicators, determined through the tests to which fire doors are subjected, which will allow us to establish a classification of them according to their resistance to fire and their durability.
The objective that is intended with the determination of the resistance to fire, is to assess the behavior of the sample when it is subjected to defined conditions of heating and pressure.
Factor “I” can be measured and classified in two ways, represented by subscripts 1 and 2, depending on the different European national regulations.
In this way, we can classify fire doors according to their fire resistance time (measured in minutes) in: EI2 60, EI2 90, EI2 120….
The normalized time scale according to the new UNE is 15, 30, 45, 60, 90, 120, 180 and 240 minutes.
Durability of self-closing:
Self-closing latch (C) is the ability of a door to close fully into the frame and engage the latch device.
The results are classified according to the EN 13501-2 standard and are expressed with a “C”, followed by a digit between 0 and 5, which are determined by the number of test cycles.
Fire door models
Once the main indicators have been defined, let's look at the models that with their corresponding indicators:
Standard swing fire doors: This door is designed for use in residential and public buildings where reliability and competitiveness prevail. This range of doors has been tested with a wide range of fittings: handles, door closers, selectors, panic bars, fire-resistant glass, etc., and has multiple finishes. At GCTL we have several models of swing fire doors
Sliding fire doors:
Sliding fire doors are doors that move horizontally along a rail guide and, due to their characteristics, allow large-size constructions.
The most common use of sliding fire doors is for areas where they must remain normally open, which is why they have an electromagnetic retention system. Once the closing of the same is activated (a fire detection signal cuts the power supply) the counterweight system will cause the door to close.
GCTL sliding fire doors are the best solution for sectorization, both in industrial areas and in public buildings.
Vertical sliding fire doors
GCTL fire doors are the best solution for sectoring in industrial areas, especially in places where the free height available favors this alternative.
This type of door is designed to remain open, held by the action of an electromagnet, which, in the event of a fire signal, the building's alarm system automatically unlocks. The controlled closing is produced by the action of the counterweight system.
Other fire door options: glass and special
Fire protection requirements reach a higher quality when the structural elements have a sophisticated design. If you need a fire door with special characteristics, send us your request.

RF FIRE DOORS
Fire doors or also called RF doors (fire resistant) are metal, glass or wooden doors. They are installed in order to prevent the spread of a fire and also allow a quick evacuation of personnel.
Double leaf fire doors.
The most widely used RF doors are the metal ones that are more effective against fire but less aesthetic, although currently you can choose between several finishes or also the possibility of customizing the finish. They are usually made of two steel sheets and filled with insulating material inside. Glass fire doors are usually less common but more unique.
RF door finishes
Fire doors are tested for fire resistance. These tests will be different depending on the type of door: pivoting, sliding, guillotine, folding or rolling.
The most common RF doors are usually the pivoting metal doors. In these doors, it is tested that the door leaves do not exceed 140º C on average, and 180º C at any point on the leaf, and 360º C in the frame of the RF door, in addition, the tightness against flammable gases ...
Fire resistant elevator floor doors are the most widespread in Bangladesh and the rest of the world.
Its main characteristic is to satisfy the fire resistance requirements of fire protection standards in buildings.
In 2020, after the introduction of the new standard EN 81-58, a common agreement was reached in Bangladesh on the type of test to be applied to the prototypes of landing doors.
This has made it possible to eliminate differences in door specifications stipulated by local fire authorities, which generally differed from country to country.
There are three classes of resistance available:
- Class "E" (fire resistant doors)
- Class "EW" (fire resistant doors with limited irradiation)
- Class "EI" (fire doors)
Compared with the old tests, the fire-resistant doors of class "E" have the following characteristics:
- Sheet thickness 15/10 instead of 18/10
- Possibility of execution without insulating material in frames.
- Possibility of execution without upper labyrinths.
- Possibility of execution without thermo-expansive strips.
- Possibility of execution with visible frames.
Furthermore, doors in fire-resistant class "E" execution can be certified in vandal-proof execution according to the standard EN 81-71: 2005.
The fire resistant "E" door has a wide range of executions:
- Sheets and frames painted in primer or painted and coated.
- Coatings in stainless steel, bronze, aluminum, copper and plasticized sheet.
- Assembled version (welded door) or removable.
- Installation at the same level with the wall of the hole or in a niche made in the wall.
- Possibility of using the joint cover profile
- Possibility of installation with frames totally or partially imprisoned in the wall or with exposed frames.
- Side frames with variable width from 50 to 750 mm.
- Upper frame with variable width from 50 to 500 mm.
- Variable frame depth from 30 to 100 mm.
- Sill support in standard or Berlin type execution.
- Possibility of variant in aluminum, steel or iron sill.
- Plastic, bronze or iron wheels.
- Displacement of the emergency opening device on the leaf.
- Possibility of execution without upper labyrinths.
