Smoke protection

Preventing the spread of poisonous smoke gases

Fire not only produces flames but also smoke. Smoke is a gas that contains tiny particles which can be extremely toxic – just a few breaths of the odourless gas carbon monoxide or carbon dioxide can be fatal. If the smoke is particularly thick, it also contains a large number of particles. Some gases are not as obvious as the flames or smoke itself. Smoke control doors are therefore a legal requirement in public buildings. But they can also be used to prevent smoke poisoning in private settings.

Reliable smoke control doors with steel profile systems

Smoke control doors are never completely smoke-tight. The permissible amount of leakage, however, is limited – it is based either on the length of the gap or the element as a whole. Smoke control doors with steel profile systems provide reliable tightness, as the torsion-resistant material does not become warped. Smoke control doors made using our steel profile systems are characterised by reliable functionality and high durability.

Signs for insulated and non-insulated smoke control doors

Smoke control doors must be tested with regard to their performance properties and, in Germany, for example, they must be fitted with a non-flammable sign. In order to meet European smoke protection requirements, Jansen has had both non-insulated and insulated door systems tested for smoke protection. The tested and certified anti-finger-trap door can be used as a smoke protection door in a wide variety of situations.
