A second Aluminium Composite Material cladding system has passed government fire safety tests.

The system, which uses PIR solid foam insulation, has passed tests by the Building Research Establishment (BRE) set up in the wake of the Grenfell Tower tragedy.

The results show that ACM cladding with a limited combustibility filler (category 1 in screening tests) with PIR foam insulation can be compliant when installed and maintained properly.


The Government said while is has not been informed of any buildings over 18 metres in England using this particular combination of materials in their wall system, "it could offer a possible solution for some buildings with other cladding systems which have been identified as a fire hazard through previous large-scale tests".

"The clear advice from the Expert Panel remains that building owners need to continue to take professional advice regarding remedial work that takes into account the specific circumstances of their building," the Government said.
