6.1 – Ventilated façade stratigraphy – 5. Protection against the spread of fire on ventilated façades 359 Projecting metal fire barrier A projecting fire barrier prevents the propagation of fire within the cavity and, thanks to the projection fromthe cladding, it limits the propagation of flames to the upper floors. According to the OEFHF AUSTRIA regulation and based on studies carried out, detailed analyses have been developed to achieve the protection objectives. Example of the construction of a fire barrier with a cladding of noncombustible material (titanium-zinc zintek®) at the internal corner of the façade Projecting fire barrier made of galvanized steel sheet or stainless-steel sheet thickness ≥ 1.0 mm cladded with zintek® a ≥ 100 ≥ 100 ≥ 200 ≥ 200 > 1,000 < 1,000 ≥ 500 A – projection of the metal fire barrier from the façade cladding with the function of protecting against the spread of flames, to be defined in the fire protection project EXCERPT
