Fire Resistance Classes
Firebreather™ technology is approved for fire resistance EI30, EI60 and EI90.
E = Integrity.
I = Insulation.
For a building part with fire-separating function, integrity (E) is defined as the building component's ability to withstand the fire on one side, without the fire passing through, due to the penetration of flames and hot gases.
Insulation (I) means that construction should limit the temperature rise on unexposed side so that it is at most 140 ° C in average and never above 180 ° C at one point.
In addition, we have the only products with instant flame stop.
