UK: Celotex has stopped supplying its RS5000 polyisocyanurate foam (PIR) insulation board product in rainscreen cladding systems for buildings over 18m tall. The decision is a temporary one whilst an investigation into the Grenfell Tower fire continues. The subsidiary of Saint-Gobain previously confirmed that its product was purchased for use in a refurbishment project at the building. The fire is believed to have killed 79 people.
The insulation producer said that safety testing had been undertaken on its RS5000 product as part of a ‘particular’ rainscreen cladding system. It added that, “…any changes to components of the cladding system or construction methods used need to be considered by the relevant building designer.”
The decision by Celotex follows an announcement by the Metropolitan Police that insulation samples collected from Grenfell Tower combusted quickly in tests. The authorities are examining aluminium composite tiles, the insulation behind it and how these tiles were fixed to the building as well as how they were installed. The aluminium composite tiles have also failed initial safety tests.
