UK: Celotex says that a rainscreen cladding system using its RS5000 polyisocyanurate foam (PIR) insulation board product has passed the BS 8414:2 safety test. The insulation producer previously announced in January 2018 that it had found errors between a previous test and the description of the system in the report of the test. It added that the rainscreen cladding system conformed to the BR 135 fire test. It is now notifying the relevant bodies and is contacting its customers about results of this latest test.
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 71 people. The suspension remains in place.
