October of this year. On October 1, 2018, the government confirmed that flammable materials will be prohibited on the outside walls of high-rise residential structures. The funds will be used to demolish and replace the ACM cladding on their high-rise social housing complexes. This comes after three years of warnings from scientists about the potential for disaster if action was not taken. ACM is an abbreviation for Aluminium Composite Material. It's a type of cladding used on high-rise buildings that contains aluminum foil and plastic fibers. The problem is that it's very combustible and can burn for hours before falling to the ground. In addition, remnants of burned out fiberglass have been found in the soil near buildings that had their cladding damaged during the London fire. This has caused concerns about other types of material being tested or used instead. The government has announced plans to spend $140 million (100 million euros) over the next three years on removing the ACM cladding from high-rise social housing complexes across London. So far, 32 buildings have been identified for replacement. These buildings were built between 1967 and 1976 and are within the City of London limit. Replacement panels will be made of glass or steel. It's estimated that there are around 10,000 high-rise buildings in London that would need replacing the cladding on their exterior walls.
