137 Kingspan and Celotex

Former staff from Kingspan, the manufacturer of an insulation product used on Grenfell Tower gave evidence this week.

Technical Project Lead Ivor Meredith, admitted he was involved in a deliberate calculated deceit carried out by the company – aimed at achieving the best possible sales for its insulation products.

Only a month ago Kingspan withdrew three large scale fire test reports after accepting the product tested did not represent what they were selling.
