Can the types of cladding in the development be classified exactly? Where are these claddings? How much of the building needs re-cladding?

As far as we can establish, as there seems to be no industry standard definition of ACM (Aluminium Composite Material), we do NOT have Grenfell-type ACM. This is a thin pre-formed composite sheet (a fusion of polystyrene and metal). Islington Gates has a sandwich cladding of 0.5mm steel, 1mm Aluminium sandwiching 20mm of pink polystyrene insulation – the flammable core.
We also have timber cladding that is fire-retardant treated, but, like the metal cladding is not properly fire-stopped. The insurers insist we remove all fire risk cladding, metal and timber. Brick areas are not a risk.
