Had a 10-odd tweet thread giving a customary lunchtime update from the inquiry, but had my six-month-old on my lap and he leaned over and clicked the mouse and it all disappeared
Realise this is the lockdown equivalent of "the dog ate my homework" but there we go.
Anyway - very brief version of what I was going to say is that this morning we've been hearing from this Tony Millichap, head of technical at Kingspan from 2010-2015
He's been grilled on his knowledge of K15, its testing and certificates and advice Kingspan gave to the market about its suitability for high rises. Built towards the QC suggesting that this advice was "entirely misleading" which he denied
In particular, we saw this proposed letter, which he edited and signed off which told architects working for Bellway that a tower it was planning to build with zinc cladding could incorporate K15
Note the use of the phrase "should be accepted by your Local Authority Building Control". He had previously said Kingspan wouldn't give specific advice about whether or not systems complied, as this was a matter for the project team
"Aren't you giving advice here on the compliance of the construction system proposed on this building?" asks Kate Grange.
"We are offering an opinion," he replies. He had early said Kingspan could "influence" these decisions due to "absence of knowledge" in the industry
(He later swapped the word influence for inform).
Problem with this advice was that it was based on test of a cement fibre system and the zinc cladding proposed was entirely different. "The advice was utterly misleading given the test evidence you actually had," said Ms Grange
"I don't believe it was, I believe we were drawing parallels between the test evidence we had and offered opportunities for professionals to make that judgement".
Anyway, lots of other things were discussed, which you'll simply have to believe me on as they have fallen victim to the little one's intervention. Millichap carrying on after lunch.

Right so, today at the inquiry we filled in a new piece of the puzzle surrounding the government's failure to change regulations in time to stop Grenfell 🧵
We have known since 2018 that the key official responsible for Approved Document B (the guidance which covers fire safety) had attended an industry briefing on 2 July 2014, where very specific warnings were given about combustible insulation and cladding insidehousing.co.uk/news/news/gove…
(I know it's probably poor form to do the whole 'this was my scoop' thing, but this was my scoop)
Anyway, that meeting contained very clearly delivered warnings about the use of combustible ACM cladding and insulation on high rises. Here's what was said about insulation:
- Govt officials warned about use of Kingspan insulation on high rises in 2014
- Kingspan accused of "lying" to them about testing which had been carried out on new 'trial product' - not material actually on market
We saw important new emails today which show Brian Martin (the official in charge of Approved Document B) was specifically and clearly warned about the use of K15 on high rises in summer 2014
In July 2014, he wrote to the NHBC saying "allegedly" PIR insulation had been used on buildings above 18m in height and asking for info. I think this follows a meeting about cladding risks from the same month, which I obtained the minutes of in 2018 insidehousing.co.uk/news/news/gove…
Current Kingspan witness is boasting that the firm was a "thought-leader" in terms of the compliance of combustible materials for the walls of high rise buildings...
"We had quite a lot of input into influencing how this could be understood and interpretting the regulations as we saw them."
He says that the firm did this through "explaining the fundamentals" to professionals who called up to query where the insulation could be used
This sits against other witness evidence who have said they assumed the industry would understand when and where Kingspan's insulation could be used because they were experienced professionals - effectively downplaying the role of the firm.
Kingspan used pass on new 'trial product' to keep selling its insulation for high rises after a consultancy warned it would tell the industry it was not suitable in 2013, inquiry hears
Incidentally, this is Wintech, the self-same consultancy who were Kingspan was internally saying could "go fuck themselves... or we will sue the arse of them".
Among the only organisations emerging from this with any credit:
Following this emai Kingspan commissioned some new testing and after failing a few times it passed with a new system in July 2014. It began telling the market about this "good news". But unfortunately the pass was on a new trial product, not what was being sold.
Dr Malcolm Rochefort grilled over why Kingspan's insulation was not withdrawn from the market after tests showed a deteriorating fire performance
Much of this evidence has already been discussed over the last two weeks, but the inquiry has been asking Rochefort about the change in way of making its flagship insulation for high rises, K15, in 2006 and subsequent testing of that material
(Your regular reminder that a small quantity of K15 was used on Grenfell, but the product has been sold and installed for high rises for 15 years and is on hundreds, possibly thousands)
This morning we've seen that the former technical manager at Kingspan reacted to queries about the fire safety of its insulation by saying "they're getting me confused with someone who gives a damn" and "they can go fuck themselves".
It was among the insulation used on Grenfell.
He added in one email "imagine a fire running up this tower!!!!!!" and said "we will sue the arse off them" about a consultancy which was raising concerns.
Its use on high rises was justified on the basis of a test which was not representative of real world systems.
It was also justified based on testing which used an older version of the product, with the newer version burning like a "raging inferno" when tested. Kingspan did not release this information to the market. The insulation is currently on hundreds of high rises around the country
