when was the cladding put on grenfell tower
Grenfell Tower fire As part of the project, in 2015–2016, the concrete structure received new windows and new aluminium composite rainscreen cladding, in part to improve the appearance of the building.[41] Two types were used: Arconic's Reynobond PE, which consists of two, coil-coated, aluminium sheets that are fusion bonded to both sides of a polyethylene core; and Reynolux aluminium sheets. Beneath these, and fixed to the outside of the walls of the flats, was Celotex RS5000 PIR thermal insulation.[42][43][44] The work was carried out by Harley Facades of Crowborough, East Sussex, at a cost of £2.6 million.[45]
