Grenfell: Construction debris ‘jammed essential fire control switch’
Construction dust and debris generated during the refurbishment of Grenfell Tower may have contaminated an “essential” fire control switch.
A 2008 certificate issued by the British Board of Agrément (BBA) for Kingspan K15 insulation was based on data “extrapolated” from fire test reports on similar Kingspan phenolic products, some of which were 15 years old, in a “basic failure of due diligence” the Grenfell Tower Inquiry has heard.
A marketing manager at Arconic, the company that manufactured the combustible Reynobond PE 55 cladding used on Grenfell Tower, received a “very high shock” after attending a 2007 presentation warning of the combustibility of polyethylene-cored (PE) ACM cladding, the Grenfell Tower Inquiry has heard.
A BRE director does not recall the organisation following up on a “wholly inaccurate” certificate issued by Herefordshire LABC that gave automatic acceptance for cladding systems employing Kingspan’s combustible K15 insulation on buildings over 18m in height.
