The rapid spread of the Lacrosse building fire, which was sparked by a cigarette on an eighth-floor balcony and raced up 13 floors to the roof of the 21-storey building in 11 minutes, was blamed on flammable aluminium composite cladding that lined the exterior concrete walls.
The same type of cladding was installed on the Grenfell Tower in 2016, as part of a £10m renovation.
Aluminium composite panels have a polyethylene or plastic core and an aluminium coating. It is a cheap building material widely used worldwide to clad high-rise apartment buildings.
The local council is putting flammable plastic coatings on high rise buildings now?
