(help)They confirm that almost £300,000 was cut from the cost of the cladding system used on Grenfell Tower by changing from zinc to aluminium as part of what was described internally as a "value engineering process". Zinc panels with a fire retardant core were replaced by cheaper aluminium panels with a core that has since proved combustible in government tests.
