It reflected a deliberate strategy to continue selling Reynobond 55 PE in the UK based on a statement about its fire performance that it knew to be false Grenfell Inquiry report's findings on cladding manufacturer Arconic By summer 2011, Arconic was “well aware that Reynobond 55 PE cassette form performed much worse in a fire and was considerably more dangerous than in riveted form” but was “determined to exploit what it saw as weak regulatory regimes in certain countries to sell it in cassette form “including for use on residential buildings”. But the report found that Kingspan “knowingly created a “false market in insulation” from 2005 onwards for use on buildings over 18 metres tall by claiming its K15 product had been part of a system that had been successfully tested under the BS 8414 cladding fire safety test, meaning it could be used in the wall of any building of that height regardless of its design or other components. As Kingspan knew, K15 could not honestly be sold as suitable for use in the external walls of buildings over 18 metres in height generally, but that is what it had succeeded in doing for many years Grenfell Inquiry report The inquiry branded this a “false claim”, adding: “As Kingspan knew, K15 could not honestly be sold as suitable for use in the external walls of buildings over 18 metres in height generally, but that is what it had succeeded in doing for many years.” Kingspan relied on the results of a single cladding fire safety test performed in 2005, on a system whose components were not representative of a typical external wall, the report said, and found that the firm continued to rely on that test despite changing the composition of K15 in 2006.
