8 LONDON GRENFELL TOWER (JUNE 2017) the use of the flammable cladding being blamed for spreading the fire that killed at least 70+ people. Barry Turner, director of technical policy at Local Authority Building Control, which represents council building control teams in England and Wales, said: What we need to know is what was inspected. You can go on site 16 times but not necessarily see everything you need to see. They may have inspected the fixings, the fire barrier and the cavity, which are equally important but are useless if you put a flammable material on the front. FS Inspection 8

9 CURTAIN WALL / EXTERNAL FACADE Curtain wall materials shall be non-combustible, in accordance to BS-EN : 2007 (Class A1); BS 476 Part 4. Perimeter joint shall be sealed up to form smoke and fire barrier in accordance to BS EN 1364 Part 3 or Part 4 and BS EN , respectively. Non-combustible FRR and smoke barrier FS Inspection 9

10 COMBUSTIBILITY V.S. FIRE RESISTANCE Non-combustibility: Material characteristic Test standard: BS 476 Part 4 Non-combustibility test for materials Limited combustibility : BS 476 Part 7 Method of test to determine the classification of the surface spread of flame of products Materials of non-combustible DO NOT mean they are fire resistance within a given period. For example, a piece of aluminum foil! Fire resistance: System Characteristic : openings + penetrant + firestop sealing Test standard: Linear joint: BS EN or Penetration seal: BS EN ; BS 476 Part 20.
