Kingspan awaits conclusions of Grenfell Inquiry

• That Kingspan carried out its first large-scale fire test on K15 in 2005, which passed, but included the use of non-weatherproofed cement fibre cladding panels, which critics said could not be used on a real high-rise building

• Kingspan continued to use these test results to sell the material as appropriate for high-rise buildings, despite changing how K15 was produced and conducting a subsequent fire test on the product, which resulted in a “raging inferno”. The test’s result was described as shocking by the firm’s ex-technical director Ivor Meredith

• The firm’s technical manager, Philip Heath, sent an email to friends regarding a contractor’s concerns over the material’s use on high-rise buildings, saying he was being confused “for someone who gives a dam” and that he was “trying to think of a way out of this one, imagine a fire running up this tower! Any ideas?” Mr Heath told the inquiry he was in a dark place because of a friend’s terminal illness

• In 2007, the firm carried out fire tests only on the foil covering K15, using its interpretation of the testing guidance to claim the entire product had achieved a “Class 0” industry-best safety standard. The inquiry heard evidence of two company employees joking that it was “all lies mate” and “all we do is lie here”
