Here is Jonathan Roome, the former specification manager at Celotex, admitting the firm's marketing of the insulation product used on Grenfell was 'misleading' when it said it was 'suitable for use' on tall buildings
A little breakdown:
- RS5000 (used on Grenfell) passed a large-scale test as part of a wall made from cement fibre panels in 2014.
- This meant it was acceptable 𝐨𝐧𝐥𝐲 for walls of tall buildings made in exactly the same way (cement fibre panels)
- RS5000 (used on Grenfell) passed a large-scale test as part of a wall made from cement fibre panels in 2014.
- This meant it was acceptable 𝐨𝐧𝐥𝐲 for walls of tall buildings made in exactly the same way (cement fibre panels)
- But Celotex then went ahead and marketed it as "therefore suitable for use on buildings above 18m", no cavaet. It was used in many combinations, including the combustible ACM panels on Grenfell Tower
- The 2014 test has since been retracted for irregulaties including the undeclared use of fire resisting boards around the temperature monitors which recorded pass/fail.
- BONUS: it's actually still being advertised in that way on some websites (although it has actually been withdrawn from sale) (yes I've tried buying some to check) insulation-online.com/celotex-rs5000…
