Fire protection

Fire protection is understood to mean all measures that prevent the development and spread of a fire and enable the rescue of people and animals as well as effective extinguishing work in the event of a fire. Flame spread and heat release divided into classes. The flammability increases from RF1 to class RF4.

- RF1 (no fire contribution);
- RF2 (low fire contribution);
- RF3 (permissible fire contribution);
- RF4 (inadmissible Fire contribution).

Components must retain their function (load-bearing capacity, smoke-tightness, prevention of fire spread through thermal radiation or heat conduction) for a specified duration in the event of fire.

The main performance criteria for determining fire resistance are

E for room closure
The room closure describes the ability to withstand a one-sided fire exposure in such a way that significant amounts of flames or hot gases do not contribute to the spread of the fire or adjacent materials on the side facing away from the fire.
< br> I for thermal insulation
Thermal insulation describes the ability of the component to withstand a one-sided fire load in such a way that a transfer occurs even if there is significant heat transfer to the side facing away from the fire of the fire is excluded.
