UK: An investigation by the BBC’s Panorama news program has alleged that a safety test for Celotex’s RS5000’s polyisocyanurate foam (PIR) insulation board product used extra fire retardant in safety tests. The programme believes that a different product was eventually sold to the public. It also accused the subsidiary of Saint-Gobain of mis-selling the insulation with misleading marketing.
Celotex said that it was unaware of this allegation and had not identified anything that would support it. It is investigating this allegation as a ‘matter of urgency.’ It added that it had not used any special formulation for a recent successful BS-8414 system test in May 2018 or Class 0 fire testing.
Celotex suspended supply of RS5000 PIR insulation board in June 2017 following its use as part of the rainscreen cladding system in the refurbishment of Grenfell Tower. The building had a fire in June 2017 that killed 72 people.
