Cladding believed to have been used on Grenfell Tower is banned in the US, it has emerged, amid revelations that it would have cost just £5,000 extra for the contractors to apply a fire-resistant version of panelling to the building.
[...]
A salesman for the US company Reynobond, which produces the panels, told The Times the type of panel believed to have been used on Grenfell Tower was banned on tall buildings in the US “because of the fire and smoke spread”.
He said the PE version is used for small commercial buildings and petrol stations, rather than for tower blocks or major public buildings such as hospitals, adding: “It’s because of the fire and smoke spread. The FR [variant] is fire-resistant. The PE is just plastic."
