UK: Insulation and cladding companies have blamed each other in a public inquiry investigating the Grenfell Tower Fire that took place in 2017 that led to 72 deaths. During closing statements to the inquiry the Press Association reports that the legal representation for Ireland-based Kingspan said, "In its phase one report the inquiry concluded that the cladding system on Grenfell Tower did not comply with the building regulations and that the PE ACM [polyethylene cladding] manufactured by Arconic was the principal reason for the rapid fire spread." The lawyer went on to summarise that Kingspan’s Kooltherm K15 phenolic insulation product was safe when used appropriately and not relevant to the nature and speed of the spread of the fire in this instance.
In a written statement though Arconic blamed the cause of the fire upon the failure by those involved in the refurbishment of the tower in assessing the fire performance of the building materials used and their configuration. It added, "A failure which was in significant part the result of the efforts made by the manufacturers of the insulation, Celotex and Kingspan, to hide or downplay the combustible and hence (under the prevailing regulatory regime) non-compliant nature of their product, an awareness of which would otherwise and in any event have led inexorably to the choice and configuration of the components being re-visited and amended."
The majority of the insulation purchased for use in a refurbishment of Grenfell Tower prior to the fire in June 2017 was Celotex’s RS5000 polyisocyanurate foam (PIR) insulation board. However, Kingspan confirmed in July 2017 that a small amount of its Kooltherm K15 product had also been used without its knowledge and that it had no involvement in the design or specification of the refurbishment.
