abstract="Four reduced-height (5 m) BS 8414-1 façade flammability tests were conducted, three  having mineral-filled aluminium composite material (ACM-A2) with polyisocyanurate  (PIR) and phenolic (PF) foam and stone wool (SW) insulation, the fourth having  polyethylene-filled ACM (ACM-PE) with PIR insulation. Each façade was constructed  from a commercial façade engineer's design, and built by practising façade  installers. The ACM-PE/PIR façade burnt so ferociously it was extinguished after  13.5 min, for safety. The three ACM-A2 cladding panels lost their structural  integrity, and melted away from the test wall, whereupon around 40% of both the  combustible PIR and PF insulation burnt and contributed to the fire spread. This  demonstrates why all façade products must be non-combustible, not just the outer  panels. For the three ACM-A2 tests, while the temperature in front of the cavity was  independent of the insulation, the temperatures within it varied greatly, depending  on the insulation. The system using PF/A2 allowed fire to break through to the  cavity first, as seen by a sharp increase in temperature after 17 min. For PIR/A2,  the temperature increased sharply at 22 minutes, as the panel started to fall away  from the wall. For SW/A2, no rapid temperature rise was observed.<p /> <p>Language: en</p>",
