LONDON, U.K. – A damning report on a deadly 2017 London high-rise fire said Wednesday that decades of failures by government, regulators and industry turned Grenfell Tower into a “death trap” where 72 people lost their lives. The public inquiry concluded that there was no “single cause” of the tragedy, but said a combination of dishonest companies, weak or incompetent regulators and complacent government led the building to be covered in combustible cladding that led to the deadliest blaze on British soil since World War II. Grenfell Tower, built from concrete in the 1970s, had been refurbished with aluminum and polyethylene cladding — a layer of foam insulation topped by two sheets of aluminum sandwiched around a layer of polyethylene, a combustible plastic polymer that melts and drips on exposure to heat. The report said the companies that made the building’s cladding engaged in “systematic dishonesty,” manipulating safety tests to claim the material was safe.
