Final test results on ACM wall cladding systems published 31/08/2017 Labelled as Repairs, Regulation

We reported in the last edition of the ARCH Bulletin on the outcome of the large- scale fire tests and the results of the first 5 tests on various combinations of cladding systems.


The results of the two remaining large scale tests have now been published:


Test No 6 and the last in the series of tests to be published 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 was published on 25 August 2017 and has passed and meets current Building Regulations guidance. The government's expert panel advises that the results show that this combination of materials can be compliant 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, 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 series of large-scale tests initially included 6 combinations of cladding systems but on 8 August 2017, the government announced that on the advice of the Expert Panel it would undertake a further large-scale test of ACM with fire retardant polyethylene filler (category 2 in screening tests) with phenolic foam insulation.  The results of this seventh additional test of this type of wall cladding system were published on 21 August 2017 and the government's expert panel advises that the results show that the combination of materials used in the test does not meet current Building Regulations guidance.


Initial screening tests have identified 22 buildings over 18 metres tall in England known to have a combination of ACM with a fire-retardant polyethylene filler with phenolic foam insulation. Cladding samples from each of these buildings had already failed earlier combustibility tests conducted by BRE and their owners were sent government advice detailing the immediate interim safety measures that needed to be completed. The government say that appropriate measures have been put in place for all 22 of these buildings.


The results of all 7 large-scale tests are now available on the government website and the government has said it will shortly publish consolidated advice to landlords based on all 7 tests.
