'A typo' in an official fire safety report meant a component used in the cladding system of Grenfell Tower was listed as burning slower than it had in tests, an inquiry has heard. Studies had shown it took just five minutes for flames to climb four metres up a cladding rig built to test the cladding component. The material, Kingspan's Kooltherm K15 product, was a component of the insulation later used in Grenfell Tower's cladding system. The majority of the insulation used in cladding the west London tower block was made by Kingspan's rival firm Celotex. Philip Clark, BRE's former cladding test chief supervisor and author of the 2005 report told Wednesday's hearing that the error 'should have been corrected'.
