Cavan-based Kingspan has been sharply criticised by survivors of the Grenfell Tower tragedy and UK politicians after becoming an official team partner of a leading Formula One Team.
The partnership will see Kingspan chair Mercedes-AMG Petronas' new Sustainability Working Group.
Kingspan says the partnership brings together companies that are "committed to a greener planet" and have each set "ambitious targets for the future".
However, the partnership has been criticised by some, with UK Minister Michael Gove saying he's "deeply disappointed" that the F1 team is "accepting sponsorship from cladding firm Kingspan while the Grenfell Inquiry is ongoing".
The Grenfell Tower Inquiry was created to examine the circumstances leading up to and surrounding the fire at Grenfell Tower on the night of 14 June 2017, which killed 72 people.
Mr Gove added that he will "be writing to Mercedes to ask them to reconsider" and that "the Grenfell community deserves better".
Meanwhile, Grenfell United, a group made up of the families of victims and survivors of the fire, said news of the partnership "shattered" them.
Grenfell United said Kingspan is an "immoral company, focused solely on profit with a total disregard for human life".
In a statement to Northern Sound News, Kingspan said it "supports the vitally important work of the Inquiry to determine what went wrong and why".
The statement added that Kingspan "played no role in the design of the cladding system used on Grenfell Tower, where its K15 product constituted approximately 5 per cent of the insulation purchased for use".
The spokesperson said "it was used as a substitute product without Kingspan's knowledge in a system that was not compliant with the buildings regulations."
In response to the criticism, Mercedes-AMG Petronas' Team Principal Toto Wolff apologised for "any additional hurt" the partnership has caused.
He added that Mercedes-AMG Petronas "engaged with Kingspan in-depth to understand what role their products played in what happened in Grenfell".
Mr Wolff thanked Grenfell United for "the offer to meet in person" to allow him to "learn and understand better".
