In accordance with the requirements of the building regulations as to buildings and their location, fire-resisting door and windows that are to be installed in the openings of vertical separating elements in a building should be designed and constructed in such a way, that in case of fire:
- Prevent fire from spreading
- Limit the spread of fire and smoke in the building to other rooms and zones,
- Limit the spread of fire to other buildings,
- Allow the evacuation of building occupants by limiting the level of heat radiation, - ensure safety and facilitate the operation of emergency crews
The required fire resistance rating for partitions is determined by the provisions in force in the respective countries, and can be dependent on the fire resistance class, to which the building is suited. This is shown in the table below:
Fire resistive rating (Building) |
Yangın direnci değeri (partition wall) |
| A | EI 60 |
| B | EI 30 |
| C | EI 15 |
| D | - |
| E | - |
