Part 3
The testing and marketing of products (Chapters 15 – 29)
2.19 One very significant reason why Grenfell Tower came to be clad in combustible materials
was systematic dishonesty on the part of those who made and sold the rainscreen cladding
panels and insulation products. They engaged in deliberate and sustained strategies to
manipulate the testing processes, misrepresent test data and mislead the market. In the
case of the principal insulation product used on Grenfell Tower, Celotex RS5000, the
Building Research Establishment (BRE) was complicit in that strategy.
2.20 Those strategies succeeded partly because the certification bodies that provided assurance
to the market of the quality and characteristics of the products, the British Board of
Agrément (BBA) and Local Authority Building Control (LABC), failed to ensure that the
statements in their product certificates were accurate and based on test evidence.
UKAS, the body charged with oversight of the certification bodies, failed to apply proper
standards of monitoring and supervision.
