Installation | Fire protection curtains

Areas of application
The textile fire and smoke protection curtains as well as smoke barriers are used to close wall or ceiling openings in the event of a fire. Their constructive structure and the use of different fabrics enable a wide range of applications as well as different protection goals or classifications and time classes. Housing and guide rails of the flexible systems fit almost invisibly into the building and offer a lot of design freedom for sophisticated architecture of open space concepts.

Classification

To dimension the steps, the fire curtain must remain effective as an integrity for a defined period of fire exposure according to the standard ISO time-temperature curve (ETK), while the passage of fire and smoke is prevented. However, since the heat is passed on, fire protection curtains may only be installed with an approved deviation or a relief from the building law. To improve fire protection, a water sprinkler system or an automatic fire extinguishing system can be installed.

The different levels of fire protection curtains are classified according to the product standard DIN EN 16034. The European classes according to DIN EN 13501-2 are:

  • E = integrity
  • EW = integrity with reduced heat radiation
  • EI = integrity with insulating effect (fire-retardant, highly fire-retardant and fire-resistant)

Advantages of fire protection curtains
In contrast to fire protection gates, fire protection curtains - also called textile fire protection - require less space. They are used as mobile fire protection barriers and visually blend in very well with the building. Fire curtains are therefore used in particular in public buildings, hotels, offices and department stores.

Fire protection curtains with a horizontal closing direction are installed in order to achieve a fire protection barrier between floors. They are mainly installed in buildings with atriums, free-standing stairs and open floor plans. If the fire protection curtain is not in use, it disappears rolled up or folded below the floor.

Installation
It is also possible to install fire protection curtains at an angle between 30 ° and 150 °. For example, open escape stairs can be shielded. By folding the fire curtain, closed corners can be placed. The fire-proof closure on the floor is ensured by an end strip with integrated spring elements.
