Fire doors play a decisive role in the safety of buildings. But what exactly is behind this term and which classifications such as T30, T60 or T90 are relevant? In this article, we explain the basics of fire doors.
What is a fire door?
A fire door is a special door designed to prevent the spread of smoke and fire in a building in the event of a fire. It therefore fulfils a crucial safety function by acting as a barrier and protecting important escape and rescue routes.
Fire doors are made of various materials such as steel, wood or glass. They are designed to withstand a fire load for a certain period of time. Consequently, their construction and properties are categorised into different fire protection classes.
What does fire door T30, T60 and T90 mean?
The classification of a fire door as T30, T60 or T90 indicates how long the door can withstand a fire before it burns out or loses its function.
- T30: The door can withstand a normal fire for at least 30 minutes. It is considered fire-resistant.
- T60: The door can withstand a normal fire for at least 60 minutes. It is classed as highly fire-resistant.
- T90: The door can withstand a normal fire for at least 90 minutes. It is considered fire-resistant
The higher the number, the higher the fire resistance of the door.
What does FSA mean for fire protection doors?
FSA stands for ‘hold-open systems’. These make it possible to keep fire doors open during normal operation without impairing the protective function in the event of a fire. Hold-open systems therefore close fire doors automatically when required.
