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.

«I accompanied all of Lignatur’s fire tests. The engineers from Waldstatt have achieved another important goal with the development of the «REI60/El30 non-flammable». This was thus the first time that simple wood elements could be used in Switzerland in 5 and 6-storey buildings. I am convinced that this idea will catch on in Germany and the rest of Europe too. But we have already taken the next step in Switzerland – buildings up to an overall height of 30m with visible timber ceiling elements in a REI60 design.»

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).

Requirements for fire resistance

In multi-storey timber engineering, fire protection is possible based on multiple examined constructions and concepts up to high-rise constructions. This applies to all of Europe.

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.
