Saw the pictures on the tv and something stroke me strait away- the gap between the cladding and the insulation and batons used for under the windows . Kingspan can resist fire with the foil, but the sides without- burns like hell.Celotex on the other hand has no chance standing against fire and was recommended by Mark Allen, technical director of Saint Gobain UK, which makes Celotex insulation, who is on the Building Regulations Advisory Committee (BRAC) .Zinc cladding originally proposed ,was replaced with an aluminium type, which was less fire resistant, saving nearly £300k.Do it cheap, do it twice! Wonder where have I heard that!
