Kingspan is one of the Republic of Ireland’s biggest businesses and sponsors the Ulster rugby team, who announced in January that their association with the company will end in June 2025.
Kingspan has also been the headline sponsor of the Cavan GAA county football team since 1995.
A small amount of a Kingspan insulation product, Kooltherm K15, which was used on the building, was not the reason for the fire.
The main cause was the tower’s cladding, which did not comply with building regulations and allowed flames to spread rapidly.
However, the inquiry’s final report sets out a “path to disaster” stretching back to the 1990s and looked at the broader conduct of the construction industry.
It found Kingspan “knowingly created a false market in insulation” from 2005 onwards for use on buildings over 18m tall.
