UK: The British Rigid Urethane Foam Manufacturers’ Association (BRUFMA) has said that the materials tested so far by BRE Group, following the Grenfell fire in June 2017, do not meet building regulations and would never be recommended or approved for use by the members of BRUFMA in a real building.
The Department for Communities and Local Government (DCLG) has commissioned six BS 8414 tests using a combination of materials, including the make-up of the outer cladding system. The first aluminium composite material (ACM) cladding test, carried out by BRE combined an assembly of polyisocyanurate (PIR) insulation used in conjunction with an unmodified polyethylene filled ACM cladding panel. Both PIR foam and mineral wool are being tested with each cladding system.
BRUFMA described the situation as ‘worrying’ that a number of buildings have been identified with this combination, indicating a lack of compliance to existing rules and regulations. However, it has advised that all six tests should be completed satisfactorily before any analysis is drawn and remedial action is proposed by the government. It also highlighted that PIR insulation manufactured in the UK and Ireland that is recommended for use in high-rise buildings is tested with the BS 8414 fire test as part of a complete ventilated rainscreen system.
