Research since the Grenfell Tower tragedy, which killed 72 people in a London high-rise fire in June 2017, has failed to settle all the questions about building cladding and fire safety in the UK. Fire tests have triggered worries about another cladding material and raised questions about whether different tests should be considered similar sources of concern.
A year ago, the issues rose to new levels in the UK with the publication of a study by insurers who claimed that current fire safety measures were inadequate and failed to take account of numerous factors that contribute to the heat and spread of fire in buildings.
