Fire doors play a crucial role in the safety of buildings. They prevent the spread of fire and give people present time to get to safety.
But how long does a fire door retain its function and what factors influence its longevity?
In this article, we look at the most important aspects that determine the functional and service life of a fire door.
How long does a fire door retain its function in the event of a fire?
A fire door retains its function for different lengths of time in the event of a fire. The fire resistance class of the fire door is decisive here. It is always indicated with the prefix “T” and a number indicating the minutes in steps of 30. Typical fire resistance classes are T30, T60 and T90.
Example: A fire door with the code number T30 can therefore withstand a fire for at least 30 minutes according to the standard temperature-time curve (ETK).
In practice, the actual functionality depends on various factors. On the one hand, regular maintenance of a fire door is crucial to ensure its long-term functionality. Damage to the seals, the closing mechanism or the surface can impair its effectiveness.
Secondly, the environmental conditions can also influence the service life of a fire door. Materials can wear out more quickly in particularly damp or chemically contaminated environments. Regular cleaning and protection against mechanical stress help to increase the service life.
In addition, some parts of a fire door, such as the seals or closing devices, can wear out over time. In most cases, however, these components can be replaced without having to replace the entire door. It is important to use only certified spare parts in order to comply with safety standards.
Overview of service life
Under optimum conditions and with regular maintenance, fire doors can remain functional for many years. Nevertheless, it is advisable to regularly check the condition and effectiveness of the doors. Replacement may be necessary if the condition of the door no longer meets current safety requirements.
If you want to be on the safe side, you should have the doors checked regularly by specialists and replace individual components if necessary.
