Time is safety

LIGNATUR sets new standards in fire protection. LIGNATUR is the first and only company with a European technical approval that defines the determination of the residual cross-section for standard and acoustic elements. This means that the fire resistance according to Eurocode 5 (EN 1995-1 - 2) can be determined.

Explanation videos on fire resistance

The fire resistance is the time in minutes during which a component must fulfil its functions – load-bearing capacity or room integrity – without restriction. It can be increased by suitable cross-section formats.

In the films, our consultants explain how it's done with LIGNATUR.

Fire resistance, fire behavior

With the constructional components dimensioned according to VKF fire protection application Nr. 15421 and ETA-11 / 0137, LIGNATUR elements reach fire resistances up to REI90. They can thus be classified in burning  behaviour group RF3 in Switzerland. In the ETA-11 / 0137 their burning behaviour is stated according to EN 13501-1 with D-s1, d0 (normal flammability – almost no smoke production, no dripping).

Fire stops in building components with fire compartments

Installation for building services can cause penetration in space-enclosing elements. Fire regulations define the requirements for the installations. Through appropriate measures, the space enclosure of the plane element must not be affected, but also a transmission of fire into the building element must be avoided over a sufficient period of time. Suitable products for this are available on the market.
