The final test was of a wall cladding system consisting of aluminium composite material (ACM) cladding with a limited combustibility filler (category 1 in screening tests) with stone wool insulation. It passed.
The government鈥檚 expert panel said that the results showed that this combination of materials could be compliant with building regulations guidance when installed and maintained properly. While government has not been informed of any tall buildings over 18 metres in England using this particular combination of materials in their wall system, but it could offer a possible solution for some buildings with other cladding systems that have been identified as a fire hazard through the previous large-scale tests.
