An unusual section of the inquiry where expert Paul Hyett and team assembled and disassembled a scale model of the cladding system on Grenfell - including their own 'indicative approach' which would have aligned with regulations
Much of what they showed is already known and has been discussed at quite a lot of length, but it was helpful to see it in this way. For example, we've heard a lot about how cavity barriers were not put directly around window openings...
... this shows exactly what was done. They are the grey horizontal lines cutting through the turquoise. You can see how far from the top and bottom of the window they are:
And we've heard a lot about how moving the window forward left a gap of c120mm which was stuffed with combustible insulation giving a potential route for fire to escape. Here is that gap (with the insulation removed). This is a closed window.
Hyett's team then showed a compliant design, with correctly positioned cavity barriers and non-combustible mineral wool insulation. That's on the left here:
He says it obtains a similar aesthetic, but you do end up with a slightly thicker wall:

Tomorrow could well be one of the most important days in the Grenfell Tower inquiry since it began two and a half years ago.
I appreciate minds are firmly elsewhere, but here's a quick thread of what's happening and why it matters:
We are about to begin Module 2 of Phase 2. This section will look at 'the testing, classification, certification and marketing' of the deadly materials fitted to the walls of the tower. That sounds technical, and it will be, but it's also really important.
Ultimately, this is going to be a once-in-a-lifetime lifting of the curtain to look at how giant multinational companies test, certify, market and sell their products. At Grenfell we're primarily talking about two companies: Arconic (cladding) and Celotex (insulation).
Well, well, well. This - from Paul Hyett's report - is a pretty devastating conclusion for government.
By way of explanation - the government has argued since the fire that its guidance was not to blame for Grenfell and the wider cladding crisis because it did not permit Class 0 cladding. Many in the industry have vociferously argued the opposite.
Hyett (the inquiry's architectural expert) has concluded firmly that Approved Document B did in fact permit Class 0. If he's correct, it would mean the govt has been misleading everyone about its own culpability since Grenfell. (Other experts have taken different positions)
- Claire Williams reduced to tears as she is shown email from morning of the fire
- Stopped public meetings because of resident complaints in Dec 2013
- Admits 'cursory' review of fire strategy document
On the first point, Ms Williams has been pressed repeatedly over a claim that Rydon provided an assurance that the cladding wouldn't burn. Rydon firmly deny this and there is no documentation of it, despite her claim that it was minuted.
Today, she was shown an email from the morning of the fire where she was asked to provide all the relevant documents for the refurbishment and made no reference at all to this assurance. But as questioning began, she was overcome by tears, necessitating a 30 minute break.
Grenfell Inquiry currently on hold because Claire Williams broke down in tears when shown an email she sent to TMO colleagues on the morning of the fire summarising some key documents relating to the refurbishment
Pertinence is that she is being pressed very hard over a claim that Rydon gave her assurances that the cladding they were installing was 'inert' and would not burn. She (along with one other TMO witness) say this was said at a meeting and minuted.
But her first witness statement didn't mention it at all and neither, we have just learned, did this email on the morning of the fire. Yesterday, inquiry counsel asked her if the reason was because it was "an attempt to reconstruct a conversation which did not happen".
Worth taking a moment to reflect that "it's the law" isn't a very good excuse for a minister in a party with an 80 seat majority, who was in fact being asked about plans for new legislation.
It's you guys that make the law, Stephen.
Also, judging by my Twitter and Whatsapp over the last 12 hours, this statement has marked a turning point in the way affected leaseholders view government.
The small remaining 'if only we can get them to listen' optimism has been replaced fairly unmitigated anger.
- TMO project manager destroyed notes and diaries about project a year after fire
- Unable to explain why she didn't query incomplete fire strategy in 2016
- Grilled about risk assessment raising concerns about cladding in Nov 14
The bombshell news from this morning at the inquiry was that Claire Williams "binned" her notes and records when she left the TMO in 2018, despite knowing the public inquiry was underway. We've covered in a story here: insidehousing.co.uk/news/kctmo-pro…
This revelation came from the further news that her colleague, Peter Maddison, had been keeping his diaries and record books at his home and only disclosed them to the inquiry on Friday night. There will be a delay this week so they can be read by all parties.
