Executives who sold combustible insulation for use on Grenfell Tower perpetrated a “fraud on the market” by rigging a fire test and making “misleading” claims about it, a public inquiry has heard.
Celotex, a subsidiary of the French construction materials company Saint-Gobain, behaved in a “completely unethical” way, admitted Jonathan Roper, a former assistant product manager.
