Fire resistant doors

Everything you need to know about fire door regulations

The fire performance of a door or door block is defined by its ability to withstand fire for a specified period of time. The result is fire ratings obtained during tests carried out by approved laboratories according to standardized protocols.

E: Fire tightness

It is the ability of a building element with a compartmentalization function to withstand exposure to fire on one side only without transmission to the unexposed side due to the passage of significant quantities of flames or hot gases from the fire to the unexposed side.
They can cause either the surface not exposed to the fire to be ignited or of a material adjacent to this surface.

W: Radiation Limitation

Radiation limitation is the ability of a building element - when exposed to fire, on one side only - to reduce the spread of fire due to radiation, either through the element or from the side not exposed to surrounding materials.

The main objective of an EW classified door is to guarantee the impermeability to flames from the burnt room to the protected room and to minimize the effects of radiation (Radiation < 15 kW/m²).

Radiation example

Flux (kW/m²)	Conséquences
240	Rayonnement d'un feu intense (1150°C)
150	Rayonnement d'un feu moyen (1000°C)
100	Témpérature de 100°C dans 10 cm de beton pendant 3 heures
27	Ignition spontanée du bois en 40 s
5	Flux minimal létal en 60 s
2,9	Flux minimal létal en 120 s
1	Rayonnement solaire en zone équatoriale

I: Thermal insulation

It is the ability of the building element to withstand exposure to fire on one side only without transmitting it as a result of significant heat transfer from the exposed side to the unexposed side. Transmission must be limited so as not to ignite the unexposed surface or any material in its immediate vicinity (always used in addition to an E classification).

The particular case of door blocks

In the particular case of door blocks, one of the following two options for thermal insulation criteria must be used:

EI₁: Door units that benefit from an EI₁ classification can be used unconditionally.
EI₂ : Door units that benefit from an EI2 classification may be used provided that the walls and wall coverings adjacent to the door blocks are classified at least M1 or B-S3-d0 over a distance of 100 mm from the outer edge of the frame.

These performances are expressed in minutes.

Fire resistant doors classification

Performance is expressed in minutes. Thus, a door classified as EI 60 is a fire door that remains stable in a fire for at least one hour.

All our fire resistant doors:
Fireproof doors, fire doors, waterproof fire doors

Fire prevention is based on a combination of best practices, compliance with standards and the use of appropriate equipment, such as fire doors. The installation of doors that comply with current standards is essential to limit the spread of flames and ensure the safety of sensitive sites. Baumert has a wide range of doors but also fire-resistant partitions and to the flames as well as multi-required technical doors to secure your critical infrastructures against natural, biological or terrorist risks.
