Latest large-scale government fire safety test completed

The latest in the government’s series of fire safety tests of cladding and insulation combinations has been completed by the Building Research Establishment (BRE).

The test was of a wall cladding system consisting of Aluminium Composite Material (ACM) cladding with a fire retardant polyethylene filler (category 2 in screening tests) with phenolic foam insulation.

The government’s expert panel advises that the results show this combination of materials does not meet current Building Regulations guidance.

Initial screening tests have identified 22 buildings over 18 metres tall in England known to have this combination of cladding. Cladding samples from each of these buildings had already failed early tests conducted by BRE and owners were sent government advice detailing the immediate interim safety measures that needed to be taken. Appropriate measures have been put in place for all 22 buildings.

Government has also provided these building owners with additional detailed advice setting out the actions they need to take to ensure the safety of residents. Government is working closely with the owners to make sure this advice is being followed.

The large scale tests allow experts to better understand how different types of cladding panels behave with different types of insulation in a fire. The results of the first five tests have already been published.
