Questions over the government’s testing regime for aluminium composite panels continued to grow with one expert warning: “[It] doesn’t necessarily reflect what is going to happen on a building.”
The government has given limited information about how the tests on cladding samples are being carried out by the Building Research Establishment. The Department for
Communities and Local Government said it was undertaking combustibility tests on core materials, but experts have warned that cladding systems also need to be tested as a whole, including insulation materials and design features such as fire breaks.
