My first impression of this fire, was that it was burning on the outside, and having just been refurbished ? I think heads are going to roll on this one.
Fire safety at Grenfell Tower placed under review last year
Residents warned of ‘dangerous living conditions’ as owner ordered changes to way it handled fire risk in its properties.
"The block underwent a £10.3m renovation that was completed in May 2016. In January that year, Grenfell Action Group raised concern about the single emergency exit to the building in 2016, warning that if that exit were to become blocked in a fire, people would be trapped inside.
Renovations also included the addition of insulated exterior cladding and double-glazed windows to the reinforced concrete building, as well as a communal heating system.
The building works were criticised by the Grenfell Action Group, which said the installation of new water heaters in the hallways of many of the flats made the already tight access even more cramped.
The 1970s building was clad with a system of polyester powder-coated aluminium rain-screen panels, many of which appeared to be burning strongly during the blaze. It was installed at a cost of £2.6m by specialist facades contractor Harley Facades Limited."
