Grenfell: Further cladding checks to be undertaken after 190 samples fail fire test

More urgent testing is to be undertaken on building cladding in the wake of the Grenfell Tower fire after samples sent in from 190 tower blocks across the country failed fire safety tests.

According to the Department for Communities and Local Government (DCLG), who have been carrying out the testing, experts will look at how different varieties of cladding insulation with different types of Aluminium Composite Material panels react in a fire as part of the extended testing.

The new tests will not require any new samples from buildings that have already sent them in.

It comes after 100% of the samples tested so far failed combustibility tests prompting an independent expert safety panel to recommend further tests be carried out.

Initial testing was rolled out after the Grenfell blaze in which at least 80 people died last month.

The additional large-scale testing will involve the construction of a building 30ft (9m) high which has a demonstration wall with a complete cladding system that will be subjected to conditions that replicate "a severe fire" and comes after concerns were raised that material was being tested too severely.

It is hoped the results will be able to help landlords make decisions about any further actions they may need to take to ensure buildings they have responsibility for are safe.

The announcement of further testing comes the day after police confirmed that the "last of the visible human remains" have been recovered from Grenfell Tower wreckage.
