Deborah Berger says she was shocked by firm’s approach to test three years before blaze
An executive at the manufacturer of foam insulation that burned on Grenfell Tower was so shocked that the firm had set up a fire test to play down the material’s potential combustibility that she scrawled “WTF?” in the margin of the test report, an inquiry has heard.
Deborah Berger, a product manager at Celotex, told the Grenfell public inquiry that almost three years before the 2017 disaster, colleagues alerted her that a safety test had been rigged with fire-retardant panels to boost the insulation’s fire performance, but the modifications were left out of marketing literature used by architects and specifiers.
